How it works
State pensions across Europe are under pressure from ageing populations, which makes private saving increasingly important. The good news: thanks to compound growth, modest monthly contributions started early routinely outgrow much larger contributions started late.
Enter your age, planned retirement age, monthly contribution and an expected annual return to project your pension pot. The calculator also estimates the monthly income that pot could sustainably provide using the widely-cited 4% withdrawal rule.
Future value with monthly compounding
FV = P₀ × (1 + r)ⁿ + C × ((1 + r)ⁿ − 1) ÷ r
MonthlyIncome ≈ FV × 4% ÷ 12P₀ = current savings, C = monthly contribution, r = annual return ÷ 12, n = months until retirement. The 4% rule is a rule of thumb, not a guarantee.
