The Debt Destroyer Is Quietly Costing You $42,000 a Year — and 8 Out of 10 Canadian Business Owners Have No Idea They’re Being Eaten Alive by Bad Interest

If you’ve ever looked at your business bank statement and thought, “I’m profitable but I feel broke,” this is the paragraph that explains why.

Let me start with a number that will make you put down your coffee. The average Canadian business credit card charges 19.99% interest. The average secured business line of credit charges 3.5% to 6%. The average Canada Revenue Agency interest rate on overdue taxes is 9%. And the average unsecured business loan from a big bank sits around 7% to 10% — if you qualify.

If you carry a balance of just $40,000 on a piece of plastic charging 20%, you are paying $8,000 a year in interest. That is a second car payment. That is a TFSA contribution you will never get back. That is the Debt Destroyer — one of the 7 Destroyers of Wealth — operating silently inside your own business, and it is eating the Earn, Save, and Grow rooms of your Financial House at the same time.

Most business owners don’t even notice because the payments are automated, the statements are digital, and the “minimum payment due” checkbox is the easiest click on the page. The bank is not going to send you a letter that says, “Hey, you could be saving $7,600 a year by switching to a secured line.” The bank makes its profit on the 20%. Your job is to see the trap before the trap sees your retirement.

The $42,000 Math Problem: Why Your “Convenient” Debt Is a Wealth Incinerator

Let’s make this concrete. I’m not going to lecture you about avoiding debt — debt is a tool, and every business owner I know has used it to grow. The question is not whether you use debt. The question is what kind, and at what rate.

Here is the comparison that counts. Assume you are carrying $50,000 in total debt across your business and personal life — a mix of credit cards, lines of credit, and maybe a car loan.

Debt Type	Rate	Annual Interest	5-Year Cost
Credit card (average)	19.99%	$9,995	$57,141
Unsecured LOC	9%	$4,500	$25,726
Secured LOC / HELOC	5%	$2,500	$14,294
Mortgage refinance	3.5%	$1,750	$10,007

The difference between 19.99% and 3.5% on the same $50,000 is $8,245 a year. Over five years, that is more than $42,000 in interest that the bank collected instead of you. That is an RESP for one child. That is a fully funded TFSA. That is the equivalent of a 10% across-the-board revenue increase — without selling a single additional client.

Now pause and ask yourself honestly: how much of your business debt is at 5% or less — and how much is floating in the 10% to 20% zone? That gap is the Debt Destroyer’s feeding ground.

The 4 Traps That Keep Business Owners Stuck in Bad Debt

I have sat across the desk from dozens of Canadian business owners who are doing $500,000, $1 million, $2 million in revenue — and carrying credit card balances they haven’t touched in three years. Every single one fell into one of these four traps. See if you recognize yours.

Trap #1: “I’ll pay it off when revenue comes in”

This is the most expensive sentence in the English language for an entrepreneur. Revenue always comes. But a new expense also comes — a tool subscription, a contractor invoice, a tax instalment. The credit card balance becomes a permanent fixture. A StatCan survey of Canadian SMEs found that 42% of small businesses carry credit card debt month-to-month, and the average balance among those who do is $27,000. At 20%, that is $5,400 in preventable interest. A permanent fixture with a revolving cost.

Trap #2: “The points make it worth it”

I am going to say something your banker will never say out loud: the points are a lie. The average business credit card rewards program returns about 1% to 2% in value. If you carry a balance for even one month, the 20% interest wipes out your rewards for the next ten years. You are essentially paying $20 in interest to earn $1 back — and the bank is betting you’ll miss the math because the statement shows only the reward balance, not the interest you just paid to earn it. If you pay your balance in full every month, fine — use the points. If you ever carry a balance, cut the card and use a debit card or secured line instead.

Trap #3: “I grew into my credit limit”

This is the quiet one. Two years ago, a $20,000 credit limit felt enormous. Now you’re using $35,000 on a $50,000 limit, and it feels normal because revenue also grew. But the debt grew faster than revenue, because debt compounds — and your revenue doesn’t. That is the signature of the Debt Destroyer: it sneaks in through the back door of “this is just how business works.” It is not how business works. It is how banks make a 20% return on your cash flow.

