Track how much you already saved by paying extra on loans.
Quicken has a tool in mortgages that shows how much you would save by prepaying on the loan. For years, I have wanted a tool that shows you how much you have ALREADY saved by previous prepayments. A little graph showing the original loan payoff date vs. the current loan payoff date and the associated interest paid. It would let us give ourselves a little pat on the back and some positive reinforcement for paying down loans early. I have honestly not understood why this graph does exist as part of the graph for prepayment of the loan. It seems like it belongs there.
