This real estate exam mortgage calculator helps you determine monthly mortgage payments based on loan amount, interest rate, and loan term. It's an essential tool for real estate professionals preparing for licensing exams.
How to Use This Calculator
To calculate your mortgage payment:
- Enter the loan amount in dollars
- Input the annual interest rate (APR)
- Select the loan term in years
- Click "Calculate" to see your monthly payment
The calculator will display your monthly payment, total interest paid over the loan term, and a breakdown of your payments over time.
Mortgage Payment Formula
The standard mortgage payment formula is:
M = P [i(1 + i)n] / [(1 + i)n - 1]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (APR/12/100)
- n = Number of payments (loan term in years × 12)
This formula accounts for the interest on the unpaid balance of your loan each month, which is why mortgage payments increase over time.
Example Calculation
Let's calculate a mortgage payment for a $200,000 loan at 4.5% APR over 30 years:
- Principal (P) = $200,000
- Annual interest rate = 4.5%
- Monthly interest rate (i) = 4.5%/12/100 = 0.00375
- Number of payments (n) = 30 × 12 = 360
Plugging these into the formula:
M = 200,000 [0.00375(1 + 0.00375)360] / [(1 + 0.00375)360 - 1]
M = $1,073.64 per month
Over 30 years, you would pay $386,470 in total, with $186,470 going to interest.
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 compounding interest, making it slightly higher for the same loan.
How does a mortgage interest rate affect payments?
A higher interest rate increases your monthly payments and total interest paid over the life of the loan. Conversely, a lower rate reduces these amounts.
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.
How do points affect mortgage payments?
Points are prepaid interest payments that lower your interest rate. Each point equals 1% of the loan amount and typically reduces your rate by 0.25%.
