Pay this fixed amount every month and the $5,000 balance clears in three years. You will pay $1,874 in interest, saving $6,226 versus the minimum-only path.
The middle column locks the first month's minimum and never lets it shrink. The right column is the fixed monthly payment that clears the balance in three years. Both beat the minimum-only path by years.
Section II
The minimum payment is not a recommendation. It is the smallest amount your issuer will accept without marking the account late. As your balance falls, the minimum falls with it. Less goes to principal each month, more of every payment is interest, and the loan stretches across years that compound the bank's earnings while compressing yours.
