Amortization Calculator

An amortization calculator is a financial tool that shows how a loan is paid off over time through regular payments.
It breaks each payment into:
Principal (the amount you borrowed)
Interest (the cost of borrowing)
It also shows:
Total interest paid
Remaining balance after each payment
A full amortization schedule (payment-by-payment breakdown)

It helps you understand the true cost of a loan and how your payments behave over time.
Key benefits:
Transparency: See exactly where your money goes
Planning: Understand long-term financial commitments
Comparison: Evaluate different loan offers (rates, terms)
Savings strategy: See how extra payments reduce interest and loan duration
👉 Example insight: Early in a loan, most of your payment goes toward interest—not principal.

It uses a standard loan formula based on:
Loan amount
Interest rate
Loan term (length)
Payment frequency (monthly, etc.)
At its core, it calculates your fixed payment and then applies this logic for each period:
Compute interest for the current balance
Subtract that from your payment → gives principal paid
Reduce the remaining balance
Repeat for each period until the loan is paid off
