Estimate the total cost of a payday loan, including fees, interest, and repayment amount.

Total Repayment

APR (Annual Percentage Rate) shows the true yearly cost of borrowing. Payday loan APRs are typically much higher than credit cards (~24%) or personal loans.

What This Calculator Does

This payday loan calculator estimates the total cost of a short-term loan, including the principal amount, interest charges, and any applicable fees. It provides a clear breakdown of what you will owe by the repayment date, helping you understand the true cost before committing to a loan.

How the Calculation Works

The calculator uses the loan amount, the annual percentage rate (APR), the loan term in days, and any fixed fees to compute the total repayment amount. The core logic follows standard payday lending practices:

This method assumes a simple daily interest accrual, which is standard for most payday lenders. The APR reflects the annualized cost of borrowing, including interest and fees, expressed as a percentage.

How to Use the Calculator

  1. Enter the loan amount – the principal you plan to borrow.
  2. Enter the APR – the annual percentage rate offered by the lender.
  3. Enter the loan term – the number of days until repayment is due.
  4. Enter any fixed fees – if the lender charges a flat fee (e.g., a $15 processing fee), include it here.
  5. Click calculate – the tool will display the total interest, total fees, and the full repayment amount.

Example Calculation

Suppose you borrow $300 with an APR of 400% for a term of 14 days, and the lender charges a $20 processing fee.

In this example, you would owe $366.03 at the end of the 14-day term. The effective cost of borrowing is significantly higher than the principal due to the high APR and fees.

Understanding Your Results

The output shows three key figures:

Payday loans typically carry very high APRs, often exceeding 300% or 400%. Even a small loan can result in substantial interest charges over a short period. Use this breakdown to compare loan offers and assess affordability.

Frequently Asked Questions

What is a typical APR for a payday loan?

APRs for payday loans often range from 300% to 600% or higher, depending on the lender and local regulations. Some states cap APRs at lower levels, so check your local laws.

Can I use this calculator for installment loans?

This calculator is designed for single-payment payday loans with a fixed term in days. For installment loans with multiple payments, a different calculator that accounts for amortization would be more appropriate.

What happens if I cannot repay on time?

If you miss the repayment date, the lender may charge late fees, roll over the loan (adding new fees and interest), or report the default to credit bureaus. This calculator does not estimate those additional costs.

Does the calculator include origination fees?

Yes, if you enter a fixed fee amount, it is added to the total cost. Origination, processing, or administrative fees are common in payday lending.

Why is the interest so high for a short-term loan?

Payday loans are designed for short-term, high-risk borrowing. The high APR reflects the lender's risk and the short repayment window. Even a small loan can accrue significant interest when the APR is high.