Trap #4: “My accountant said the interest is tax-deductible”

This one drives me insane — because it’s true, and it makes you feel smart while doing something financially destructive. Yes, interest on business loans is tax-deductible. But deducting a dollar of interest only saves you 27 to 47 cents in tax (depending on your province and bracket). You are still losing 53 to 73 cents of every interest dollar you pay. The tax deduction is not a reason to carry high-interest debt. It is a cope — and the CRA is not your partner in paying 20% interest.

The Debt Flipping System: 4 Steps to Go From the Debt Destroyer to the Debt Builder

The goal is not to live debt-free. The goal is to own the spread — borrow at 3% to 5% and invest the difference in assets that return 7% to 10% or more. That is what the wealthy do. That is the Debt Builder, not the Debt Destroyer. Here is exactly how you flip the switch.

Step 1: Audit your actual rates (not your guesses)

Pull your last statement for every credit product you own — business credit cards, personal cards, lines of credit, car loans, equipment financing. Write down the annual interest rate on each one, not the monthly or the “effective rate.” Rank them from highest to lowest. I guarantee you will find at least one account charging more than 12% that you forgot existed.

Step 2: Kill the 20% zone first — before you invest another dollar

This violates every instinct a growth-minded entrepreneur has, because it feels like you’re treading water instead of building. But here is the math: paying off a credit card at 19.99% is the equivalent of earning a guaranteed, after-tax, risk-free return of 19.99%. No stock, no real estate deal, no business investment gives you that certainty. The only exception is your emergency fund — keep three months of expenses in cash before you attack the debt. After that, every extra dollar goes to the highest-rate balance.

Step 3: Refinance the rest — force the bank to compete

Once the 20% debt is gone, you have a clean balance sheet. Now you negotiate. Call your bank and ask for a secured business line of credit tied to your receivables or equipment. If you own a home, a HELOC at prime + 0.5% to 1% is your cheapest option. If you have $10,000+ in retained earnings inside your corporation, consider whether it makes sense to use corporate cash to pay down debt and then re-borrow from the company — structure it properly with your accountant, but the rate is whatever you set (we covered corporate cash strategies here).

The target: every dollar of business debt at 5% or less. Not 8%. Not 10%. Five or less. If your bank won’t give it to you, go to a credit union, a monoline lender, or a broker. They want your business. Make them earn it.

Step 4: Build a cash buffer so you never need bad debt again

This is the step that makes the system permanent. Set up a dedicated high-interest savings account (not your chequing account) and automate a monthly transfer — even $500 a month. In six months, you have $3,000. In 18 months, you have $9,000 plus interest. That buffer sits between your business and the credit card. An unexpected expense hits the buffer, not the 20% card. This one habit, more than any other, separates the business owners who build wealth from the ones who look wealthy while bleeding interest.

What $42,000 Actually Looks Like When You Flip It

Let’s close with the number that matters most — the one on the other side of this system.

You refinance your $50,000 in 20% debt down to 5%. The $8,250 a year you were paying in interest is now yours to redirect. You put it into a TFSA (we talked about why the TFSA is the most powerful tax shelter for business owners). Inside the TFSA, you invest it in a diversified growth portfolio averaging 7%.

Year 1: $8,250. Year 5: $49,000. Year 10: $122,000. Year 20: $362,000.

All tax-free. All from one decision: refusing to pay 20% for money you could get at 5%.

That is not theoretical. That is the difference between owning the spread and letting the bank own it for you. The Debt Destroyer becomes the Debt Builder when you flip the rate, and the same cash flow that was making the bank rich starts making you rich.

The Destroyer You Can’t See Is the One That Gets You

The 7 Destroyers of Wealth include procrastination, comparison, greed, and fear. But the Debt Destroyer is the most dangerous of all — because it looks like normal business. Every other owner you know carries a balance. The banks have designed their entire product suite around this being normal. Your statements are designed to be confusing. Your minimum payment is designed to be painless. Your rewards program is designed to distract you.

None of it is an accident. And none of it is your fault.

But it is your problem — and only you can fix it. The Financial House framework says Protect comes before Grow. And protecting yourself from the Debt Destroyer means knowing your rates, killing the 20% zone, refinancing the rest, and building a buffer so you never go back. That is the Protect room in action. Once it’s built, the Earn, Save, and Grow rooms start compounding the way they should — for you, not for the bank.
