Understanding Compound Interest Calculation

Compound interest calculation is essential in finance. While Excel users can utilize the FV function, unfortunately, Power Apps or Power FX lacks a direct equivalent. However, you don’t need to worry! This article will explain how you can perform this calculation within Power Apps.

Let’s consider a scenario to put things into perspective:

Suppose you invest $100 for 5 years at a 2% interest rate, with the interest compounded monthly (12 times a year). 

You might refer to reliable online calculators, but this post will guide you on how to achieve the result using Power Apps, eliminating the need for external tools.

Compound Interest Formula Breakdown

Here’s the breakdown of the compound interest formula:

A = P(1+r/n)nt
  • A – Future value of the investment or loan.
  • P – Principal investment or loan amount.
  • r – Interest rate in decimal form.
  • n – Number of times interest is compounded per period.
  • t – Number of periods for which the money is invested.

Compound Interest in Power Apps

Now, let’s translate this formula into Power Apps:

    initialAmount: 100,
    annualRate: 0.02,
    timesCompounded: 12,
    totalPeriods: 5
    initialAmount * 
        Power((1 + (annualRate/timesCompounded)), (timesCompounded * totalPeriods))

Reference: With function

Within this formula:

  • initialAmount – Represents the principal investment/loan amount.
  • annualRate – Represents the interest rate (e.g., 2% is expressed as 0.02).
  • timesCompounded – Number of instances the interest is compounded within a period. (In the mentioned example, it’s 12 indicating monthly compounding.)
  • totalPeriods – Number of periods for which the investment is held (5 in the given scenario).

By running this expression within Power Apps, you should get the anticipated result of approximately $110.5


In conclusion, calculating compound interest within Power Apps should not intimidate you.
