Loan Payment Schedule Generator

A loan payment schedule generator (also known as an amortization calculator) is a financial tool that creates a complete payment-by-payment breakdown for any amortizing loan. For each payment period, it calculates the exact split between principal and interest, the remaining balance after the payment, and the cumulative interest paid to date. The schedule covers the entire loan term from the first payment through the final payoff. Our loan payment schedule generator runs entirely in your browser with no data uploaded to any server and supports multiple payment frequencies including weekly, bi-weekly, monthly, and accelerated bi-weekly schedules.

1. Enter Your Loan Parameters: Input the principal loan amount, annual interest rate (APR), loan term in years or months, and choose a payment frequency (weekly, bi-weekly, monthly, or accelerated bi-weekly). Optionally enter an extra payment amount to apply to each regular payment.
2. Configure Extra Payment Scenarios: Optionally set a recurring extra payment amount that will be applied to the principal with each payment. The loan payment schedule generator calculates how this extra amount reduces the loan term and total interest, and generates a side-by-side comparison with the standard schedule.
3. Review & Export Your Amortization Schedule: The calculator displays a complete payment-by-payment schedule showing payment number, date, principal, interest, total payment, remaining balance, and cumulative interest. Compare standard vs accelerated payoff scenarios and download the full schedule as a CSV file for offline analysis in Excel or Google Sheets.

• Payment Breakdown: Each row in the amortization schedule shows the exact split between principal and interest for that payment. Early payments are mostly interest, while later payments are mostly principal - this is the standard amortization curve for any fixed-rate loan.
• Remaining Balance: The outstanding loan balance after each payment is displayed, showing how the principal decreases over time. This helps you track your equity buildup and know exactly where you stand in the loan lifecycle.
• Cumulative Interest: The running total of all interest paid to date is shown alongside each payment. This running total makes it easy to see the real cost of borrowing and how extra payments reduce the total interest burden.
• Scenario Comparison: When extra payments are included, the generator shows both the standard schedule and the accelerated schedule side by side, with the total interest savings, months saved off the term, and the new payoff date clearly highlighted.

The loan payment schedule generator is 100% free with no signup required. All calculations are performed locally in your browser - your loan amounts, interest rates, and payment details never leave your device. There are no file size limits or usage caps. The tool supports all standard payment frequencies and extra payment scenarios, and includes the ability to download the complete amortization schedule as a CSV file for offline analysis. Use it as many times as you need to plan mortgage payments, compare auto loan offers, analyze business financing, or model any loan repayment scenario.
