Frequently Asked Questions

I just want a quick answer. Where do I start?

Start with the planner: six questions, then your plan read back in plain English. That is all most people need. The calculator has every input on one screen when you want to go deeper, and your numbers carry over between the two. Everything here is a projection for planning, not financial advice.

The planner or the calculator?

The planner asks six questions, offers optional extras for the things you are worried about, and shows every assumption it makes. The calculator exposes every lever across the About you, Your pots, Markets & inflation, Tax, State Pension and Fine-tuning tabs, including ISAs, gilt ladders, SIPP to ISA migration and the reserve floor. Both build the same plan: start in either and switch any time, and your figures carry over. The planner leaves the fine-tuning options at their defaults, so it is deliberately a little more cautious than a fully detailed plan.

What do I actually need to enter to get a useful answer?

A pot value, the age you want to retire, the age to plan to, and a rough annual income target. Everything else has sensible UK 2026/27 defaults you can refine later.

What do I get back?

Your plan as a story: short chapters in plain English on whether the money lasts, when the State Pension lands, and what the tax looks like. Behind it sits the year-by-year detail, every figure for every year, which you can open from the story or the Year-by-year tab. You can move between the two whenever you like.

What is Goal Seek?

Rather than guessing inputs, Goal Seek works backwards from a question such as "When can I retire?", "How much can I safely spend each year?", or "What pot do I need?", and searches for the answer that reaches the chance of success you're aiming for. Use the Goal Seek button at the top of the calculator. The result is a projection to explore, not financial advice.

Can I save or share my scenario?

Yes. Copy share link generates a link that encodes all your inputs. Anyone who opens it sees the exact same scenario, so you can bookmark it or send it to a partner or adviser. Nothing is stored on a server; the figures travel inside the link itself. When someone opens your link, the plan is shown but not saved on their device unless they choose to keep it, so your numbers do not quietly become their plan.

How are annual withdrawals and investment growth calculated?

Calculation Order

  1. Annual withdrawals are taken first at the beginning of each year
  2. Investment growth is then applied to the remaining pot balance

Example Calculation:

Starting pot: £600,000

Annual withdrawal: £84,000

Investment return: 23.78%


Step 1: £600,000 - £84,000 = £516,000

Step 2: £516,000 × 1.2378 = £638,701

End of year pot: £638,701

Important Note

This methodology assumes withdrawals are taken at the start of each year, reflecting typical pension drawdown practices where income is needed throughout the year for living expenses.

How does pension tax-free cash (25%) work, and why does this calculator use UFPLS?

This calculator uses UFPLS, and that matters

There are two ways to access the tax-free portion of your pension. This calculator models Uncrystallised Funds Pension Lump Sums (UFPLS): the more flexible and often more tax-efficient approach.

UFPLS (this calculator) ✓

Every withdrawal you make is automatically 25% tax-free and 75% taxable. The tax-free benefit is spread across your entire retirement, year by year.

PCLS (traditional approach)

You take the full tax-free lump sum (up to £268,275) in one go at retirement, then all future income from that pot is 100% taxable.

Why UFPLS is often more tax-efficient

  • Spreads the tax-free benefit across retirement: reducing your taxable income every single year rather than just at the start
  • Keeps more income under the higher rate threshold: the 25% tax-free element reduces the taxable amount each year, potentially keeping you in the basic rate band
  • No big upfront decision: you don't need to commit to a large lump sum on day one of retirement
  • Scales with your spending: in years when you withdraw less, you use less LSA; you're not forced to crystallise funds you don't need yet

Worked example: UFPLS vs PCLS on £40,000/year

Scenario: £500,000 pot, £40,000/year needed, basic rate taxpayer, no state pension yet

UFPLS (this calculator):

Withdrawal: £40,000 → £10,000 tax-free + £30,000 taxable

Taxable after personal allowance: £30,000 − £12,570 = £17,430

Tax: £17,430 × 20% = £3,486

PCLS (lump sum taken upfront):

Withdrawal: £40,000 → £40,000 fully taxable

Taxable after personal allowance: £40,000 − £12,570 = £27,430

Tax: £27,430 × 20% = £5,486

Annual saving with UFPLS: £2,000

How the LSA limit applies

  • The total tax-free cash you can take across your lifetime is capped at £268,275 per person
  • Any lump sum taken at retirement counts toward this limit and reduces future UFPLS tax-free entitlement
  • Once your LSA is exhausted, all future withdrawals are fully taxable
  • Each person in a couple has their own separate £268,275 LSA
  • State Pension is always fully taxable; no tax-free portion applies

What's the difference between Drawdown, Annuity, and Hybrid?

