📈 Compound Interest

How much does money grow over time? Enter the principal, rate and years to see the final amount with a year-by-year growth table. You can include a monthly deposit to model regular savings.

How to use the Compound Interest

  1. Enter the starting amount (principal).
  2. Enter the yearly rate (%) and the number of years; choose how often interest compounds.
  3. Optionally add a monthly deposit, then press Calculate.
Example: Rs 1,00,000 at 10% compound interest per year becomes Rs 1,61,051 in 5 years — Rs 61,051 of it is pure interest.
