Payday Loan Calculator: Fees, Payoff, and True APR
Price any fee-based offer before it prices you: the tool turns an amount, a fee, and a term into the payoff you would owe and the annual rate the fee really represents.
This calculator prices any offer built on a flat fee: enter the amount, the fee, and the term, and it returns the payoff due on the due date plus the annualized rate the fee represents. The defaults describe the most common online offer in this market, $300 at $15 per $100 for 14 days. That is a $45 fee on a $345 payoff, an annual rate of about 391%. Change any input and every figure recomputes instantly.
Two numbers come out of every run, and they answer different questions. The payoff is what must be in your account on the due date; plan for it now, not on the morning it clears. The APR is the price of the time you are buying, and it is the only figure that compares fairly against alternatives such as a credit union PAL capped at 28% APR or a licensed Virginia or Illinois installment loan at the 36% cap.
The regional reality is worth restating. Three of the six jurisdictions this site covers, Maryland, Pennsylvania, and Washington DC, license no storefront product at these terms, so most offers at this pricing arrive from unlicensed online lenders or tribal lenders working under sovereign charters, where schedules can run 400% to 800% APR over months rather than weeks. Residents of Virginia and Illinois should price the licensed 36% market first, because the gap between 36% and 391% is the entire argument for checking. Delaware licenses advances up to $1,000 with no fee cap, so two contracts at the same amount can carry very different prices; run both through the calculator before signing either.
The defaults show the market's common case: $300 borrowed at $15 per $100 for 14 days, a $45 fee on a $345 payoff. Each state's rulebook is summarized on our rates and fees page.
When the math on an offer worries you, compare the licensed routes on our rates and fees page, or start a no-fee request through the application page and see what comes back in writing.
