Open Question: Mortgage Spreadsheet Question?

I prefabricated a table consisting of month, payment, principal, interest, and unpaid columns. I institute the monthly commercialism using Excel's PMT (payment) calculator, and then manually place in the principal, welfare and unpaid values. However when I did this, there was a equilibrise of $0.04. I was wondering if there was a way to equilibrize this. Or if there are other Excel Functions for the principal, welfare values, and unpaid values. **Actual difficulty if you tending to look. $100,000 5 assemblage mortgage. 7% welfare evaluate per year, 0.5654145% per month. 60 coequal monthly payments. Thank you so much!
