Compound Interest Calculator is a ready-to-use excel template that helps to calculate compound interest with multiple compounding periods.
In addition to that, the template also provides a complete schedule of payments and interests accumulating each payment period.
What is Compound Interest?
Compound interest is the method of calculating interest any given amount assuming that the interest earned each period is added to the principal. Hence, you receive not only interest on your principal amount but also the added interest each year.
While calculating compound interest the compounding periods matter the most and have a significant difference. For example, the amount of 10% compound interest compounded annually will be lower than 5% compound interest compounded semi-annually over the same time period.
Formula To Calculate Compound Interest
Compound Interest (A) = P [(1 + i)n – 1]
Where: P = Principal Amount, i = interest rate, n = compounding periods.
