How this calculator works
This calculator uses compound interest with monthly compounding to project your pension pot value at your target retirement age. It adds your personal contributions and any employer match each month, then applies the selected annual growth rate.
The estimated annual income uses a 4% sustainable withdrawal rate — a common rule of thumb for how much you could draw down each year without running out of money over a 30-year retirement.
This is an illustrative projection, not a guarantee. Actual returns depend on market conditions, fund selection, fees, and tax treatment. For a more realistic picture that accounts for market uncertainty, try Slate's full Monte Carlo simulation engine — which runs 1,000 scenarios per portfolio.
