About this tool
Find how much a deposit grows with simple or compound interest.
Simple interest adds P × r × t. Compound interest reinvests interest n times a year: A = P(1 + r/n)^(n·t).
Formula: A = P(1 + r·t) · A = P(1 + r/n)^(n·t)
Example: Principal amount = 1,000, Annual interest rate = 5, Years = 10, Interest type = Compound interest, Compounding frequency = Yearly → Final amount = 1,628.89, Interest earned = 628.89.
The rate stays fixed for the whole period and no deposits or withdrawals are made in between. Taxes and fees are not included.
