Debt Consolidation Calculator (Canada)
This debt consolidation calculator for Canada blends up to four debts and compares them with one loan, showing the monthly saving and interest saved.

What it does
The Debt Consolidation Calculator combines up to four Canadian debts into one balance at their balance-weighted average rate, then compares that with a single consolidation loan at a new rate and term to show the monthly saving and total interest saved.
Data sources & parameters
This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.
We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
blended rate = sum(balance x rate) / sum(balance); monthly payment = P x i / (1 - (1 + i)^-n), where i = rate / 12 and n = term in months; saving = current payment - new payment
How it works
It adds your debt balances and works out the blended rate as the balance-weighted average of each debt's rate. It then amortizes the same total over the chosen term at both the blended rate and the new consolidation rate, and subtracts one result from the other.
Where it is used
- Checking whether a consolidation loan lowers the monthly payment
- Estimating the total interest saved by refinancing several debts
- Comparing a blended credit-card rate with a fixed loan offer
Worked example
Consolidating … of debt at a blended … into one loan at 10% over 48 months cuts the payment to … and saves … in interest.
Juggling several credit cards and loans is expensive and stressful, and consolidation is the usual way Canadians simplify it. Enter up to four debts with their balances and rates, then a consolidation loan rate and term, and the calculator reports the new monthly payment, the payment you are effectively making now, the monthly saving and the total interest saved.
How the calculator works
Enter each debt’s balance and rate, using the advanced fields for a third and fourth debt. The tool adds the balances and calculates the blended rate, the balance-weighted average of your rates. It then amortizes the total twice over the same term: at the blended rate, to approximate your current cost, and at the new rate. Comparing the two gives the saving per month and over the life of the loan.
Understanding the blended rate
If you owe $10,000 at 20%, $5,000 at 22% and $3,000 at 18%, the average is not the midpoint of the three rates, because the larger balances carry more weight. Multiply each balance by its rate, add the results and divide by the $18,000 total, and the blended rate is about 20.2%. That is the fair benchmark for any consolidation offer.
A worked example
Those same three debts, $18,000 at a blended 20.2%, against a consolidation loan at 10% over 48 months. At the blended rate the balance would cost about $549.88 a month; at 10% the payment is about $456.53. That saves about $93 a month and about $4,481 of interest over four years, and you would repay about $21,913 in total. The monthly saving is breathing room in the budget; the interest saving is the long-term gain. Because the term is the same in both cases, the $4,481 comes purely from the lower rate.
The trap of a longer term
The most common mistake is chasing a lower payment by stretching the term. A longer loan lowers the payment but can mean more interest overall, because you borrow for longer even at a lower rate. Change the term in the calculator and watch the total interest move. Aim for a payment you can sustain on the shortest term you can manage.
When consolidation makes sense
Consolidation works best when the new rate is clearly below your blended rate, when you can keep the paid-off cards at zero, and when the term is reasonable. It helps less if the new rate is only slightly lower, if fees eat the saving, or if the spending that created the debt continues.
Consolidation options available to Canadians
An unsecured consolidation loan or line of credit is the most common route and is priced on your credit profile. A home equity line of credit or a mortgage refinance usually carries a much lower rate because your property secures it, but it turns unsecured debt into debt against your home. A low-rate balance transfer card can work for smaller balances, but the promotional rate expires and the rate afterwards is high. For debt that consolidation cannot solve, licensed insolvency trustees and non-profit credit counsellors offer debt management plans and consumer proposals. Enter the quoted rate for the product you are actually offered.
Common mistakes to avoid
- Chasing the lowest payment by extending the term, which can raise total interest.
- Running the old cards back up, which leaves you with both the loan and new card balances.
- Ignoring fees. Setup costs, insurance or early repayment charges can eat a small saving, so compare the all-in cost.
- Securing debt against your home without weighing the risk. A HELOC or refinance lowers the rate but puts the property at risk if you cannot pay.
Planning tips for Canadians
Use a real quoted rate, try a couple of terms and pick the shortest your budget can carry, and check that the new rate is clearly below your blended rate before applying. Deal with the spending pattern that created the debt; consolidation only becomes a fresh start when that changes too.
Assumptions and limitations
This is a planning estimate. It amortizes the combined balance at the blended and the new rate over the same term, assumes constant rates, and leaves out setup fees, insurance and early repayment charges. It approximates your current cost with one amortizing schedule rather than tracking each debt’s own minimum payment. Use accurate statement rates and a genuine quoted loan rate, and treat the results as a guide rather than a loan offer.
