To use the Alaska USA Federal Credit Union mortgage calculator:

  1. Enter the loan amount you're considering (e.g., $200,000)
  2. Input the interest rate offered by Alaska USA Federal Credit Union (e.g., 4.5%)

Mortgage Payment Formula

The calculator uses the standard mortgage payment formula:

M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]

Where:

  • M = Monthly payment
  • P = Principal loan amount
  • i = Monthly interest rate (annual rate divided by 12)
  • n = Number of payments (loan term in years multiplied by 12)

This formula calculates the fixed monthly payment required to pay off a loan with compound interest.

Worked Example

Let's calculate a mortgage payment for a $200,000 loan at 4.5% interest over 30 years:

  1. Convert annual interest rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
  2. Calculate number of payments: 30 years × 12 = 360 payments
  3. Plug values into the formula:
    M = $200,000 [ 0.00375(1 + 0.00375)360 ] / [ (1 + 0.00375)360 - 1 ]
  4. The calculation results in approximately $1,073.64 per month

This example shows that a $200,000 loan at 4.5% over 30 years would have a monthly payment of about $1,073.64.

Frequently Asked Questions

What is the difference between APR and APY?

APR (Annual Percentage Rate) is the simple annual interest rate, while APY (Annual Percentage Yield) includes the effect of compounding interest. APY is generally higher than APR for the same loan.

How does a mortgage interest rate affect my payment?

A higher interest rate means higher monthly payments and more total interest paid over the life of the loan. A lower rate reduces both monthly payments and total interest costs.

What is PMI and when is it required?

PMI (Private Mortgage Insurance) is required when you put down less than 20% on a conventional loan. It protects the lender if you default. PMI is usually temporary and can be canceled once your equity reaches 20%.
