How to Use the Retirement Calculator
Enter your current age, planned retirement age, life expectancy, current savings, monthly contributions, and expected investment return. Then set your desired monthly spending in retirement to see if your savings will last and whether you're on track.
The 4% Rule
A widely used guideline is the 4% rule — in retirement, you can withdraw 4% of your savings per year (adjusted for inflation) and your pot should last at least 30 years. To find how much you need to retire, multiply your desired annual spending by 25. For example, £3,000/month = £36,000/year × 25 = £900,000 target.
Pre vs Post-Retirement Returns
During accumulation (working years), you can typically afford more risk — stocks and growth assets — aiming for 6–10% returns. In retirement (drawdown phase), most advisors recommend shifting to more conservative assets (bonds, income funds) targeting 3–5% to reduce volatility and preserve capital.
Why Inflation Matters So Much in Retirement
Inflation compounds against you in retirement. At 3% inflation, your purchasing power halves every 24 years. This calculator adjusts your spending target for inflation so you can see what your monthly spending in retirement will really cost in future money.
// The 4% Rule
Multiply your desired annual spending by 25 to get your retirement target. £2,500/mo = £750,000 needed.
// Start Now
Every decade you delay roughly halves what you'll have. Starting at 25 vs 35 can mean double the final pot.
// State Pension
Don't forget state/social pension income — it reduces how much your private pot needs to cover each month.
// 15% Rule
Many advisors suggest saving 15% of gross income for retirement including any employer match contributions.
