Compound Interest Calculator
Estimate savings growth with recurring contributions and compound interest.
How compound interest works
Compound interest means profit is added to the deposited amount, and the next interest is charged on the increased amount. Monthly contributions accelerate growth.
Each month: Amount = Amount × (1 + Rate ÷ 12) + Contribution
Time is the main factor: the longer compound interest works, the stronger the growth becomes, because interest is charged on interest.
Compound interest FAQ
How is compound interest different from simple interest?
Simple interest is charged only on the initial amount. Compound interest is charged on the initial amount plus all previously accrued interest, so capital grows faster.
Does the calculator include taxes and inflation?
No, the calculator shows the nominal profit at the deposit rate. The real return will be lower due to income tax and inflation.
How to get a bigger result?
The more frequent the contributions and capitalization and the longer the term, the higher the result. Monthly contributions give a noticeably better result than a one-time deposit of the same amount.
