Cash Advance App Cost Calculator

Cash advance apps often charge a monthly fee or a suggested tip instead of interest, which can make the cost hard to see. This calculator converts that monthly fee into total fees, a total repaid, and an effective APR.

How this calculator works

Many cash advance apps price their product as a subscription or a tip rather than as interest. The calculator takes the advance amount and the monthly fee as a percentage of it, then multiplies by the months you take to repay.

Because the fee repeats every month, the total cost climbs with the repayment period. The effective APR annualises those fees so you can compare the app against a payday loan or an installment loan on the same footing. Annualised, the cost can rival a payday loan.

Enter the monthly fee your app actually charges. Some apps adjust the fee by plan tier or by how much you advance, so use the number that applies to you.

Frequently asked questions

Why annualise a monthly fee?
A monthly fee looks small next to a one-time payday fee, but it repeats every month you hold the advance. The effective APR puts that repeating cost on the same yearly scale as other credit so the comparison is honest.
Is the monthly fee the same as interest?
Functionally it is a cost of borrowing, even when the app calls it a subscription or a tip. The calculator treats it as the price of the advance and expresses it as both a total and an annual rate.
How do I find the monthly fee percentage?
Divide the monthly fee by the advance amount and multiply by 100. If an app charges a flat fee, you can enter the equivalent percentage, or just note the total fees the calculator reports.
Does a longer repayment period cost more?
Yes. The monthly fee is charged for each month the advance is outstanding, so more months means more fees and a higher total repaid. Repaying faster lowers the total cost.
