How high-interest debt changes the cost of waiting
With high-interest debt, delaying repayment has a measurable cost because interest compounds on the unpaid balance. Illustrative calculations show that paying only minimums on a card balance can take years and cost a large share of the original amount in interest. These are illustrations, not personal advice.
Illustration: minimums only
Assumptions: 3,000 balance, 22% APR, minimum payment of 2% of balance or 25, whichever is higher, no new spending. Paying only the minimum can take well over a decade and cost several thousand in interest. Exact results vary by card terms.
Illustration: fixed extra payment
Same balance and rate, paying a fixed 150 per month: cleared in roughly two years with interest of around 700. Raising to 200 shortens it further. Fixed payments beat shrinking minimums.
Why waiting costs more
Monthly interest is roughly APR ÷ 12 of the balance. At 22%, that is about 1.8% per month — far above typical savings rates. Each month of delay adds interest on top of the existing balance.
Limits of these examples
Promotional rates, fees, changing APRs and new purchases all change the outcome. Use your own statement figures or a lender calculator.
Interpretation
Once a small emergency buffer exists, extra money directed at high-interest debt usually has a high effective return. This is general information, not individual advice.
Key Takeaways
- High APR makes delay expensive.
- Minimum payments stretch repayment for years.
- Fixed extra payments save substantial interest.
- Use your own statement figures.
