It does exactly what I needed it to! Best and most effective app for its function!

I just purchased the NPV app. It’s straightforward to use. I hold a PhD in economics. I tested NPV’s calculations with four examples for which I computed the answer by hand. The app reproduced my computations exactly, suggesting the app’s calculations are correct. This app does a simple present value calculation correctly. It allows for any number of future payments and discounts the payments at a rate you choose. That’s exactly what I wanted. For what it does, this app is great and well worth the minimal cost. Strongly recommend for doing simple present value calculations.