The Retirement Strategy setting changes how your pension pot is used. Each trades off flexibility against income certainty.

Drawdown

Keep the pot invested and withdraw flexibly year-by-year. Maximum flexibility and growth potential, but you carry all the market and longevity risk.

Annuity

Exchange all (or part) of the pot for a guaranteed income for life. No market risk, income never runs out, but no upside if markets outperform, and less flexibility.

Hybrid

Annuitise a percentage of the pot to buy a baseline "floor" income, then draw flexibly from the remainder. A pragmatic middle ground used by many retirees.

Annuity quotes are generated from current market rates and are sensitive to age, joint-life, escalation (level / fixed / RPI) and term. See the Annuity Cost tab to explore quotes standalone.

What does "Freeze Growth & Inflation Rates" do?

This feature allows you to maintain consistent economic conditions across multiple calculations:

When Enabled (Frozen)

  • • Uses the same growth and inflation rates
  • • Maintains scenario consistency
  • • Ideal for testing parameter changes
  • • Shows "Frozen Conditions" badge

When Disabled

  • • Generates new random scenarios
  • • More realistic volatility modeling
  • • Different results each calculation
  • • Better for stress testing

How do Monte Carlo simulations work?

Instead of running one projection with a fixed return and inflation rate, the calculator runs thousands of projections where each year's return and inflation are drawn at random from a normal distribution around the mean you set. This reveals the full range of outcomes, not just the average.

What you see in the results

  • Probability of success: the share of simulated futures where your pot lasted to your target age.
  • Range of outcomes: best-case, median, and worst-case scenarios.
  • Economic factors panel: the distribution of returns and inflation used.

The default is 1,000 simulations, which balances statistical reliability with run time. You can adjust this on the Fine-tuning tab; higher counts tighten the probability estimate but take longer to compute in the browser.

What is the "income from dividends" option?

It models holding part (or all) of your pot in income-paying investment trusts and living off the dividends they pay, rather than selling units to fund spending. Set the slice to, say, 20-40% to combine it with normal drawdown, or to 100% to fund the whole plan from dividends. The capital is never sold to pay you; only the dividends are spent. You can add it on the planner ("Want part of your income to come from dividends?") or in the calculator's Fine-tuning tab.

Why do these trusts seem to yield 8%+ over time? Can I get that?

No, not as a new buyer. A figure like 8% is usually "yield on cost": this year's dividend measured against what someone paid years ago. A new buyer today gets the current yield, which for a diversified basket of UK income trusts is roughly 3.5 to 4.5%. The high yield-on-cost figure really just shows that the dividend has grown over the years, which is the genuine appeal, but it is not a return you can go and buy. The model uses a starting yield you set (default 4%, after charges), not a flattering yield-on-cost number.

What happens in a market crash?

The share price falls, but a dividend is paid out of company profits, not the share price, so the income usually keeps arriving. That is the whole point: because you are not forced to sell anything at a low point, a crash hurts far less than it does in normal drawdown. The risk you take on instead is a dividend cut. In a deep, broad downturn even steady trusts can trim their payout, so the model builds in a crash-year cut (correlated with the bad market year) and a small reserve to cushion it.

So what is the real risk?

Three things, none of which a rosy headline yield mentions. A dividend cut in a severe downturn. Concentration, if you lean on a handful of trusts or one part of the market, a problem there hits your income directly, so a spread across sectors and regions matters. And inflation outrunning the dividend, your income needs to keep growing in real terms, or its buying power slips even while the cash figure holds. The plan shows you an honest "if dividends fell 20%" line so you can sense-check it against your essential spending.

How are the dividends taxed?

It depends where the trusts are held. Inside a pension (the default), the dividends are taxed as income when you draw them: 25% tax-free up to your lump-sum allowance, the rest at your normal rate, split across both partners' allowances for a couple. Inside an ISA they are completely tax-free. The model never charges dividend tax inside the wrapper, only the income tax on drawing from a pension, which is exactly how it works in real life.

What is the gilt ladder option?

It carves out part of your pot into a low-variance, fixed-yield bucket (around 4–5% at current gilt yields) that funds your first few years, so a market crash early in retirement doesn't force you to sell investments cheap. Each year a rung matures and pays out in full; any surplus over what you spend is swept into your reserve. Modelled inside your SIPP by default, or outside it if you tick that box. This is a modelling tool, not financial advice.

