An amortization schedule shows how each payment is split between interest and principal over time. Early payments often go more heavily toward interest, while later payments reduce more principal.

What amortization helps you understand

  • How much interest you may pay over the life of a loan.
  • How principal balance falls over time.
  • How extra payments may shorten payoff time.
  • Why a longer term can increase total cost.

Use this before borrowing

Even without a full schedule, you can compare monthly payment and total repayment with a simple calculator. If the estimated payment is already tight, the final loan may be too risky.
