Interest Calculator
Savings growth with simple or compound interest.
Simple: A = P(1 + rt) · Compound: A = P(1 + r/n)^(nt), where n is the compounding frequency per year.
- Simple vs compound interest — what is the difference?
- Simple interest pays on the original principal only. Compound interest pays on principal plus previously earned interest, so the balance grows faster.
- Does compounding frequency matter?
- Yes — daily beats monthly, and monthly beats annually, all else equal. The difference grows with the rate and term.
- Is this after tax?
- No, this is a pre-tax projection. Interest taxation varies by jurisdiction and tax bracket.
