Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Payday loan fee | Total owed back |
|---|---|---|
| $500 · 15% fee | $75.00 | $575.00 |
| $1,000 · 15% | $150.00 | $1,150.00 |
| $300 · 20% (high-rate state) | $60.00 | $360.00 |
| $200 · 10% (capped state) | $20.00 | $220.00 |
How This Calculator Works
Enter the loan amount and the fee rate per $100 (US standard: $15 per $100 = 15%). The calculator multiplies the two to give the fee and shows the total owed back (principal + fee). A two-week $500 advance at the standard rate owes $575 in two weeks.
The Formula
Percentage Add-On
Rate is the tax or tip percentage applied to the amount
Worked Example
A $500 payday loan at the standard $15-per-$100 (15%) fee costs $75 in fees, for a total of $575 owed in two weeks. That fee structure annualizes to about 391% APR — far above any other consumer borrowing. Rolling the loan over because you can't repay in two weeks doubles the fee on the same $500. A few rollovers and the fees exceed the original loan.
Key Insight
Payday loan fees are presented as small per-period numbers ($15 per $100, sounds modest) but represent some of the highest effective APRs in consumer finance. A 391% APR loan is roughly 18x the rate of even a high-APR credit card. Credit-union small-dollar loans, employer pay advance programs, and even moderate-APR personal loans almost always beat payday lending on real cost. The only honest case for payday loans is when no other option exists — and even then, plan the exit aggressively.
Why payday APRs reach 400-700%
A $15 fee on $100 borrowed for 14 days seems modest until annualized. APR calculation: ($15 fee / $100 borrowed) × (365 days / 14 days) = 391% APR. At $20 fee: 521% APR. At $30 fee: 782% APR. The annualization is critical for honest comparison to other forms of credit.
Payday lenders argue annualization is misleading because loans are short-term, not annual. Critics argue annualization is the standard methodology used for all loan products under Truth in Lending Act, and the comparison is fair. The compromise: state regulators in some states cap effective annual rate at 36% (federal Military Lending Act standard for service members) regardless of state APR caps.
Cycle of debt: CFPB research found average payday borrower takes 8-10 loans per year. Each rollover involves new fees. A borrower starting with $300 borrowed at $20 fee per $100 ($60 total fees) often pays $600+ in annual fees on the same $300 principal — total cost exceeds 200% of borrowed amount within a year through rollovers.
Alternatives to payday loans
For consumers facing short-term cash needs, several alternatives offer dramatically better terms. (1) CREDIT UNION SMALL-DOLLAR LOANS (PALs) — National Credit Union Administration regulates these at maximum 28% APR. Available to credit union members.
(2) EMPLOYER CASH ADVANCES — many employers will advance future paychecks at no or minimal cost. Less stigmatized than payday loans; ask HR.
(3) NEGOTIATED PAYMENT PLANS — most U.S. utilities, medical providers, and landlords will negotiate payment plans rather than initiate collections. Calling and discussing usually produces a workable plan with no fees or much lower fees than payday.
(4) LOCAL CHARITABLE ASSISTANCE — community action agencies, churches, and 211 (United Way emergency assistance line) can provide one-time assistance for genuine emergencies. Limited but free.
(5) EARNED WAGE ACCESS — apps like Earnin, DailyPay, Even allow workers to access wages already earned but not yet paid. Some are free; some charge fees but dramatically lower than payday lending. Most major U.S. employers now offer EWA programs.
These alternatives don't always work for everyone or every situation, but most are dramatically better than payday lending for borrowers who can access them.
Payday loan effective APR by fee structure
Reference effective annual percentage rates for typical U.S. payday loan fee structures.
| Fee per $100 | Loan term | Effective APR | U.S. legal status |
|---|---|---|---|
| $15 | 14 days | 391% | Legal in 27 states |
| $20 | 14 days | 521% | Legal in some states; capped in others |
| $25 | 14 days | 651% | Common rate |
| $30 | 14 days | 782% | High-fee states |
| $15 | 30 days | 183% | Pawn loan/installment payday alternative |
| 12% APR (credit union PAL) | 30 days | 12% APR | NCUA cap; member access only |
| 36% APR (military / state caps) | any | 36% APR | Military Lending Act + 18 states |
| 0% APR (employer advance) | n/a | 0% | Best when available |
14 U.S. states + DC prohibit payday lending entirely. 18 states have effective 36% APR caps that make payday lending uneconomic. The remaining ~18 states permit triple-digit-APR payday lending with varying regulatory frameworks. Geographic disparity is dramatic: payday lending is uncommon in CT, NJ, NY, NC, MA; widespread in TX, MO, OH, IL where it's legal.
Frequently Asked Questions
How is a payday loan fee calculated?
Multiply the loan principal by the fee rate per $100. A $500 loan at $15 per $100 (15%) costs $75 in fees, for $575 owed back.
What APR does that translate to?
$15 per $100 (15%) over a two-week term annualizes to roughly 391% APR. ($15/$100) × 26 two-week periods per year = 390%. The fee structure makes the rate look small at the per-period level — annualized, it's enormous.
What happens if I can't repay in two weeks?
Most payday loans allow rollover — paying just the fee to extend another two weeks. Each rollover adds another full fee on the same principal. After 4 rollovers on a $500 loan, you've paid $300 in fees and still owe the $500. After 7, fees exceed the original loan.
Are payday loan rates capped?
By state. Some states cap APR at 36% (effectively banning payday loans). Many cap rates at $15 per $100 per pay period. Some have no effective cap. Online payday lenders sometimes operate from tribal jurisdictions that bypass state caps.
What are better alternatives?
Credit-union small-dollar loans (often capped at 28% APR), employer pay-advance programs (interest-free, deducted from next paycheck), credit card cash advance (high but lower APR than payday), or family/friend lending. All are typically far cheaper than payday loans even at their worst.
When is this calculator unreliable?
As a complete cost projection — single-loan APR calculation understates the systemic harm of the payday lending cycle. CFPB research suggests average borrower takes 8-10 loans per year, with cumulative fees often exceeding the original principal. For honest cost analysis, model the realistic possibility of repeated rollovers, which often produce total cost 200-400% of borrowed amount within 12 months.

Methodology & Review
Payday loan fee equals amount borrowed × fee rate. The calculator returns dollar fee and effective APR. U.S. payday loan fees typically $15-$30 per $100 borrowed for 2-week loan. $20 fee on $100 for 14 days = effective APR of 521% (computed: ($20/$100) × (365/14) = 521%). U.S. payday loans are heavily regulated at state level: some states cap APR at 36% (effectively banning payday lending); 14 states + DC prohibit payday lending entirely; many states regulate fees. RELIABILITY: Reliable for direct fee calculation. Less reliable as a complete cost picture because payday loans frequently roll over (borrower can't pay back, takes new loan to pay old) — research suggests average payday borrower takes 8-10 loans per year, with cumulative fees often exceeding original principal. Single-loan APR calculation understates the systemic harm of payday lending cycle.
