UK Pension Drawdown Calculator
Model flexi-access drawdown: how long does your pot last at your chosen income?
Inputs
Money Purchase Annual Allowance drops future contributions to £10,000/yr once flexi-access drawdown starts.
How it works
Each year: balance = balance × (1 + return) − withdrawal. Stops when balance ≤ 0 or 60 years reached. Beyond 25% tax-free portion, drawdowns are taxed as income.
Frequently asked questions
Is this guaranteed?
No — these are projections that assume your inputs hold. Real markets and life are variable.
What's the 4% safe-withdrawal rule?
The Trinity Study suggests withdrawing 4% of a balanced portfolio in year one and adjusting for inflation typically lasts 30+ years.
Should I max out my 401(k)?
At minimum, capture the full employer match — that's free money. Beyond that, balance against debt payoff and emergency reserves.
Roth vs. Traditional?
Roth wins if you'll be in a higher tax bracket in retirement; Traditional wins if you'll be in a lower bracket.
When should I start saving?
Immediately. The single biggest variable in retirement success is years of compounding.
