Payday Loan Cost Calculator: The Real APR and Total Fees
A payday lender quotes a fee, not a rate. Enter the fee and the term and this converts it into the APR you'd be shown anywhere else — then counts what every rollover adds, and prices the same borrowing as an ordinary installment loan.
Your payday loan
The amount, the fee the lender quotes per $100, and how many times you expect to renew it rather than repay the principal.
What each renewal costs
At $75.00 a term, the fees alone reach $500 — the whole amount you borrowed — after 7 terms.
| Term | Due on day | You pay | Fees to date | Still owed |
|---|---|---|---|---|
| 1 | 14 | $75.00 | $75.00 | $500 |
| 2 | 28 | $75.00 | $150.00 | $500 |
| 3 | 42 | $75.00 | $225.00 | $500 |
| 4 | 56 | $575.00fee + principal | $300.00 | $0 |
Cost of borrowing $500
Fees and interest only — the principal is excluded from both bars, because you repay that either way.
The two windows differ on purpose. The personal loan's interest buys you its full term and retires the principal along the way; the payday fees buy you 8 weeks and leave the principal exactly where it started.
Where the APR comes from
There is only one formula, and it has no compounding in it. The fee is charged once, up front, on a principal that doesn't amortize. To express it as an annual rate you ask what fraction of the loan the fee represents, then how many of those terms fit in a year:
APR = (fee ÷ amount) × (365 ÷ term in days) × 100
A $15 fee per $100 over fourteen days: 0.15 × 26.07 × 100 = 391%. A $20 fee per $100 over thirty days: 243%. Notice what's absent. The amount borrowed doesn't appear, because the fee scales with it — $100 and $1,000 carry the identical rate. And the number of rollovers doesn't appear either. Renewing the loan never changes its APR. Every term is priced the same. What renewal changes is how many terms you buy.
Lenders object, reasonably, that nobody borrows for a year, so an annual rate overstates what you actually hand over. True. That is why the calculator shows both: the annualized rate, which lets you set this loan next to a credit card, and the total fees in dollars, which is what leaves your account. The loan is expensive on either scale.
The rollover is the product
A payday loan is due in full — principal and fee together — on a single date, typically your next payday. That is a hard ask for someone who needed the money badly enough to pay 391% for it, and the loan has an escape hatch for exactly that moment: pay the fee alone, and the due date moves.
Nothing was repaid. The principal is where it started, the next term costs the same fee, and the ledger in the calculator above shows the balance column refusing to move while the fees column climbs. At $15 per $100, cumulative fees equal the entire amount borrowed after seven terms — a little over three months — and the principal is still outstanding. The debt has, at that point, cost exactly as much as it was worth, and bought nothing.
This is the same shape as the credit card minimum payment trap, compressed from decades into weeks. In both cases a payment sized to feel affordable is calibrated so that principal barely moves, and the lender's revenue is the length of time you stay.
Alternatives to a payday loan
Roughly in order of what they cost. The first is free and gets skipped most often.
Ask the biller for time
A payday loan is almost always taken out to pay something else — a utility, a car repair, a hospital bill, rent. Most of those creditors will split a bill across pay periods at no charge, and none of them charge 391% to wait. Ask before you borrow, not after. In the U.S., dialing 211 reaches local assistance programs for utility and rent shortfalls specifically.
A credit union Payday Alternative Loan
Federal credit unions offer small short-term loans built as a direct substitute for this product. Federal rules cap the interest rate at 28% and the application fee at $20. Put those terms into the comparison above against a $15-per-$100 fee and the gap is not close. You generally have to be a member, which is worth arranging before the month you need the money.
A small installment loan
An ordinary personal loan repays principal on every payment, so it ends. That is the structural difference, and it matters more than the rate: the personal loan payoff calculator will give you a date, which is a sentence a payday loan cannot produce. Watch the origination fee, and check that there is no prepayment penalty.
A paycheck advance from your employer
Some employers advance earned wages directly, and some contract with apps that do it. The former is usually free. With the latter, read what the expedite fee and the suggested "tip" come to as a percentage of a small advance held for a few days — run it through the fee field above, since that is what it is.
A credit card cash advance — last, not never
Cash advances carry a fee, a higher-than-purchase APR, and no grace period: interest starts the day you take the money. They are genuinely expensive, and they are still priced in the twenties or thirties rather than the hundreds. How credit card interest works covers what that actually accrues to.
