Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Financial
Investment Return Calculator
Calculate the annualized rate of return on an investment given its initial cost, additional contributions, final value, dividends received, and holding period. Use it to compare investments of different durations on a common, apples-to-apples basis.
Economics
Compound Interest Calculator
Project the future value of a lump-sum investment when interest is reinvested each year using A = P · (1 + r)ᵗ. The simplest compounding model — assumes annual compounding, a constant rate, and no additional contributions or withdrawals.
