Line of Credit Calculator

There are many assumptions and simplifications built into the home equity line of credit calculator, so don't expect the amounts to match exactly with your bank. Due to the complexity of the spreadsheet, it wouldn't surprise me if the line of credit calculator contains errors. Please do report an error if you suspect there may be one, but don't expect the calculations to match exactly.

Read the Cell Comments: Most of what you may need to know about the line of credit calculator can be found by reading the comments identified by the little red triangles in many of the cells.

Tracking Payments: You can manually enter the Payment Date, Interest Rate, and Payment within the table if you want to track your actual payments, by overwriting the formulas. If you do that, you should probably highlight those cells so that you can identify that they no longer contain formulas.

Variable Rate Simulation: This feature of the line of credit calculator is not meant to try to predict future rates. Rather, it is designed to help you simulate what might happen if rates increase or fall. The Random Rate Change option can be fun to play with. Press F9 repeatedly to watch how values change.
