Fixed Deposit Calculator

Formula and methodology

Savings products usually use simple interest, compound interest, or scheme-specific rules. The calculator applies the relevant formula based on the selected tool and input frequency.

WealthWiseGrow keeps calculator inputs private in your browser wherever possible. The result should be treated as an educational estimate and reviewed against the official product terms, bank quote, fund document, tax rule, or salary structure that applies to your situation.

Example interpretation

For example, two deposits with the same annual rate can produce different maturity amounts if one compounds quarterly and the other annually. Use the calculator to compare real maturity value, not only the headline rate.

After calculating, compare at least two scenarios: a conservative case and an optimistic case. This helps you avoid planning around a single number that may not survive changes in income, interest rates, inflation, tax rules, or market returns.

Key assumptions

• - Interest rates may change for new deposits or future contributions.
• - Tax treatment can vary based on income slab, product type, and holding period.
• - Premature withdrawal rules may reduce the final value.

Common mistakes

• - Comparing only the advertised interest rate.
• - Forgetting tax on interest income.
• - Using long lock-in products for short-term emergency money.
