The power of compounding
Compound interest earns returns on both your principal and the interest already accrued, which is why balances accelerate over time. This calculator uses the standard formula A = P(1 + r/n)nt for the principal, plus the future-value-of-an-annuity formula for recurring contributions. More frequent compounding and regular contributions both increase the final total. Figures are estimates for planning, computed locally in your browser.
