Compound Interest Calculator
Project the maturity value of a lumpsum and (optionally) regular contributions under compound interest. Choose any compounding frequency, optionally add an inflation rate for the real value of the corpus, and view the year-wise growth schedule along with a comparison against simple interest.
Principal and Rate
Tenure
Regular Contributions (Optional)
SIPs are typically end-of-period.
Inflation Adjustment (Optional)
If entered, the calculator also shows the real (today’s-value) maturity and real return.
Corpus Composition
Composition of the final maturity value: principal contributed (lumpsum + recurring) versus the interest component earned through compounding.
Year-wise Growth Schedule
Schedule simulated monthly with interest applied at the chosen compounding frequency. Contributions added at the chosen timing (beginning / end of period).
Compound vs Simple Interest (Lumpsum portion)
Comparison shown on the lumpsum principal only (excluding recurring contributions). Simple Interest = P x R x T; Compound Interest reflects the chosen compounding frequency.