If you already have one
Stop the renewals before you optimize anything else. Every rollover is another full-price term, and no payoff strategy outruns a fee that reprices every two weeks. Many states require lenders to offer an extended payment plan that splits the balance across several pay periods without an additional fee — request it in writing, before the due date, because after the due date it is usually off the table. Some states also give you one business day to cancel a loan outright.
If the cash isn't there, borrowing once from a credit union to retire the payday balance converts a 391% debt into a two-figure APR and stops the fee clock. That is refinancing in the plain sense: the amount owed doesn't fall, but it stops growing at a rate nothing can service. From there it becomes an ordinary debt, and how to pay off debt fast applies — as does the argument for putting the highest APR first, which is exactly what the avalanche method says about a balance like this one.
Frequently asked questions
What is the true cost of a payday loan?
The fee, multiplied by however many terms you end up borrowing for. A $15 fee per $100 on a $500 loan is $75 due in two weeks. Repay on the first due date and $75 is the whole cost. Roll it over three times — pay the fee, keep the cash — and you have paid $300 to borrow $500, still owe the $500, and are eight weeks in. The fee is quoted per term, not per loan, which is why the honest answer to "what does it cost" depends entirely on how long you carry it.
What is the APR on a payday loan?
Annualize the fee over the term: APR = (fee ÷ amount) × (365 ÷ term in days) × 100. A $15 fee per $100 borrowed for 14 days works out to 391%. A $20 fee per $100 for 30 days is 243%. The APR does not change with the amount borrowed, because the fee scales with it — a $100 loan and a $1,000 loan at the same fee schedule carry the same rate.
Why is the APR so high if the fee is only $15?
Because $15 is a lot of money for two weeks. APR exists to make prices comparable across terms, and it does that by asking what the same rate of charge would come to over a year. Fifteen dollars on a hundred, twenty-six times a year, is $391. Lenders will tell you the APR is misleading because nobody borrows for a year. That is a fair objection to the framing and a poor defense of the price — the calculator above shows both numbers, the annualized rate and the actual dollars, precisely so you can judge the loan on either.
What happens when you roll over a payday loan?
You pay the fee, the lender extends the due date, and the principal stays exactly where it was. Nothing has been repaid. The next term costs the same fee as the first, and the one after that, and the arithmetic doesn't bend: at $15 per $100, the fees alone equal the entire amount you borrowed after seven terms — a little over three months — and you still owe the principal on top.
Is a payday loan cheaper than an overdraft or a late fee?
Sometimes, for a single term, and that is the case payday lenders make. A flat fee charged for a very short shortfall can annualize to a rate above a payday loan's. But the comparison holds only if you repay on the first due date, and it compares two expensive options rather than identifying a cheap one. Before choosing between them, ask the biller for more time — most utilities, hospitals, and landlords will arrange a payment plan for free.
What are the alternatives to a payday loan?
In rough order of cost: a payment plan directly with whoever you owe, which is usually free; a Payday Alternative Loan from a federal credit union, where federal rules cap the interest rate at 28% and the application fee at $20; a small personal or installment loan; an advance from your employer; and, as a last resort, a credit card cash advance, which is expensive but priced in the twenties or thirties rather than the hundreds. Local assistance programs, reachable by dialing 211 in the U.S., cover utility and rent shortfalls that no loan should be funding.
How do I get out of a payday loan I already have?
Stop the rollover first, because every renewal buys time at full price. Many states require lenders to offer an extended payment plan that splits the balance across several pay periods at no extra fee — ask for it in writing before the due date. Some states also give you a right to cancel a new loan within one business day. If the cash simply isn't there, a small installment loan from a credit union to retire the payday balance converts a 391% debt into a two-figure APR, and the payday lender's fee clock stops.
Does a payday loan affect your credit score?
Usually only in one direction. Most payday lenders don't report to the three major credit bureaus, so paying on time builds nothing. Default, though, tends to end with the debt sold to a collection agency, and collection accounts do get reported. A payday loan is therefore a credit product that can hurt your file and can't help it.

Estimates are educational only and are not financial advice. The APR is the loan's fee annualized over a 365-day year with no compounding, the convention used for single-payment loans; fees are assumed flat per term and identical on every rollover, and no late charges, returned- payment fees, or verification fees are modeled. Payday lending rules, fee caps, rollover limits, extended payment plans, and rescission rights vary by state, and some states prohibit the product outright. The personal loan comparison amortizes the same principal at the APR and term you enter, with interest compounded monthly.
