Crypto Compound Interest Calculator
Project portfolio growth using compound interest. Enter initial investment, monthly contribution, APY, and time horizon.
How This Tool Works
Compound interest is the process of earning returns on both your initial investment and accumulated gains over time.
A = P × (1 + r/n)^(n×t) + PMT × [((1 + r/n)^(n×t) − 1) / (r/n)]
Where: P = Principal, r = Annual rate, n = Compounding frequency, t = Years, PMT = Monthly contribution.
Even modest monthly contributions dramatically accelerate portfolio growth over multi-year horizons — the earlier you start, the more powerful the effect.
