Compound Interest Table India

How to Read the Compound Interest Table

This pre-computed compound interest table is designed for instant reference without entering any details. The first column shows the principal amount, and subsequent columns display the total amount (principal + interest), total compound interest earned, and the difference between CI and SI for the selected rate, tenure, and compounding frequency.

To find your compound interest: (1) Select the interest rate from the dropdown that matches your investment — 7-7.5% for bank FDs, 7.1% for PPF, 8-12% for mutual funds. (2) Choose the compounding frequency — quarterly for most FDs, annually for PPF, monthly for savings accounts. (3) Find your principal in the first column and read across for the maturity amount and interest earned. The CI vs SI difference column shows exactly how much extra you earn through compounding.

Why Use a Pre-computed CI Table?

A pre-computed table lets you compare multiple investment scenarios instantly without using a calculator. When evaluating fixed deposits from different banks with varying rates, or comparing FD returns with PPF or debt mutual funds, a reference table saves time and reduces errors. Financial advisors frequently use CI tables when explaining the power of compounding to clients.

The table also reveals important patterns. For instance, the difference between CI and SI is negligible for 1-year investments but becomes substantial for 5-10 year periods. At 8% interest, a Rs 10 lakh investment earns Rs 4.69 lakh CI over 5 years versus Rs 4.00 lakh SI — a Rs 69,000 difference. Over 10 years, the CI is Rs 11.59 lakh versus Rs 8.00 lakh SI — a Rs 3.59 lakh difference. This visual insight reinforces the importance of long-term investing.

You can export the entire table as a CSV file for offline use, financial planning spreadsheets, or to share with your investment advisor for portfolio reviews.
