Napkin math, done well.
Each tool answers one question quickly and admits what it is not asking. They are meant to start a conversation with your numbers, not finish one.
Maximum Collections Calculator
Theoretical maximum collections for your practice. Six inputs, one number.
Loan Extra Payment Calculator
Side-by-side cost-benefit analysis of extra principal payments.
Each calculator is intentionally narrow in scope. It tries to answer a simple question with as few inputs as possible to give a high-level response. It also attempts to name the things the napkin math leaves out: procedure mix, no-shows, the second half of any loan. The point is to give you a useful number quickly, and to make the difference between that number and your real one obvious.
