The same $42 fee on a $300 payday loan is 730% APR when the loan runs 7 days and 82% APR when it runs 62 days, and a $10 NSF fee works out to anywhere from 12% to 4,867% APR depending on the size of the bounced payment and how fast it’s covered. The dollars never move. APR annualizes a cost, it doesn’t measure one, so for money borrowed for days rather than years the useful comparison is dollars out of pocket first and dollars per $100 per week second. This article runs that arithmetic on Canada’s 2026 caps: $14 per $100 on a payday loan, $10 for a bank NSF fee, and a flat $5 wage advance fee.
Key Takeaways
- The same $42 fee on a $300 payday loan is 730% APR over 7 days and 82% APR over 62 days. The borrower pays $42 in both cases.
- A $10 NSF fee on a $50 payment covered in 7 days is 1,043% APR. The same $10 on $1,000 covered in 30 days is 12%, an 86-fold gap for identical dollars.
- At the extreme, a $10 NSF fee on a $25 payment covered in 3 days is 4,867% APR, about 139 times the 35% criminal rate of interest.
- A flat $5 fee costs more per dollar than a $14-per-$100 payday loan on any advance under $35.71. At $300 the payday loan costs 8.4 times as much.
- A $50 flat-fee advance repaid the next day is 3,650% APR. It costs $5.
- Measured as dollars per $100 per week, the nine products in Table 4 run from $0.17 to $20.00, a unit you can set against your bank balance.
This article reflects the federal and provincial rules on payday loan costs and bank NSF fees as of September 2026. The criminal interest rate, the $14 per $100 payday cap and the $10 NSF cap can all change. Check the Financial Consumer Agency of Canada and your own loan or account agreement for current details.
How APR Is Calculated for Short-Term Money
Divide the fee by the amount advanced, then multiply by the number of times the term fits into a year. No compounding. In symbols: APR = fee / principal x 365 / days. At the payday cap, $14 / $100 is 0.14. A year holds 365 / 14 = 26.07 fourteen-day periods, and 0.14 times 26.07 is 3.65, or 365%. Consumer Protection BC tells licensees that a 14-day loan at the maximum cost “will have an APR of 365.00%”. The Financial Consumer Agency of Canada gives the same example on $300: $42, “approximately 365%”.
Disclosure puts every credit product, from a 25-year mortgage to a two-week loan, on one scale, and one scale is what makes it enforceable. The scale was built for money held for years. The trouble starts when it’s read as a price for money held for days.
The Same $42 Is 730% or 82%
In a designated province a payday lender may charge at most $14 per $100 advanced, whatever the term. On $300 that’s $42. Table 1 holds the fee fixed and moves only the term.
| Term | Cost on $300 | APR |
|---|---|---|
| 7 days | $42 | 730% |
| 14 days | $42 | 365% |
| 30 days | $42 | 170% |
| 62 days | $42 | 82% |
The borrower pays $42 in every row. The rate falls from 730% to 82% because the same $42 is spread across more days. By APR, the 62-day loan is less than a quarter as expensive as the 14-day loan. By the bank statement they’re identical.
The $10 That Ranges From 12% to 4,867%
Since March 12, 2026, a bank may charge at most $10 for a non-sufficient-funds event on a personal deposit account. An NSF fee isn’t a loan; nobody advanced the money. Economically it’s the price of being short by an amount for the days until it’s covered, the same event as borrowing that amount for that long. Table 2 applies the formula to a $10 fee.
| Bounced payment | Covered in 3 days | 7 days | 14 days | 30 days |
|---|---|---|---|---|
| $25 | 4,867% | 2,086% | 1,043% | 487% |
| $50 | 2,433% | 1,043% | 521% | 243% |
| $100 | 1,217% | 521% | 261% | 122% |
| $250 | 487% | 209% | 104% | 49% |
| $500 | 243% | 104% | 52% | 24% |
| $1,000 | 122% | 52% | 26% | 12% |
Read the corners. $10 on a $25 payment covered in three days is 4,867% APR. The same $10 on $1,000 covered in 30 days is 12%, below a typical credit card purchase rate. Two cells closer to everyday life, $50 in 7 days against $1,000 in 30 days, still give 1,043% against 12%: 86 times, for a fee that’s $10 in both. No bank changed its price between those cells. The customer changed the denominator.
The table leaves two things out. The $10 cap binds the bank only. The payee whose payment bounced may add its own returned-payment charge, and a payday lender may charge a dishonoured-payment fee where its province allows one ($20 in BC and Ontario). And the cap covers banks and federal credit unions on personal accounts only. Either pushes the cost of a bounce above $10 and moves every cell up.
