Ratings and reviews

This Compound interest calculator is excellent, and his has every option I am looking for including a year by year breakdown of your interest and contributions. Excellent job to the author(s) of this fine app.

No matter what I couldn't get the calculate button to be enabled, no error message nothing. It turns out, they won't allow you to use this to calculate retirement. You cannot have a negative contribution. What a pointless arbitrary restriction. Delete.

The calculations are not to the decimal point. Making sure the app doesn't round up would make this a great app. I do like that they break down each of interest earned.
