A $300 payday advance costs $45 to borrow for two weeks in a typical 15% fee state, $52.50 in Alabama, about $9 for a full month in a 36% APR state, and roughly $5 to $25 on an app advance, which is why the state you borrow in matters as much as the amount. This guide walks the flat-fee math, the California exception, and what each regime does to the same $300, then prices the cheaper routes so the comparison lands in dollars rather than headlines.
The Flat-Fee Model
Most payday states price credit the way a check casher prices a service: a flat fee per $100 per term, typically $10 to $30, with 15% per $100 the most common. The arithmetic on $300 is the fee times three. At 15% per $100, that is $15 per hundred, $45 on $300, and a total repayment of $345 on your next payday, 14 days later. Annualized, $45 on $300 for 14 days is about 391% APR.
The APR and the fee answer different questions. The APR is a standardized number for comparing products across terms; the fee is what actually leaves your account. Per-$100 framing is also what makes shopping easy: whatever your state’s fee is per $100, multiply by three for a $300 advance, and you have the cost without reading a single disclosure.
The California Special Case
California caps the check at $300 and the fee at 15%, so the fee is $45. The twist is that you receive $255 net and repay the full $300, because the fee comes off the top of the face amount. On the money you actually received, $45 for 14 days is about 459% APR, noticeably higher than the regime’s headline suggests. Every per-$100 state prices on the face of the check, but California’s small cap makes the gap between the face amount and the net cash the widest, which is why the state gets its own line in any honest cost table.
What $300 Costs by Fee Regime
| Fee regime | Fee on $300 | Total due | APR on 14 days |
|---|---|---|---|
| 15% per $100 states | $45 | $345 | about 391% |
| 17.5% (Alabama) | $52.50 | $352.50 | about 456% |
| 36% APR capped states | about $9 for a month | about $309 after a month | 36% |
| California, net $255 | $45 | $300 on the check | about 459% on the $255 received |
The last two rows are different products wearing the same amount. In a 36% state the $300 is amortizing credit priced by the year; the California advance is a flat fee on a check you never fully receive.
The Cheaper Routes for $300
App advances. EarnIn, Dave, Brigit, MoneyLion, Chime, and Varo advance $20 to $700 against an incoming paycheck with no hard credit pull, and the cost is a tip or a subscription, about $5 to $25 in total. The catch is access: first-time users often see limits well under $300 until they have a history of direct deposits, so the app that advertises hundreds may advance you $80 today.
Credit union Payday Alternative Loans. Federal credit unions can make PALs of $200 to $2,000 at a 28% APR cap over 1 to 12 months. On $300, total interest lands around $9 to $25 over a short-to-medium term. You need membership first, which usually requires an employer, community, or regional tie, but the interest is a rounding error next to $45.
State-capped installment credit. In 36% cap states, $300 borrowed for a month costs about $9 in interest. Availability depends on the state and on each lender’s minimums, so it is worth a phone call.
When the Tribal Route Is the Only Shaped Option
In the 13 states that do not license payday lending, the storefront shelf is empty, and for declined profiles it can be empty everywhere. Tribal installment loans, chartered by federally recognized tribes, keep serving that demand because state rate caps generally do not apply to them. The cost reality is steep: at the market’s 400% to 800% APR, a $300 balance retired over two to three months carries roughly $150 to $300 in finance charges, and longer schedules cost more. Federal law still applies, so you are owed Truth in Lending disclosures before you sign and you can file a CFPB complaint afterward, and covered servicemembers are capped at 36% APR under the Military Lending Act. If a PAL or an app advance is reachable, it beats the tribal line on price every time, so take the tribal route only with the smallest amount and the shortest schedule that solves the problem.
Price the Fee, Not the APR Headline
The working rule for a $300 advance is to ask two questions of every offer: what is the total of payments, and what date is each due. Then compare that total across every product you can actually get. A 391% APR on a $45 fee and a 36% APR on a $9 month are the same idea in different units, and the product that wins is the one whose total you can retire on time. Our rates and fees page lists fee regimes state by state, the $300 loan page breaks down this amount specifically, and our calculators turn any offer into a payment schedule you can check against your paycheck.
