Bear with me...
To not display zero values on a sheet, the usual method works- go File/Options/Advanced/ then down to "Display Options for this worksheet" and uncheck "Show a zero in cells that have zero value". Click OK.
In your sheet, that appears to do nothing (where $0.00 shows) but if you change the format of those cells to General. you'll see they have tiny non-zero values e.g. in cell D698 it's 0.000146644 and in D699 it's 1.51304E-07 (showing in Engineering notation and equivalent 1.513 /10,000,000). Overtype with zero and the cell will appear empty.
I guess your options are to check your workings to ensure a true zero value is reached or use conditional formatting for where the value is less than 0.01, the font is white. (That's suggest in the Microsoft guidance Display or hide zero values).
You could change your formula in A712 to
=IF(D711<=0.01,"",A711+1)
That will blank A712 but mess up your other cells e.g. M to Q (giving #VALUE errors).
A quick fix for that is to use Conditional Formatting (and ISERROR based on each cell) to set both cell fill and font to white- see attached file where that's done for A17:T1000 of Amort.
Hope this helps.
