The calculator will display your monthly payment and provide a breakdown of how your payment is allocated between principal and interest.
Formula Used
The monthly mortgage payment is calculated using the standard mortgage formula:
Mortgage Payment Formula
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount (Home Price - Down Payment)
- i = Monthly interest rate (Annual Rate / 12)
- n = Number of payments (Loan Term in years × 12)
This formula accounts for the interest on the loan and amortizes the principal over the life of the loan.
Worked Example
Let's calculate the monthly payment for a $300,000 home with a $60,000 down payment, 6% interest rate, and a 15-year term.
- Principal (P) = $300,000 - $60,000 = $240,000
- Monthly interest rate (i) = 6% / 12 = 0.5% or 0.005
- Number of payments (n) = 15 × 12 = 180
- Plugging into the formula: M = $240,000 [ 0.005(1 + 0.005)^180 ] / [ (1 + 0.005)^180 - 1 ]
- Calculating: M ≈ $1,850.75
So, the monthly payment would be approximately $1,850.75.
Frequently Asked Questions
- How does a 15-year mortgage compare to a 30-year mortgage?
- A 15-year mortgage typically has a lower monthly payment but higher interest costs over the life of the loan. The choice depends on your financial situation and goals.
- Can I pay extra toward my mortgage to pay it off faster?
- Yes, making extra payments can help you pay off your mortgage faster and save on interest. This calculator can help you determine how much extra you need to pay each month to reach your goal.
- What happens if interest rates rise after I get my mortgage?
- If interest rates rise, your monthly payment may increase if you have an adjustable-rate mortgage (ARM). With a fixed-rate mortgage, your payment remains the same, but you'll pay more interest over time.
- Are there any fees associated with a 15-year mortgage?
- Yes, there may be origination fees, appraisal fees, and closing costs associated with getting a mortgage. These fees can vary depending on the lender and your location.
- Can I refinance my mortgage to a 15-year term?
- Yes, you can refinance your existing mortgage to a 15-year term if you qualify and meet the lender's requirements. Refinancing can help you save on interest and pay off your mortgage faster.
