What this may mean for you
The trap isn't the minimum itself — it's that the minimum shrinks as you go. Freezing today's minimum as a fixed payment costs nothing extra this month and typically saves years. Issuer formulas vary (we model interest + 1% of the balance with a $25 floor); your statement's disclosure box shows your card's own version of this math.

Understanding this calculator
Minimum payments are engineered to keep balances alive: as the balance falls, so does the required payment, stretching a moderate balance into decades of interest. Your statement's disclosure box hints at this; this calculator shows the full picture and what any fixed payment does instead.
The escape is almost embarrassingly simple — freeze your payment at today's minimum instead of letting it decline. Same starting outlay, years faster, thousands cheaper.
Assumptions and methodology
- Models the common issuer minimum of interest + 1% of the balance, with a $25 floor (formulas vary by issuer).
- The comparison payment is fixed at the level you choose.
- Assumes no new charges and a constant APR.

Common questions
Why do minimums exist if they're so costly?
They keep accounts current at the lowest possible outlay — useful in a genuine emergency month, expensive as a habit. Treat the minimum as a floor for bad months, not a plan.
