The loan tenor could be in days, months and years. Thus, the rate of interest is converted accordingly before multiplying with the amount of the principal and tenor. The simple interest formula is Simple Interest = P*I*N. Here, P is the principal amount, the interest rate for the period and the tenor. What is the formula for compound interest? A = P (1+r/n) ^ (n*t)-1) Here, A = compound interest, P = principal amount, R = interest rate, N = the number of compounding periods and T = number of years (duration/tenor). What are the differences between compound interest and simple interest? The simple interest is the total amount paid to a borrower. It is for using the borrow money online over a fixed tenor. On the other hand, the compound interest earned on the interest on the earlier availed interest and even the principal amount.