What does "Fill basic-rate band first" do?

Instead of spending your ISA and savings before your pension, it draws taxable pension up to the top of the basic-rate band each year (using both partners' allowances) and only then tops up from the tax-free reserve. This often avoids the higher-rate tax in later years that spending the ISA first can cause. It changes the order money is drawn, not how much you spend.

What does SIPP → ISA migration do?

Each year it draws your SIPP up to the top of the basic-rate band, beyond what you need to spend, and sweeps the net proceeds into your ISA, up to £20,000 per person. It moves money from a wrapper where withdrawals are taxed into one where future growth and withdrawals are tax-free, using tax bands in low-income years that would otherwise go to waste. You pay a little tax now, so it pays off if your rate later is the same or higher. It is not an inheritance-tax play: ISAs sit in your estate too, and pensions are actually outside it until the April 2027 change. Large deliberate recycling breaches HMRC rules; this is a projection, not advice.

What is the reserve floor ("Never spend the reserve below")?

It ring-fences a fixed amount of your combined ISA, savings and cash as an untouchable buffer, in today's money. Once your reserve hits that floor, further income comes from the pension instead, even if that pushes you into higher-rate tax. Leave it at £0 for no floor (the reserve can be fully spent).

What is the lifetime lump sum allowance and how does it work?

The UK lifetime lump sum allowance is a total limit of £268,275 on the amount you can take tax-free from your pension over your lifetime. This replaced the previous lifetime allowance rules in April 2024.

How it works:

  • You can normally take 25% of each pension withdrawal tax-free
  • But the total tax-free amount across ALL your pensions cannot exceed £268,275
  • Once you've used up this allowance, all future pension income is taxable
  • This applies whether you take a lump sum at retirement or spread withdrawals over time

Detailed Example - £1.5m pension pot withdrawing £90k annually:

YearWithdrawalTax-freeTaxable
1-2£90,000£22,500£67,500
3-5£90,000£22,500£67,500
6-8£90,000£22,500£67,500
9-11£90,000£22,500£67,500
Year 12£90,000£25 remaining£89,975
Year 13+£90,000£0£90,000

Total tax-free used: £268,275 (limit reached in year 12)

Why this matters for large pensions:

  • A £1m+ pension pot would normally allow £250k+ tax-free (25%)
  • But the £268,275 lifetime limit caps this significantly
  • Your effective tax-free rate drops from 25% to much lower over time
  • Planning withdrawals becomes crucial to maximize the allowance

Our calculator shows you:

  • Exactly when your Lifetime Lump Sum Allowance will be exhausted
  • Year-by-year breakdown of tax-free vs taxable amounts
  • Orange "⚠️ Tax-free ends" alert when the limit is reached
  • How to optimize withdrawal timing to maximize benefits

Important: This limit applies across all your pension schemes combined. For the most current information, see the official government guidance.

How are UK income tax calculations performed?

Tax calculations follow current UK income tax rules with separate calculations for each person:

Default Tax Rates (2026/27)

• Personal Allowance: £12,570

• Basic Rate: 20% (£12,571 - £50,270)

• Higher Rate: 40% (£50,271 - £125,140)

• Additional Rate: 45% (£125,140+)

These thresholds are frozen by HM Treasury through April 2028.

Tax Calculation Notes

  • • Each person's income is calculated separately
  • • Includes pension withdrawals, state pension, and additional income
  • • Tax rates can be customised in the calculator's Tax tab
  • • Does not include National Insurance contributions

How does the Marriage Allowance work?

If you're married or in a civil partnership and one of you earns under the personal allowance (£12,570) while the other is a basic-rate taxpayer, the lower earner can transfer £1,260 of their unused allowance to the higher earner, saving the couple £252/year in tax.

How the calculator applies it

  • Turn on Enable Marriage Allowance in the Tax tab.
  • Each year, the calculator checks whether the conditions are met and, if so, transfers £1,260 of allowance to the basic-rate partner.
  • The Personal Allowance Usage panel on the Year-by-Year page reflects the effective allowance (e.g. £13,830 for the recipient, £11,310 for the transferor) so the figures reconcile with the tax paid.

Marriage Allowance is only useful when the lower earner has unused personal allowance. If both partners have income above £12,570, the toggle has no effect.

How is the state pension inflated each year?

