How to Calculate Compound Interest?
The compound interest formula used by these calculators and standards are accepted universally. He basic formal for calculating a compound interest is :
A= P(1+r/n)^nt
Where:
“A “ stands for Amount on maturity
“P” is principal amount
“r “ is expected Rate of return
“n” stands for the number of times the interest compounds in a year, for instance if the rate of return is monthly then the value of n will be 2 .
“t” is simply the number of years for which you are investing the amount.
Now let us understand how this formula works. Let us suppose that you are investing 100 rupees with an annual expected rate of return of 10%. The investment is done for 5 years.
| Principal | Rate of return in % | Year | Interest | Amount (Principal + Interest) |
| 100 | 10 | First | 10 | 110 |
| 110 | 10 | Second | 11 | 121 |
| 121 | 10 | Third | 12.1 | 133.1 |
| 133.1 | 10 | Fourth | 13.31 | 146.41 |
| 146.41 | 10 | fifth | 14.641 | 161.051 |
Inserting the same value in the formula
A= 100(1+10)^5
A= 100 (1.10)^5
A= 100 (1.61051)
A= 161.051
So this is how the compounded value is calculated after using the compound interest formula.
