What is a Loan Amortization Calculator?
A Loan Amortization Calculator is a financial planning tool that generates an amortization schedule for any loan. An amortization schedule is a table that shows:
- Monthly payment amount
- Interest paid each month
- Principal repayment each month
- Remaining loan balance after each payment
It helps borrowers clearly visualize how their loan reduces over time.
How Loan Amortization Works
Loan amortization works on a simple principle: every monthly payment is split into two parts:
- Interest Payment – The cost of borrowing money
- Principal Payment – The amount that reduces the loan balance
In the early years of a loan, a larger portion goes toward interest. Over time, the principal portion increases while interest decreases.
Basic Formula Used
The standard loan payment formula is:
Monthly Payment = P × r × (1 + r)^n / [(1 + r)^n – 1]
Where:
- P = Loan amount (principal)
- r = Monthly interest rate
- n = Total number of payments
