FD Calculator - Fixed Deposit Maturity Calculator

What is a Fixed Deposit?

A Fixed Deposit (FD) is one of the safest and most popular savings instruments in India. You invest a lump sum for a fixed tenure at a predetermined interest rate, and your money grows steadily until maturity. Unlike market-linked investments, an FD offers guaranteed, predictable returns - making it ideal for conservative savers, retirees and anyone building an emergency fund in Salem and across Tamil Nadu.

With YoursPay, opening a fixed deposit is simple and transparent. Use the FD calculator above to see exactly how much your deposit will grow before you invest.

Benefits of a Fixed Deposit

• Guaranteed returns - your interest rate is locked in for the full tenure, regardless of market movements.
• Capital safety - your principal is secure, making FDs one of the lowest-risk options.
• Flexible tenures - choose terms from a few months to several years to match your goals.
• Higher rates for seniors - senior citizens typically earn additional interest.
• Loan against FD - borrow against your deposit without breaking it in an emergency.

How FD Interest is Calculated

Fixed deposit interest is usually calculated using compound interest, most commonly compounded quarterly. The maturity amount is given by the formula:

A = P × (1 + r/n)^{n × t}

Where A is the maturity amount, P is the principal (deposit amount), r is the annual interest rate (as a decimal), n is the number of times interest is compounded per year (4 for quarterly), and t is the tenure in years. The calculator above uses quarterly compounding to estimate your returns.