The Flat Fee Is Not Free Either
A flat fee behaves the same way. NotchUp charges one, a flat $5 with no interest on a standard advance, so Table 3 moves a $5 wage advance fee across amounts and days until payday. (The Is NotchUp legit page covers the licence and how the advance works.)
| Advance | 1 day | 3 days | 7 days | 14 days |
|---|---|---|---|---|
| $50 | 3,650% | 1,217% | 521% | 261% |
| $100 | 1,825% | 608% | 261% | 130% |
| $250 | 730% | 243% | 104% | 52% |
| $500 | 365% | 122% | 52% | 26% |
| $1,000 | 182% | 61% | 26% | 13% |
| $1,500 | 122% | 41% | 17% | 9% |
A $50 advance taken the day before payday is 3,650% APR. It costs $5. That cell is ten times the payday loan’s headline figure, for the same reason the NSF table exploded: fixed dollars divided by a small amount and a short term.
There’s also a crossover. A payday loan at the cap costs 14 cents per dollar. A $5 flat fee costs 14 cents per dollar at exactly $35.71 (5 divided by 0.14). Below that the flat fee is the more expensive product per dollar: a $25 advance for $5 is 20 cents per dollar, against $3.50 from a payday lender. Above about $36 it reverses, and at $300 the payday loan’s $42 is 8.4 times the flat fee. Which is cheaper depends on how much is borrowed, and no single APR for either product would have said so.
One caution the table can’t show. An advance covers a timing gap between a bill and a paycheque. It isn’t a fix for an ongoing budget shortfall, and $5 on a $25 gap is real money.
A Metric That Does Not Explode: Dollars per $100 per Week
A better scale for short money should compare products of different sizes and terms on one footing and return numbers a person can picture. Dollars per $100 per week does both: divide the fee by the amount in hundreds, then by the term in weeks. Table 4 applies it to the products above plus two credit card cases.
| Product | Amount | Term | Fee | Cost per $100 per week | APR |
|---|---|---|---|---|---|
| Payday loan (at cap) | $300 | 14 days | $42.00 | $7.00 | 365% |
| Payday loan (at cap) | $300 | 62 days | $42.00 | $1.58 | 82% |
| NSF fee on a bounced payment | $50 | 7 days | $10.00 | $20.00 | 1,043% |
| NSF fee on a bounced payment | $500 | 30 days | $10.00 | $0.47 | 24% |
| Flat-fee wage advance | $50 | 7 days | $5.00 | $10.00 | 521% |
| Flat-fee wage advance | $300 | 14 days | $5.00 | $0.83 | 43% |
| Flat-fee wage advance | $1,500 | 14 days | $5.00 | $0.17 | 9% |
| Credit card cash advance (22.99% plus assumed $5 fee) | $300 | 14 days | $7.65 | $1.28 | 66% |
| Credit card purchase carried (19.99%) | $300 | 30 days | $4.93 | $0.38 | 20% |
The metric still ranks the small, short cases as the dear ones: a $10 NSF fee on $50 is $20 per $100 per week, and a $5 fee on a $50 advance is $10. It says so in dollars and doesn’t multiply by 52. Set $7.00 beside $0.83 and the 8.4-fold gap from the crossover is there, in a unit a bank balance shares.
It has limits. It’s still a rate, so $5 on $50 and $100 on $1,000 both read $10 per $100 per week, and it says nothing about what happens if you miss the repayment.
Why the Number Behaves This Way
For any fixed fee, APR is inversely proportional to amount times days. Halve the amount and APR doubles. Halve the days and it doubles again. Interest-bearing products don’t behave like this: their charge grows with amount and term, so the effects cancel and APR stays put. A fixed fee has nothing to cancel against.
One worked case. A $5 fee on a $50 advance repaid in two days: 5 / 50 = 0.10, times 365 / 2 = 182.5, gives 1,825% APR. A $50 payday loan for 14 days at the cap costs $7 and discloses at 365%. By APR the flat fee is five times worse. By the wallet it’s $2 cheaper. APR answers what the money would cost if it ran for a year at this pace. The wallet answers what it will cost. For a mortgage the two questions share an answer. For a three-day gap between a bill and a paycheque they come apart.