Under the UK triple lock, the state pension rises each April by the highest of: CPI inflation, average earnings growth, or 2.5%. This happens regardless of whether anyone has started claiming it yet; the rate set by government applies uniformly to everyone with full entitlement.

Calculator behaviour

  • No inflation applied: state pension stays at today's £ value forever (useful for real-terms projections).
  • Inflate state pension rate every year (default): the rate compounds from today, so your and your partner's pension both reflect the same current rate in any given year.
  • Triple Lock toggle: when on, annual growth is max(inflation, earnings growth, 2.5%) rather than inflation alone.

Does "Annual Income Required" include the state pension?

The State Pension counts toward Annual Income Required toggle (Tax tab) controls which interpretation you're using. Both are valid; pick the one that matches how you think about your target.

ON (default)

Your target is total income. Once the state pension starts, your pension pot only funds the gap between state pension and target, so withdrawals fall.

OFF

Your target is what you want from the pot. State pension arrives as bonus income on top, so your total spend exceeds the target once it starts.

How accurate are the projections?

These projections are estimates based on the assumptions and parameters you provide. Actual investment returns, inflation rates, and tax rules may differ significantly from projections. The calculator is designed for planning purposes and should not be considered as financial advice.

Factors That May Affect Accuracy

  • • Market volatility and economic cycles
  • • Changes in tax legislation
  • • Inflation variations
  • • Personal circumstances changes
  • • Pension rule modifications

Are tax rates and pension rules kept up to date?

The calculator uses current UK tax rates and pension rules as defaults, but you can change these in the calculator.

Important

Always verify current tax rates and pension rules with HMRC or consult a qualified financial advisor for the most up-to-date information.

Can non-UK residents use this calculator?

Yes! The calculator can be adapted for non-UK residents by adjusting the tax settings and disabling UK-specific pension benefits.

Key Steps for Non-UK Residents:

  1. Enable "Disable 25% Pension Tax-Free Cash" switch on the Your pots tab
  2. Adjust tax rates on the Tax tab to match your country's rates
  3. Set state pension amounts to zero or your country's equivalent
  4. Modify personal allowance to match your tax-free threshold

How do I disable the 25% pension tax-free cash?

On the Your pots tab, you'll find a switch labeled "Disable 25% Pension Tax-Free Cash".

When to Enable This Switch:

  • You are not a UK tax resident
  • Your country doesn't offer tax-free pension withdrawals
  • You want to model pension taxation without UK benefits

When enabled, all pension withdrawals will be subject to full taxation according to your configured tax rates.

How do I adjust tax rates for my country?

Use the Tax tab to configure your country's income tax system:

Tax Configuration Examples:

Flat Tax System (e.g., some Eastern European countries):
  • Personal Allowance: Set to your tax-free threshold
  • Basic Rate: Set to your flat tax rate (e.g., 10%)
  • Higher Rate: Same as basic rate
  • Additional Rate: Same as basic rate
Progressive Tax System (e.g., USA, Canada, Australia):
  • Personal Allowance: Standard deduction or tax-free threshold
  • Basic Rate Threshold: First tax bracket limit
  • Higher Rate Threshold: Second tax bracket limit
  • Rates: Match your marginal tax rates

Important Note

Consider federal, state/provincial, and local taxes. You may need to combine rates or run separate calculations for different tax jurisdictions.

How do I handle my country's state pension equivalent?

Use the State Pension tab to configure your country's public pension system:

Configuration Options:

  • No State Pension: Set amounts to £0 if your country doesn't have a public pension system
  • Social Security (USA): Enter your estimated annual Social Security benefit
  • CPP/OAS (Canada): Enter combined Canada Pension Plan and Old Age Security amounts
  • Age Pension (Australia): Enter your estimated Age Pension amount
  • State Pension (Other): Enter your country's equivalent annual amount

Convert amounts to GBP using current exchange rates, or work in your local currency and convert final results.

How do I handle different currencies?

The calculator works in GBP, but you can adapt it for other currencies:

Currency Options:

  • Method 1: Convert all inputs to GBP, then convert results back
  • Method 2: Use your local currency amounts directly (ignore £ symbols)
  • Method 3: Scale inputs proportionally (e.g., $100k pension = £100k input)

Example for USD:

If you have a $500,000 401k and want $40,000 annual income, you can either:
• Convert to GBP: £400k pot, £32k income (at 1.25 exchange rate)
• Use direct amounts: Enter 500000 for pot, 40000 for income, treat results as USD
