FD Calculator – Fixed Deposit Interest & Returns

Introduction

Fixed deposits are one of the safest ways to grow savings—but the final payout depends on the interest rate, the tenure, and how often interest compounds. Trencada's FD Calculator does the math for you: enter the principal, rate, tenure, and compounding frequency, and instantly see the maturity amount, interest earned, and effective annual yield. Every calculation runs locally in your browser—your figures are never uploaded or stored.

How to Use the FD Calculator

Step 1: Choose Your Currency

Pick INR (₹), USD ($), EUR (€), or GBP (£) from the currency selector. Switching currency resets the principal to a sensible default for that currency.

Step 2: Enter the Principal Amount

Set your deposit with the slider or type it directly (default ₹1,00,000, from 1,000 up to 1,00,00,000). This is the amount you invest on day one.

Step 3: Enter the Annual Interest Rate

Set the rate your bank offers with the slider or input (default 7.5%, from 1% to 15%).

Step 4: Set the Tenure

Enter the duration and choose Years, Months, or Days (default 5 Years; from 0.5 up to 30 years).

Step 5: Choose the Compounding Frequency

Select Annually, Semi-annually, Quarterly (the default, and the most common for FDs), Monthly, or Daily.

Step 6: Click "Calculate Returns"

Press Calculate Returns to see your projection. Results also update live as you change any input.

Step 7: Review, Copy, or Reset

See the maturity amount, invested amount, interest earned, effective annual yield, tenure, and compounding frequency. Use Copy Summary to copy the full breakdown to your clipboard, or Reset to restore the defaults and start over.
