What is the Pension Drawdown vs Annuity Calculator?
The Pension Drawdown vs Annuity Calculator helps you compare two main retirement income options: buying an annuity (guaranteed income for life) or using pension drawdown (flexible withdrawals from your pot). It shows annual income, cumulative totals, break-even analysis, and year-by-year projections so you can see which option delivers more over your chosen planning period—and highlights a clear “winner” (drawdown, annuity, or equal) with a short explanation.
How the Calculator Works?
Enter your pension pot size, current age and life expectancy. Configure annuity options (rate, type—level or escalating) and drawdown options (withdrawal style, investment return, fees). The calculator projects both options to your life expectancy and shows a winner callout, annual income, cumulative totals, break-even age and a full year-by-year table. Returns are not linear; the model is illustrative.
Step One: Enter Your Profile
Add your pension pot size, current age and expected life expectancy (e.g. 90). The comparison runs from your current age to the end of that period.
Step Two: Configure Annuity Options
Set the annuity rate (UK 2026 level rates often 7–7.5% for 65–67; get a quote) and type: level (fixed) or escalating (increases each year but starts lower). For escalating, set the escalation rate and starting % of level.
Step Three: Configure Drawdown Options and Review Comparison
Choose level income (exhaust fund by life expectancy) for a direct comparison with a level annuity, or a percentage of pot (SWR-style). Set investment return and fees. Review the winner callout, annual income, cumulative totals, break-even age and year-by-year table. Export to CSV if needed.

Annuity rates and investment returns are estimates. Drawdown carries investment and longevity risk. Always consult a qualified financial advisor.

What is the Pension Drawdown vs Annuity Calculator?
A UK-specific tool that compares annuity income (guaranteed for life) with pension drawdown (flexible withdrawals) over your planning period, shows which option delivers more total income, and provides break-even analysis and year-by-year projections.
What is the difference between annuity and drawdown?
An annuity is guaranteed income for life purchased with your pot. Drawdown lets you keep your pot invested and withdraw flexibly, but it can run out if you live too long or withdraw too much.
Which is better: annuity or drawdown?
It depends on your circumstances. Annuities provide security; drawdown offers flexibility and potential for higher returns but carries risk. The calculator helps you compare based on your specific situation.
What is a typical annuity rate?
UK rates vary by age, health and type. In 2026, level rates are often around 7–7.5% for ages 65–67; get a quote as rates vary by provider.
What is a safe withdrawal rate for drawdown?
A common rule of thumb is 3–4% of your pot per year. The calculator also offers a “level income (exhaust fund)” option for a fair comparison with a level annuity.
What is break-even age?
When cumulative drawdown income exceeds cumulative annuity income. If you live beyond this age, drawdown may provide more total income.
Does the calculator account for tax?
It focuses on gross income comparisons. Both options are subject to income tax; the calculator does not include tax.
What about inheritance?
Annuities typically provide no inheritance. Drawdown allows you to pass remaining funds to beneficiaries.
Can I combine annuity and drawdown?
Yes. Many people use a combination. The calculator compares pure options; you can model combinations by adjusting inputs.
Does it account for inflation?
Level annuities are nominal (no increase); escalating annuities start lower and increase each year. An inflation-risk warning appears for level annuities.
What if I live longer than expected?
Annuities protect against longevity risk. Drawdown may run out if you live too long. The calculator projects to your chosen life expectancy to help you assess this.
How do health and postcode affect a real annuity quote?
Providers can price using age, health, lifestyle, postcode and chosen protections. Medical conditions or smoking can sometimes qualify for enhanced income. A calculator rate is only an illustration. Obtain several current quotes using accurate information before comparing a guaranteed offer with drawdown.
Should I buy an annuity all at once?
Not necessarily. Phased annuitisation can secure essential income gradually and leave flexibility, while later age or health changes may produce a different rate. Rates can also fall. Compare staged purchases with a single purchase and include the investment risk carried in the meantime.
What does inflation protection cost?
An escalating annuity normally starts lower than a level annuity because payments are designed to rise. It may take many years for cumulative income to catch up. Compare spending needs, other inflation-linked income and life expectancy rather than choosing the highest starting amount by default.
Can drawdown and an annuity use different parts of the same pension?
Often, yes. Part of a pension can buy guaranteed income while the rest stays in drawdown, subject to the provider’s options. That can cover the basic bills and keep other spending flexible. Check the fees and whether the current provider can handle the split without unnecessary cost.

Behind Retirement Calculators
Built from the questions I was asking myself
I'm Ryan, the person behind Retirement Calculators. I started the site after selling an online business and trying to understand what our pensions, ISAs, investments and property actually meant for the way we wanted to live.
The calculators are built around those real decisions: whether you could work less, retire earlier, spend more now or use your money differently. They will not give you a perfect answer, but they can make the trade-offs much easier to see.
