Payday Loan Calculator
Choose your state's fee rule, enter the amount and the days to your pay date. The calculator returns the fee, the total due, the calendar due date, the APR, and what rolling the loan over would add.
Reading the Result
The fee for one term is what the loan costs if you repay on the due date. The total is the check or debit the lender takes that day. The APR is the annualized rate the lender must print in the agreement. The rollover line is the one to stare at: it shows what happens when the due date arrives and the money is not there. Each extension charges the whole fee again while the principal stays put.
A $300 loan at $15 per $100, rolled twice, costs $135 in fees over six weeks. The same $300 on a 36% installment plan over three months costs about $18 in interest. That gap is the whole argument for checking whether your state offers the cheaper product before you take the faster one.

Frequently Asked Questions
How do I find my state's fee cap for the calculator?
Pick it from the list or open your state page, which lists the maximum fee per $100 with the statute. Common caps are $15 per $100, $10 plus a $5 fee in Florida, and 36% APR in the capped states, which is about $1.38 per $100 for two weeks.
What does a rollover cost?
A rollover charges the full fee again for another term without reducing the principal. Two rollovers on a $15 per $100 loan of $300 means $135 in fees for six weeks and you still owe the $300. Several states ban rollovers or require a free extended payment plan instead.
Is the due date always my next payday?
Usually. Most payday loans are due on the next pay date after the loan, which gives 7 to 31 days depending on how you are paid. The calculator uses the days you enter and shows the calendar date so you can check it against your pay schedule.
Why does the APR change when I change the days?
Because APR annualizes the fee over the actual term. The same $45 fee is 391% APR over 14 days but 196% over 28 days. That is why a longer term at the same flat fee is cheaper per day, and why lenders in most states charge the same fee for 8 days as for 14.
Can the calculator tell me if a payday loan is legal in my state?
Not by itself. The state list on this page shows the states with a 36% cap, where a payday lender cannot operate on a two-week fee. For the full answer, including prohibited states, open the state page from the state hub.
