Short answer
To pay off debt fast, stop new charges, find an extra monthly payment, and put all of it on one debt while paying minimums on the rest; when it is gone, roll that payment to the next. On $10,000 at 18%, paying $300 a month instead of $200 saves almost four years.
Why the extra payment matters more than anything else
Credit card interest is charged on the balance every month, so the minimum payment mostly feeds interest. A quick way to see it: balance × APR ÷ 12 is roughly the interest for one month. On a $10,000 card at 18% that is about $150 a month before a cent of the balance is repaid.
| Monthly payment on $10,000 at 18% | Paid off in | Total interest |
|---|---|---|
| $200 | 7 yr 10 mo | $8,622 |
| $250 | 5 yr 2 mo | $5,386 |
| $300 | 3 yr 11 mo | $3,967 |
| $400 | 2 yr 8 mo | $2,628 |
Our month-by-month calculation, interest at APR ÷ 12, fixed payment, no new charges. The St. Louis Fed, Page One Economics gives the $200 case as “more than seven years” and “over $8,000” in interest.
The first extra $100 a month cuts almost four years and more than $4,600 of interest. That is why every step below is about making the extra payment bigger and keeping it steady. The Financial Consumer Agency of Canada puts it the same way: additional and frequent payments mean you pay the debt off sooner and pay less interest.
Step 1. List every debt with what it costs per month
Write down each debt with four columns: balance, APR, minimum payment and monthly interest in dollars. Include cards, lines of credit, car and student loans, buy-now-pay-later plans and money owed to family. The dollar column shows where the money is going faster than any percentage does.
Step 2. Stop adding to the balances
Pay with debit or cash while you clear the cards. A card you pay down and keep using moves the balance in a circle. Remove saved cards from shopping sites and apps; our guide to stopping impulse spending covers the rest of that leak.
Step 3. Find the extra payment in your own numbers
- 01Start with what leaves automatically. Forgotten subscriptions and duplicate services are money nobody chose to spend this month. Cancelling them costs nothing in daily life. See subscription tracker apps.
- 02Take the two largest flexible categories. Total the last three months by category and trim the two biggest flexible ones, usually food out and shopping, for the payoff period only.
- 03Send irregular money straight to the target. Tax refunds, bonuses and side income go to the target debt the day they land, before they mix with everyday spending.
- 04Make it a budget line. Give the extra payment its own line in the budget so it is paid like rent, on payday. Budgeting while paying off debt shows the full layout.
Step 4. Choose one target and roll the payment
Pay minimums on everything and the whole extra amount on one target: the highest rate (avalanche, cheapest) or the smallest balance (snowball, first win sooner). The comparison with numbers is in debt snowball vs avalanche. When the target is paid off, its payment moves to the next target the same month.
Step 5. Lower the rate where you can
- 01Ask your card issuer for a lower rate. It is one phone call. A lower APR on the target debt shortens the plan without any change to your budget.
- 02Consider a balance transfer with care. A low promotional rate helps only if the balance is gone before the promotion ends. Read the transfer fee and the rate that applies afterwards, and keep the old card at zero.
- 03Consider consolidation with care. A single loan at a lower rate can replace several cards. It saves money only if the total cost is lower and the cards stay unused.
Step 6. Keep a small buffer while you pay
A car repair that goes on a card undoes months of work. Keep a small cash buffer while you pay down debt, then build a full emergency fund once the high-rate debt is gone. How much emergency fund you need depends on your fixed costs.

Find your extra payment in Finman
Import a bank statement file, see spending by category and the subscriptions it found, and track each debt as it falls. Free during the beta.
Find my extra paymentWhen paying faster is not the answer
If the minimums alone are more than you can pay, a faster plan will not hold. The Financial Consumer Agency of Canada describes two routes in Canada: a non-profit credit counselling agency that sets up a repayment program, and a consumer proposal prepared with a trustee licensed by the Office of the Superintendent of Bankruptcy. Talk to one before missing payments.
How Finman helps
Finman puts debts and spending in one web app. Import CSV, OFX or QFX bank files or type transactions in, sort them with your own category rules, and see which categories and subscriptions can fund the extra payment. Budgets warn you at 80% spent or when the current pace will break them before the period ends. Each debt keeps its balance, rate and due date; log payments to see what is left. Ask the AI CFO where the money went this month, and get a savings plan that suggests an order for your debts. Plans after the beta and what is free are on the pricing page.
Frequently asked questions
How can I pay off debt fast?
List every debt with its rate and monthly interest, stop adding new charges, find an extra monthly payment in your budget, and put all of it on one target debt while paying minimums on the rest. When the target is paid off, move its payment to the next debt.
How much faster does an extra $100 a month pay off debt?
On $10,000 at 18% APR, paying $300 a month instead of $200 clears the debt in 3 years 11 months instead of 7 years 10 months and cuts interest from about $8,622 to $3,967, by our month-by-month calculation.
Is it faster to pay the smallest debt or the highest interest debt first?
Paying the highest rate first (avalanche) is cheaper and usually finishes sooner. Paying the smallest balance first (snowball) closes an account sooner. In a St. Louis Fed example the avalanche finished three months sooner and saved $580.
Should I save money or pay off debt first?
Keep a small cash buffer so a surprise bill does not go on a card, then put extra money toward high-rate debt. Build the full emergency fund after the expensive debt is gone.
Does paying more than the minimum really help?
Yes. The Financial Consumer Agency of Canada notes that additional and frequent payments mean you pay off the debt sooner and pay less interest. Its example: $2,000 at 18% paid at $40 a month takes 7 years and 10 months.
What if I cannot afford my minimum payments?
Contact a non-profit credit counselling agency before missing payments. In Canada, a consumer proposal through a licensed trustee is another route the Financial Consumer Agency of Canada describes.
