Mortgage Payment Details
What is a Fixed Mortgage?
A fixed-rate mortgage is a type of home loan where the interest rate remains the same throughout the term of the loan. This ensures predictable monthly payments, making budgeting easier. Unlike adjustable-rate mortgages (ARMs), fixed mortgages offer stability, which is ideal for homeowners who prefer long-term financial certainty.
How the Fixed Mortgage Calculator Works
The calculator uses the standard mortgage formula:M=P(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Loan principal (amount borrowed)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (years × 12)
This formula accounts for compound interest, meaning each month’s interest is calculated on the remaining loan balance.
If the interest rate is 0%, the formula simplifies to dividing the loan amount by the total months.

Using this calculator is simple, even for beginners:

Step 3: Enter the Interest Rate
Input the annual fixed interest rate as a percentage.
Example: 4.5%
Step 4: Click “Calculate”
The calculator instantly displays:
- Monthly Payment – The amount you pay each month

Example Calculation
Suppose you plan to buy a home with the following details:
- Loan Amount: $300,000
- Interest Rate: 5%
- Loan Term: 30 years
Calculation:
- Monthly interest rate: 5 ÷ 100 ÷ 12 = 0.004167
- Total months: 30 × 12 = 360
- Monthly payment:
M=300,000∗0.004167/(1−(1+0.004167)−360)≈$1,610.46
- Total payment: 1,610.46 × 360 ≈ $579,765.60
This means you will pay $1,610 per month for 30 years, totaling $579,765, including interest.
