- What is the compound interest formula?
- A = P × (1 + r ÷ n)^(n × t), where P is the principal, r is the annual rate as a decimal, n is the number of compounding periods per year, and t is the time in years. Interest earned is A − P.
- Which compounding frequencies are supported?
- Yearly (n = 1), half-yearly (2), quarterly (4), monthly (12), and daily (365). Results are estimates — banks may use different day-count or rounding rules.
- Does compounding more often really matter?
- Yes, but less than people expect at ordinary rates. 10,000 at 10% for 10 years grows to about 25,937 yearly and about 27,070 monthly — the frequency helps, while the rate and the time do most of the work.
- Does this include regular deposits?
- No. This version compounds a single principal over time. It does not model SIPs, recurring contributions, or withdrawals.
- Simple vs compound interest?
- Simple interest is charged only on the original principal. Compound interest adds each period’s interest to the balance, so later periods earn interest on interest. Pick the calculator that matches the rule you are checking.
