Calculating Compound Interest in Power BI

Koen Verbeeck does the math:

Recently I had an interesting use case where I had to a compound calculation in Power BI. You can compound an interest rate for example, where you get a certain rate on your savings. Let’s say 1% (which is at the time of writing ridiculously high, but bear with me). After 1 year, you get 1% interest on your money. If you leave that (small) amount of money on your savings account, you’ll get 1% after another year on the original amount + the interest amount of the previous year. This means you’re money grows exponentially (sounds more exciting than it is in reality).

Read on for an example of creating what-if parameters around compound interest rates.
