I have a mortgage right now and I am motivated to pay it off as fast as possible. I have thought of a few key performance indicators that I store in a spreadsheet and check on each month. These performance stats demonstrate how every little bit helps, and remind me to save for extra payments.
- Two simple ones are balance remaining and % ownership.
- Another simple one is interest to principal ratio, cumulative from the beginning of the loan to the present. I hate seeing all that money go to interest, so extra payments help me beef up the principal side.
- A more complicated KPI is days ahead of schedule. For example, right now I'm nearly 400 days ahead of the baseline (which is making minimum payments on a monthly basis).
- Finally, the last one I use is total interest saved. By making double-up and the odd lump sum pre-payment, I contribute directly to principal. For example, by getting to $130,000 balance 400 days sooner than baseline (minimum monthly payments), I have already saved nearly $4000 in interest.
I am curious to know what other measures or KPIs I can use to track my progress.
