Amortization calculator

Estimate remaining balance, principal paid, and interest paid after a selected number of years on a fixed-rate loan.

What this calculator covers

Estimate how a fixed-rate loan balance declines over time after a selected number of years.

The walkthrough keeps the monthly payment, remaining balance, and principal-versus-interest progress visible in the same view.

Frequently asked questions

What does an amortization snapshot actually tell me?
It shows how much of the original loan balance has been paid down after a chosen number of years, along with how much of your payments went to principal versus interest during that stretch.
Why is so much of the early payment interest?
Each payment's interest portion is recalculated on the current balance. Early on the balance is large, so interest claims a bigger slice; as the balance falls, more of each fixed payment shifts toward principal.
Is the remaining balance the same as a lender's payoff quote?
No. This is a schedule estimate based on fixed-rate amortization math. A lender's payoff quote accounts for your exact payment history, any rounding adjustments, and the precise payoff date.
Does this calculator handle extra payments or variable rates?
No. The model assumes a fixed rate, equal monthly payments, and no extra principal payments. Use a dedicated extra-payment calculator for those scenarios.

Primary result

$350,014.66

A $375,000.00 fixed-rate loan at 6.25% over 30 years leaves about $350,014.66 after 5 years, with $24,985.34 of principal repaid.

Step-by-step solution

  1. 1.Use the fixed-rate amortization formula to estimate a monthly payment of $2,308.94.
  2. 2.Advance the schedule 5 years to estimate a remaining balance of $350,014.66.
  3. 3.Compare the original balance with the remaining balance to see $24,985.34 of principal repaid and $113,551.03 of interest paid to date.

Walkthrough

Visual walkthrough

Amortization tracks how a fixed monthly payment gradually shifts from mostly interest toward more principal over time.

  1. 01

    Set the fixed monthly payment

    The rate, loan amount, and term produce one fixed payment for a fully amortizing loan.

    $2,308.94 per month

  2. 02

    Move the schedule forward

    5 years = 60 payments

    The selected elapsed time determines how many payments have reduced the balance so far.

    $350,014.66 remaining

  3. 03

    Separate principal and interest paid to date

    The remaining balance lets you infer how much of the original loan has been repaid and how much total interest has been paid along the way.
