The True Cost of Minimum Payments
How small payments cost you so much
In the last article, we covered the basics of credit cards.
Now let’s look at what happens if you don’t pay your balance in full.
Card issuers use different formulas, but the minimum payment is typically something like:
The greater of $25, or 1% of your balance + interest + fees
That sounds technical, but here’s what it means in practice:
Your minimum payment will be small — and a large portion of it goes toward interest, not reducing what you owe.
Your interest rate depends on your credit history, which we’ll cover in a future article.
If you’re just starting out as a young adult, lenders see you as more risky and charge higher rates — often in the 26-30% range. Even people with excellent credit typically pay around 18–20%.
For this example, we’ll assume an interest rate of 27.99%.
The Payment Math
Assume:
Beginning balance: $1,000
APR: 27.99%
No additional purchases or fees
Payments are made on time
The monthly interest rate is:
27.99% ÷ 12 = 2.3325%
Month 1
Beginning balance: $1,000
Interest: $1,000 × 2.3325% = $23.33
1% of balance: $1,000 × 1% = $10
Minimum payment: $23.33 + $10 = $33.33
Ending balance: $1,000 + $23.33 − $33.33 = $990
Month 2
Beginning balance: $990
Interest: $990 × 2.3325% = $23.09
1% of balance: $990 × 1% = $9.90
Minimum payment: $23.09 + $9.90 = $32.99
Ending balance: $990 + $23.09 − $32.99 = $980.10
Key Observation
Notice how little the balance decreases.
In the first two months, you paid $66.32, but your balance only went down by $19.90. Most of your payments go toward interest — especially early on.
Total Cost
If you continue making only the minimum payment:
It takes 80 months (6 years and 8 months) to pay off
You pay $1,137 in interest
That $1,000 balance turns into $2,137 total — more than double the original amount
It Gets Much Worse with Larger Balances
And the larger your balance, the worse this gets.
At $1,000, it takes 6 years and 8 months to pay off with minimum payments.
At $5,000, it takes over 20 years — and the total cost rises to $15,468, more than triple the original amount.
The Takeaway
Minimum payments are meant to keep you paying — not to get you out of debt.
They make the payment feel manageable, but they stretch repayment over years and dramatically increase the total cost.
Avoid this by following one simple rule:
Always pay your full statement balance every month.
If you can’t, pay as much as possible — and avoid adding new charges until the balance is paid off.
