Compound Interest Calculator
Compound interest pays interest on your interest. Choose how often the interest is compounded — yearly, half-yearly, quarterly or monthly — to see how the same rate produces different results.
Compound Interest Calculator
How this calculator works
A = P × (1 + r/n)^(n × t), where n is the number of compounding periods per year.
- More frequent compounding gives a slightly higher maturity value at the same nominal rate.
- Interest earned = maturity amount − principal.
