What this actually means
Minimum payments are designed to be slow
A 2% minimum on $5,000 barely outruns 22% interest. That is why 137 months of payments end up costing $8,678 in interest alone.
Every extra dollar earns 22, guaranteed
Paying down a 22% card is a risk-free 22% return. No investment offers that reliably — which is why debt payoff beats investing at these rates.
The tipping point
Your $500 extra shortens the loan by 127 months. Doubling it to $1,000 clears the balance in 5 months.
What if you changed the number?
Same habit, different size. Each one is a full simulation of its own.
Frequently asked questions
How long to pay off $5,000 paying $500 extra a month?
About 10 months (0.8 years), versus 137 months on minimum payments only.
How much interest does the extra payment save?
$8,202 — about 4.8 months of median US rent — and you finish 127 months earlier.
Should I invest that money instead?
At 22% card interest, almost never. You would need to beat 22% after tax, every year, with certainty. Pay the card first, then invest.
