Straight answer
A payday loan is a short-term, small-dollar loan — commonly $100 to $1,000 — repaid in a single payment, typically on your next payday. Instead of a traditional interest rate, most providers charge a flat fee per $100 borrowed. Because that fee is charged over such a short window, the equivalent APR can run into the triple digits even though the dollar cost of one loan may be modest. Whether it's a reasonable option depends on how confident you are that you can repay it in full on the due date.
How a payday loan actually works
You borrow a set amount, and in exchange, you agree to repay that amount plus a fee — usually as a single withdrawal from your bank account on or around your next payday. There's typically no monthly installment schedule; it's structured as one loan, one repayment. That simplicity is the appeal, and also the risk: if your next paycheck doesn't stretch to cover the full amount, you may be tempted to re-borrow immediately, which is where costs can compound quickly.
What a payday loan actually costs
Most providers price payday loans as a flat fee for every $100 (or similar unit) borrowed, rather than a percentage rate that accrues daily. The table below illustrates how that fee structure translates into an annualized rate for comparison — these are hypothetical examples, not rates offered by any specific lender in Crednio's network.
| Amount borrowed | Example flat fee | Repayment term | Total repaid | Approximate APR |
|---|---|---|---|---|
| $100 | $15 | 14 days | $115 | ~391% |
| $300 | $45 | 14 days | $345 | ~391% |
| $100 | $15 | 30 days | $115 | ~182% |
| $500 | $75 | 30 days | $575 | ~182% |
Illustrative only, based on a common $15-per-$100 fee example used industry-wide for comparison purposes. Actual fees, terms and APR are set by the individual lender and your state's rules, and can differ significantly from these figures. Always get the exact dollar fee and due date from the provider before accepting an offer.
Payday loan rules vary a lot by state
Some states permit payday lending within specific fee and loan-amount limits. Others allow it only through alternative structures, such as installment-style payday products with longer terms. A number of states restrict or effectively prohibit traditional payday lending altogether. That means the same request can look very different depending on where you live — both in what's available and what it costs. Visit our state guides for a general overview, and confirm current details with your state's financial regulator before applying.
Payday loan or installment loan?
A payday loan is built for a small, specific shortfall you're confident you can repay by your next paycheck. If you'd rather spread the cost over several smaller payments instead of one lump sum, an installment loan is usually the better fit — see our full payday vs. installment comparison for a side-by-side look.
Before you borrow, ask these questions
- What is the exact total dollar amount due, and on what date?
- What happens if I can't repay in full on that date — is an extended payment plan available, and what does it cost?
- Is this lender licensed to operate in my state?
- Does repayment happen automatically from my bank account, and what if there isn't enough there?
- Is there a lower-cost way to cover this same expense?
Alternatives worth considering first
- An installment loan, which spreads repayment over a longer, potentially more manageable schedule.
- A payment plan negotiated directly with the biller or creditor you're trying to cover.
- Local assistance programs or an employer paycheck-advance option, where available.
Our payday loan alternatives guide covers this in more depth.
If you decide to move forward
Confirm the provider is licensed in your state, read the complete loan agreement before signing — not just the summary — and borrow only the amount you're confident you can repay on the due date without needing to immediately re-borrow.
A quick checklist
Before you apply for a payday loan
- 01 Know the exact total repayment amount, not just the amount borrowed.
- 02 Confirm the due date and how repayment will be collected.
- 03 Ask what happens if you can't repay on time, before you need to know.
- 04 Check that the lender is licensed in your state.
- 05 Compare the total cost against an installment loan or other alternative.
- 06 Read the full agreement — not just the application summary.

FAQ
Payday loan questions, answered
What is a payday loan? +
A payday loan is a small, short-term loan designed to be repaid in one lump sum, usually on your next payday, typically within two to four weeks. It's meant to cover a temporary gap, not a long-term borrowing need.
Why is the APR on a payday loan often so high? +
Payday loans are usually priced as a flat fee for the amount borrowed rather than interest that accrues over time. When that flat fee is converted into an annualized rate for comparison purposes, the short repayment window makes the resulting APR look much higher than a longer-term loan, even though the dollar cost of a single loan may be modest.
Are payday loans legal in my state? +
It depends on the state. Some states permit payday lending within specific fee and amount limits, some allow it only under alternative loan structures, and others restrict or effectively prohibit it. Check our state guides for a general overview, and confirm current rules with your state's financial regulator.
What happens if I can't repay a payday loan on time? +
Policies vary by lender and state. Some providers offer an extended payment plan, others may charge an additional fee or attempt to collect via your bank account, which can trigger insufficient-funds charges. Ask about this before you borrow, not after you're behind.
Is a payday loan or an installment loan better for me? +
A payday loan can make sense for a small shortfall you're confident you can repay by your next paycheck. An installment loan spreads repayment over a longer schedule, which can be easier to manage if you'd rather pay smaller amounts over time. Compare both before choosing.
