Extra payments

The "Per month" amount is the one lever most worth playing with, see exactly how much sooner a bigger number gets you out of debt in "See the impact of paying more" below.

Strategy
Fixed total monthly payment?

Yes: once a debt is paid off, the payment that was going to it gets redirected to your remaining debts, so the total you're putting toward debt each month stays the same until everything's paid off. This is the faster, more standard way to run either strategy.