What the Law Caps
Since January 1, 2025, section 347 of the Criminal Code sets the criminal rate of interest at 35% APR. Before that it was 60% EAR, roughly 48% as an APR. Payday loans are exempt only in provinces with a designated regime, where the Criminal Interest Rate Regulations (SOR/2024-114) cap the cost at 14% of the amount advanced, $14 per $100. Nine provinces are designated, every province except Quebec. Quebec and the three territories have no designated regime, so a payday loan there falls under the 35% criminal rate. The payday loan guide covers provincial licensing.
Since March 12, 2026, under section 10.1 of the Financial Consumer Protection Framework Regulations (added by SOR/2025-96), a bank may charge a natural person no more than $10 for a non-sufficient-funds event on a personal deposit account, not more than once in a period of two business days for the same account, and not at all when the account is in unauthorized overdraft by less than $10. There is no grace period to cover the shortfall before the fee applies. The cap binds banks and federal credit unions, personal accounts only. Before the cap, FCAC says NSF fees typically ran $45 to $48.
A payday lender’s dishonoured-payment fee is set by the province, not Ottawa. BC and Ontario allow $20. The federal regulations leave a provincially authorized fee out of the 14% cap only up to $20, so $20 is where the fee sits in practice. Our NSF fee page lists what each bank charges.
How To Compare a Short-Term Cost in 30 Seconds
Count the dollars out of pocket, including any fee the payee adds if a payment bounces. If two options are close, divide each fee by the amount in hundreds and by the term in weeks, and compare dollars per $100 per week. Look at APR last, for what it’s good at: ranking products held for months or years, such as the card balances in the minimum payment map. If the first step settles it, stop there. The list of payday loan alternatives applies this order to each option available in Canada.
Methodology and Disclosure
Every APR here uses the formula above, simple and without compounding, the method Consumer Protection BC and FCAC use for payday disclosure, rounded to the nearest whole percent. Table 2 treats an NSF event as a loan of the bounced amount for the days until it’s covered, an analytical assumption since a bounce is a penalty rather than a credit agreement. $10 is the federal bank cap, not a survey of charges. Table 4’s card rows assume 22.99% on a cash advance with an assumed $5 fee and 19.99% on a carried purchase. Payday rows use the $14-per-$100 cap. NotchUp offers a flat-fee wage advance and isn’t a neutral party; every cell is reproducible from the formula. Computed September 15, 2026.
Frequently Asked Questions
Why is the APR on a payday loan so high?
The APR on a payday loan is high because the fee is fixed and the term is short. The maximum charge is $14 per $100, or 14%, and a 14-day term fits into a year 26 times; 14% times 26 is about 365%. The same $42 on $300 would disclose at 82% over 62 days.
What is the maximum payday loan cost in Canada?
The maximum payday loan cost in Canada is $14 per $100 advanced in the nine designated provinces (every province except Quebec), under federal regulations in force since January 1, 2025. A province may also allow a dishonoured-payment fee, $20 in BC and Ontario. In Quebec and the territories the 35% criminal rate applies.
Is a $10 NSF fee really 1,000% APR?
A $10 NSF fee can be 1,000% APR, and it can also be 12%. A $10 fee on a $50 payment covered in a week is 1,043% by the disclosure formula; the same fee on $1,000 covered in a month is 12%. No APR is disclosed for an NSF charge because it’s a penalty rather than a loan, but the arithmetic is the same as for any fixed fee.
Can my bank charge me two NSF fees in the same week?
A bank can charge you more than one NSF fee in a week, but not more than one in any two business days on the same personal account, and never more than $10 each, under the federal rules in force since March 12, 2026. Two bounced payments four days apart can still cost $20. The payee’s own returned-payment charge is separate and isn’t capped by these rules.
What is the criminal interest rate in Canada?
The criminal interest rate in Canada is 35% APR under section 347 of the Criminal Code, since January 1, 2025. Before that it was 60% EAR, roughly 48% as an APR. Payday loans in designated provinces are exempt and capped at $14 per $100 instead.
Is a $5 flat fee cheaper than a payday loan?
A $5 flat fee is cheaper than a payday loan at the $14-per-$100 cap on any amount above $35.71, and more expensive per dollar below it. On $300 the payday loan costs $42 against $5. On $25 the flat fee is 20 cents per dollar against 14 cents. Compare the dollars for the amount you actually need, not the APR.
What is the best way to compare short-term borrowing costs?
The best way to compare short-term borrowing costs is to count the dollars first, including any returned-payment charge from the payee. If two options are close, compare dollars per $100 per week, which scales for size and term without annualizing. Use APR last, for products held for months or longer.
