How Long Will It Take to Pay Off Debt?

Payoff timelines by debt level

$5,000 debt at 20% APR

• $100/month → never paid off (interest exceeds payment)
• $200/month → 33 months, $1,560 interest
• $300/month → 19 months, $890 interest
• $500/month → 12 months, $530 interest

$10,000 debt at 20% APR

• $200/month → barely paying down (mostly interest)
• $300/month → 51 months, $5,170 interest
• $500/month → 25 months, $2,360 interest
• $1,000/month → 11 months, $1,025 interest

$25,000 debt at 18% APR

• $500/month → 90 months (7.5 years), $20,200 interest
• $750/month → 47 months, $9,930 interest
• $1,000/month → 32 months, $6,490 interest

Why higher monthly payments save so much

Doubling your monthly payment usually less than doubles the speed but more than halves the total interest. Every extra dollar attacks the principal directly, after the interest portion is covered.

How APR changes the timeline

Same $10,000 balance, $300/month payment:

• 6% APR (personal loan): 37 months, $1,100 interest
• 12% APR (lower-rate card): 41 months, $2,250 interest
• 20% APR (typical card): 51 months, $5,170 interest
• 28% APR (store card): 73 months, $11,950 interest

Refinancing $10K from a 22% credit card to a 10% personal loan can save 18+ months and $3,000+ in interest.

Strategies that shrink the timeline

1. Cut spending temporarily and throw the savings at the highest-APR debt.
2. Sell anything you don't need — every $500 lump sum cuts months off the back end.
3. Use a 0% balance transfer card to freeze interest for 12–21 months.
4. Consolidate multiple cards into one personal loan at a lower fixed rate.
5. Make biweekly payments instead of monthly — adds one extra payment a year.

Payoff time by monthly payment

Going from $250 to $350 halves the timeline and removes almost $7,000 of interest. That $100 is the single highest-return change available to most households.

Worked example: finding the extra $100

• Cancel two unused subscriptions: $34/month
• Move one weekly takeaway to a home-cooked meal: $48/month
• Switch to a cheaper phone plan: $22/month

That is $104 a month with no income change — and on the table above it removes four years of repayments. Confirm the effect for your own balances with the debt snowball calculator.

Related questions

Why do minimum payments take so long?

Minimums are usually 1–3% of the balance, so they shrink as the balance shrinks — stretching a payoff over decades. See minimum payment vs extra payment.

Should I consolidate to speed things up?

Only if the new rate is genuinely lower and you do not re-run the balances. Trade-offs in debt consolidation explained.

Does paying weekly instead of monthly help?

Slightly on revolving debt, because of the average daily balance. On instalment loans, extra principal matters more than timing.

Key takeaways

• Payoff time is driven mainly by the payment above the minimum.
• On a $12,000 balance at 19.9%, an extra $100/month can halve the timeline.
• Keep the payment fixed as balances fall instead of letting minimums shrink.
• Model your exact set of debts before choosing a strategy.
