Deb in WA, USA A good job as it would have been rather difficult from your original post, as Jay Lozier and Alan Gauld have pointed out. So please check this out http://sscce.org/ as it's a very handy reference. -- My fellow Pythonistas, ask not what our language can do for you, ask what you can do for our language.

We want to see the code - and order matters. output looks like this: Month: 1 Minimum monthly payment: 168 Remaining balance: 4111 You show the output but didn't show us how the output was produced. We had no chance of guessing what you were doing wrong. If you want help you need to help us by showing us the code. Don't guess at what might be wrong. If its less that, say, 100 lines post the real code and post any errors. Would any of you have a clue what could be wrong? Deb in WA, USA Not if you don't show us your code! > never mind.

In future post real code, real output and real errors.

Would any of you have a clue what could be wrong? Deb in WA, USA Deb, Can you show us your full code listing or if it is lengthy the relevant section showing the print statement. My guess is your print formating is not specified correctly and it is rounding to the nearest whole number.
