Compound Interest Calculator
The magic of compound interest lies in its ability to generate exponential growth by reinvesting the interest earned on your principal amount. This concept fuels everything from personal savings to large-scale business investments.
Unlike simple interest, compound interest accelerates wealth accumulation over time. Using an accurate compound interest calculator is key to optimising your investments and ensuring your ROI meets expectations. Learn about Share.Market’s compound interest calculator below:

Compound Interest Calculator Formula
Share.Market follows an internationally recognised method for calculating the total compound interest accrued. The formula is:
A = P(1 + r/n)^(nt)
Where:
- A: Amount after time t
- P: Principal amount (initial investment)
- r: Annual interest rate (as a decimal)
- n: Number of times interest is compounded per year
- t: Time in years
Consider this as an example: You invest ₹10,000 in a fixed deposit for 5 years at an annual interest rate of 8%, compounded quarterly.
| Year | Principal at Beginning of Year (₹) | Interest Earned (₹) | Principal at End of Year (₹) |
| 1 | 10,000 | 200 | 10,200 |
| 2 | 10,200 | 204 | 10,404 |
| 3 | 10,404 | 208.1 | 10,612.10 |
| 4 | 10,612.10 | 212.2 | 10,824.30 |
| 5 | 10,824.30 | 216.5 | 14,859.47 |
Let’s use the above formula and cross-verify the table given above:
- Principal (P) = ₹10,000
- Annual Interest Rate (r) = 8% = 0.08
- Number of Times Compounded per Year (n) = 4 (quarterly)
- Time (t) = 5 years
Calculation:
A = 10000*(1 + 0.08/4)^(4*5)
Calculating this, we get:
A ≈ ₹14,859.47
The final amount you will get after 5 years is approximately ₹14,859.47.
Simple Interest vs Compound Interest
Here’s a look at Simple Interest vs. Compound Interest, lessons you learned in middle school math that continue to shape your financial decisions:
| Aspect | Simple Interest (SI) | Compound Interest (CI) |
| Formula | SI = P × R × T / 100 | CI = P × (1 + R/n)^(nt) – P |
| Interest Calculation | Interest is calculated only on the principal amount | Interest is calculated on both the principal and accumulated interest |
| Time Period | Linear growth of interest over time | Interest grows exponentially over time |
| Frequency of Interest | Interest is calculated annually | Interest can be compounded annually, quarterly, monthly, or daily |
| Growth of Amount | Amount grows at a constant rate | Amount grows at an accelerating rate due to compounding |
| Final Amount Formula | A = P + SI | A = P × (1 + R/n)^(nt) |
| Ease of Calculation | Easier to calculate with fewer variables | Slightly more complex due to multiple factors |
| Interest Impact | Lower interest impact over time | Higher interest impact over time due to compounding |
