Future Value of Growing Annuity Calculator: Plan Your Financial Growth

The tool converts a stream of rising payments into a single future value using the growing-annuity formula. Enter the first payment, interest rate, payment-growth rate and number of periods; the calculator then applies $$FV = P times rac{(1+r)^n-(1+g)^n}{r-g}$$. Example: $750 growing 1.5 % with 3.8 % interest for 12 years becomes ≈ $12,016.28. Long-term U.S. stocks returned ~10 % annually 1926-2022, a common benchmark for r (S&P Dow Jones Indices, 2023).
