How this calculator works
A = P × (1 + r / n)nt
P is principal, r is annual rate in decimal, n is compounding periods per year and t is time in years.
Example

Frequently asked questions
What is compound interest?
Compound interest is interest earned on the principal plus accumulated interest.
Does more frequent compounding increase the result?
For the same nominal annual rate, more frequent compounding usually produces a slightly higher future value.
Does this include regular contributions?
No. Use SIP or RD calculators for recurring contributions.
