New Year’s resolution 2027: take stock of your debts in 4 steps
How much do your debts really cost you each month? A 4-step method to list everything, calculate the interest and know what to repay first.

In brief
Taking stock of your debts means listing everything, finding the real rate, calculating the month’s interest and choosing a repayment priority. An hour of work is often enough to find out what your debts really cost you, and where to start.
January is the month of New Year’s resolutions, and also of credit card statements. If you feel your debts never go down, the first thing to do is to take stock of your debts. Not to judge yourself, but to know exactly where you stand.
You wouldn’t be alone: at the end of 2025, Canadian households owed an average of about $1.77 for every dollar of disposable income (the money left after taxes), according to Statistics Canada data analyzed by the Royal Bank of Canada (RBC)1.
Here’s a four-step method. Set aside an hour, your statements and a sheet of paper or an Excel file.
The number to remember
1 hour
That’s all it takes to take stock of your debts and find out what they really cost you. Shall we start?
The method at a glance
- List everything: every debt, without exception, with its balance and its payment.
- Find the real rate: the one on the statement or the contract.
- Calculate the cost: the interest each debt costs you every month.
- Choose a priority: which debt to repay first.
Step 1: list everything, without exception

Write each debt on one line, with four pieces of information: the balance, the interest rate, the monthly payment and the end date, if there is one.
Don’t forget the debts we tend to forget:
- store cards and “buy now, pay later” purchases;
- the line of credit, even if you “almost never” touch it;
- the car loan or a long-term car lease;
- personal loans, including those from a relative;
- taxes owed to the Canada Revenue Agency (CRA) or Revenu Québec.
Step 2: find the real rate on each debt
The rate is on your statement or your contract.
According to Protégez-vous2, the going rate on a credit card is between 19% and 21%. If one of your debts is above that, highlight it.
Step 3: calculate what your debts cost you each month
For each debt, take the two figures noted in steps 1 and 2: the balance and the annual rate. The calculation is done in two stages.
1. The year’s interest = balance × annual rate. Example: $6,000 on a card at 19.99% → $6,000 × 19.99% = about $1,199 in interest a year.
2. The month’s interest = the year’s interest ÷ 12. Example: $1,199 ÷ 12 = about $100 in interest a month.
It’s an approximation: banks calculate card interest every day, and the balance changes from one month to the next. But the order of magnitude is right, and that’s what matters for taking stock.
Then compare that interest with your monthly payment, meaning the amount you actually pay each month, shown on your statement or contract.
3. The share of the payment that goes to interest = the month’s interest ÷ monthly payment. Example: you pay $180 a month on this card → $100 ÷ $180 = about 56%. In other words, of each $180 payment, about $100 pays the interest and only $80 actually reduces the debt.
Here is the complete illustrative example of a household with four debts:
| Debt | Balance | Annual rate | Year’s interest | Month’s interest | Monthly payment | Share going to interest |
|---|---|---|---|---|---|---|
| Credit card | $6,000 | 19.99% | $1,199 | $100 | $180 | 56% |
| Store card | $2,000 | 29.99% | $600 | $50 | $100 | 50% |
| Line of credit | $10,000 | 7.5% | $750 | $63 | $250 | 25% |
| Car loan | $15,000 | 8.99% | $1,349 | $112 | $390 | 29% |
| Total | $33,000 | $3,898 | $325 | $920 | 35% |
This table reveals three things:
- This household pays about $3,900 in interest a year, or $325 a month.
- Of $920 in monthly payments, 35% goes to interest, more than a third.
- On the two cards, half the payment or more only pays the interest. Those are the debts that “never go down.”
Illustrative example. Month’s interest = balance × annual rate ÷ 12.
View the data
| Debt | Monthly payment | Interest | What repays the debt |
|---|---|---|---|
| Credit card | $180 | $100 | $80 |
| Store card | $100 | $50 | $50 |
| Line of credit | $250 | $63 | $187 |
| Car loan | $390 | $112 | $278 |
Do the same calculation with your own numbers. The total of the month’s interest and the share going to interest are often the most telling figures of the whole exercise.
Step 4: which debt should you repay first?
A basic rule: keep paying at least the minimum on all your debts, to avoid fees and damage to your credit file, meaning the record of your repayments that lenders look at. Then put every extra dollar toward a single debt. Two methods have proven themselves:
- The avalanche method: you repay the debt with the highest rate first, here the store card, then the credit card. It’s the method that saves the most interest.
- The snowball method: you repay the smallest balance first, here again the store card ($2,000), then the credit card ($6,000). Quick wins help you stay motivated.
When a debt is repaid, its payment is added to the next one, and the effect speeds up.

What next?
Your review gives you a clear picture of the situation. Depending on what it shows, several paths are possible:
- If the interest stays reasonable, the repayment plan from step 4 and a tight budget may be enough.
- If a large part of your payments goes to interest, it’s worth exploring other options. For a homeowner, bringing high-rate debts into the mortgage (that is, increasing the mortgage loan to repay your other debts and having just one payment, at a lower rate) can reduce monthly payments. But stretching out the repayment period can also increase the total interest paid: each situation has to be looked at case by case. See our page on debt consolidation.
- If the situation seems unmanageable, the ACEFs (family economics cooperative associations), which are community organizations, offer free, confidential budget consultations across Quebec. 211 (opens in a new tab) will point you to the nearest one.
Your debts also affect your borrowing capacity, meaning the amount a lender would agree to lend you: our article on how to determine your borrowing capacity explains how lenders take them into account.

Frequently asked questions
How do you calculate the monthly interest on a debt?
Multiply the balance by the annual rate, then divide by 12. For example, $6,000 at 19.99% gives about $100 in interest a month. It’s an approximation good enough for taking stock.
Which debt should you repay first?
The avalanche method targets the debt with the highest rate first, which cuts interest the most. The snowball method targets the smallest balance, which gives quick wins. In both cases, you keep paying the minimum on all your other debts.
How do you know if your debts have become too heavy?
A clear signal: a large part of your payments only covers the interest, and the balances hardly go down anymore. In that case, it’s worth talking to a professional.
