Regulators in Canada express the cost of a payday loan as an annual percentage rate. For a 14-day loan at the $14-per-$100 cap the figure is 365%, and it is quoted in nearly every article about payday lending in the country. It is correct. A $300 loan for 14 days costs $42, and $42 over 14 days annualizes to 365.00% by the formula Consumer Protection BC publishes for its licensees.
This piece asks a narrower question: what does that number measure when the amount is small and the term is short? We ran the regulators’ formula across a payday loan, a bank NSF fee, a flat-fee wage advance and a credit card. A fixed fee comes out anywhere from 9% to 4,867%, depending on nothing but the size of the loan and the number of days.
Computed September 15, 2026. Method and disclosures at the end.
Key Findings
- The same $42 fee on a $300 payday loan is 730% APR over 7 days and 82% APR over 62 days; the dollars never move.
- 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 difference 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.
- 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 and costs $5.
- Measured as dollars per $100 per week, the nine products in Table 4 run from $0.17 to $20.00, a unit a reader can set against a bank balance.
Key Takeaway
APR annualizes a cost; it does not measure one. For money borrowed for days rather than years, the same fee produces APRs that differ by a factor of several hundred, so the useful comparison is dollars out of pocket first and dollars per $100 per week second.
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; 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 is 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 is $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 are 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 account. An NSF fee is not a loan; nobody advanced the money. Economically it is the price of being short by an amount for the days until it is 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 is $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 in a designated province may charge up to $20 for a dishonoured payment. 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, so Table 3 moves a $5 wage advance fee across amounts and days until payday.
| 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 is 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.
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 does not 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 is 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 do not 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 is $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 SOR/2025-96 (Bank Act), 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 two business days for the same account, and not at all when the overdraft is under $10. There is no grace period. The cap binds banks and federal credit unions, personal accounts only. In designated provinces a payday lender’s dishonoured-payment fee may be at most $20. 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 is 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 is 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 is not 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?
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?
$14 per $100 advanced in the nine designated provinces (every province except Quebec), under federal regulations in force since January 1, 2025, plus a dishonoured-payment fee of at most $20. In Quebec and the territories the 35% criminal rate applies.
Is a $10 NSF fee really 1,000% APR?
It can be, 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 is a penalty rather than a loan, but the arithmetic is the same as for any fixed fee.
What is the criminal interest rate in Canada?
35% APR under section 347 of the Criminal Code, since January 1, 2025; before that, 60% EAR, roughly 48% as an APR. Payday loans in designated provinces are exempt and capped at $14 per $100 instead.
What is the best way to compare short-term borrowing costs?
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.
