Pension Drawdown Calculator — Plan Your Retirement Income — UK 2026
Calculate sustainable income from pension drawdown in the UK. Find out how long your pension pot will last at different withdrawal rates and compare with.
Since pension freedoms were introduced in 2015 most UK retirees now choose flexible drawdown over buying an annuity. Drawdown lets you keep your pension invested while withdrawing income as needed. The challenge is balancing withdrawing enough to enjoy retirement while not running out of money. Withdrawing too much too early especially during market downturns can deplete your pot decades before you expected. Our calculator models different withdrawal rates and investment returns to show how long your pension will last.
How much can I safely withdraw from my pension?
The widely cited 4% rule suggests withdrawing 4% of your pension pot in year one then adjusting for inflation each year. On a £200000 pot that means £8000 in the first year or £667 per month. Research suggests this has a high probability of lasting 30 years. However in the UK with lower expected returns many advisors recommend 3.5% as a safer withdrawal rate especially if retiring before 60.

Understanding Your Investment Returns
This calculator projects your returns using compound interest, where your earnings generate their own earnings over time. The power of compounding means that even small regular investments can grow into substantial wealth over long periods. For example, investing just Rs 5,000 per month at 12% expected returns for 25 years can grow to over Rs 1 crore — of which only Rs 15 lakh is your own money and Rs 85 lakh is compounding returns. The key factors that determine your final corpus are: the amount invested, the rate of return, the duration of investment, and the frequency of compounding.
Important Considerations
Past returns do not guarantee future performance, especially for market-linked instruments like mutual funds and equities. The returns shown are estimates based on the rate you enter. Equity investments carry market risk but have historically delivered 12-15% CAGR over 15+ year periods in India. Fixed income options like PPF (7.1%) and FD (6-7.5%) offer lower but more predictable returns. Diversifying across asset classes — equity, debt, gold, and real estate — reduces overall portfolio risk while optimizing returns for your risk tolerance.

How much can I safely withdraw from my pension?
The widely cited 4% rule suggests withdrawing 4% of your pension pot in year one then adjusting for inflation each year. On a £200000 pot that means £8000 in the first year or £667 per month. Research suggests this has a high probability of lasting 30 years. However in the UK with lower expected returns many advisors recommend 3.5% as a safer withdrawal rate especially if retiring before 60.
Should I take the 25% tax-free lump sum?
You can take 25% of your pension tax-free and this is one of the most generous tax breaks available. On a £200000 pot that is £50000 tax-free. However taking the full lump sum at once might not be optimal. Some people phase their tax-free withdrawal over several years by crystallizing portions of their pension each year. Consider your actual cash needs and tax position before deciding.
Is drawdown or annuity better?
Drawdown offers flexibility and potential for higher income if investments perform well but carries the risk of running out of money. Annuities guarantee income for life but are inflexible and current rates mean lower initial income. Many retirees use a combination buying an annuity to cover essential expenses and keeping the rest in drawdown for flexibility. The right mix depends on your health risk tolerance and other income sources.
What is compound interest and why does it matter?
Compound interest means you earn interest on your interest, not just your principal. Over long periods, this creates exponential growth — even small regular investments can grow into substantial wealth over 15-25 years.
Should I invest regularly or as a lump sum?
Regular investing (dollar-cost averaging) smooths out market volatility by buying at various price points. Lump sum investing works better if markets are undervalued. For most people, regular monthly investing is simpler and more disciplined.
How much should I invest monthly to reach my goal?
The amount depends on your target, timeline, and expected returns. Use this calculator to model different scenarios. The key factors are starting early, investing consistently, and reinvesting returns.
Are investment returns taxable?
Tax treatment varies by investment type and country. Capital gains, dividends, and interest income may be taxed differently. Consult a tax professional for advice specific to your situation and jurisdiction.
