Plan borrowing with monthly payment and payoff insights. Test extra payments and compare repayment outcomes. Download schedules for budgeting, decisions, reviews, tracking, and planning.
Enter the loan principal, annual interest rate, and term in years. Choose how often you will make payments. Add optional fees if they are financed into the loan balance.
Enter any recurring insurance amount paid with each installment. Add an extra payment if you want to reduce principal faster. Pick a start date to estimate payment dates and the final payoff date.
Press the button to generate the payment summary, savings analysis, plot, and full amortization table. Use the CSV or PDF buttons to save the schedule for review, budgeting, or lender comparison.
The calculator first creates the financed amount:
Financed Amount = Principal + Financed Fees
Then it calculates the periodic interest rate:
Periodic Rate = Annual Rate / Payments Per Year
For standard amortization, the base payment is:
Payment = P × r / (1 − (1 + r)^−n)
Where P is financed amount, r is periodic rate, and n is total number of payments.
Each period is split into interest and principal:
Interest = Current Balance × Periodic Rate
Principal Paid = Scheduled Payment − Interest
New balance becomes:
New Balance = Old Balance − Principal Paid
Extra payment increases principal reduction, shortens the term, and lowers total interest. Insurance is tracked separately because it affects cash outflow but not the loan balance.

A personal loan amortization calculator helps borrowers understand how each payment changes the debt over time. The schedule shows exactly how much of each installment goes to interest and how much reduces the remaining principal. This view is useful when planning budgets, comparing lenders, and deciding whether a shorter term or lower monthly payment fits your goals better.
At the beginning of most loans, a larger part of each payment covers interest. As the balance drops, the interest portion becomes smaller and more of each payment goes toward principal. This shift is why many borrowers study amortization tables before signing a contract. The table explains total borrowing cost and makes repayment progress easier to track.
One of the most useful features in an advanced loan tool is extra payment testing. Even a modest additional amount paid every month can reduce the total interest significantly and shorten the payoff timeline. This calculator compares the standard path with an accelerated path so you can measure periods saved and interest saved in one place.
Export options support practical use beyond simple calculation. A CSV file works well for spreadsheet review, while a PDF file helps with reporting, discussions, and record keeping. Combined with the graph and schedule table, these features turn a basic calculator into a decision support tool for personal finance planning.
It shows each payment date, payment amount, interest charge, principal reduction, and remaining balance. It also summarizes payoff timing, total interest, and total cash outflow over the life of the loan.
Interest is calculated on the current outstanding balance. Since the balance is highest at the beginning, the interest portion is also highest early in the repayment schedule.
Yes. Extra payments usually reduce principal faster, which lowers future interest charges and often shortens the number of periods needed to fully repay the loan.
This version can add financed fees to the opening balance. That means the payment and total interest are calculated on principal plus financed fees, not principal alone.
Insurance may increase each installment but usually does not reduce the loan balance. Tracking it separately gives a clearer picture of true repayment cost and balance movement.
Yes. The calculator supports several payment frequencies. Changing payment frequency affects the periodic rate, the number of installments, and the expected payoff timeline.
No. When the remaining balance becomes smaller than a normal installment, the last loan payment is adjusted so the balance reaches zero without overpaying principal.
Compare total interest, total paid, payment affordability, and payoff speed. Reviewing the full amortization schedule often reveals cost differences that simple headline rates do not show.
