What is a Mortgage Calculator?
A mortgage calculator is an online tool that estimates your monthly mortgage payments based on three key inputs:
- Loan Amount (Principal) – The total amount you plan to borrow.
- Interest Rate – The annual rate charged by your lender.
- Loan Term – The length of time over which you will repay the loan, usually in years.
By using these values, the calculator applies a standard amortization formula to provide both monthly payments and the total payment over the life of the loan. This helps you understand your financial obligations before committing to a mortgage.
How the DCU Mortgage Calculator Works
The calculator uses the standard mortgage formula:M=1−(1+r)−nP×r
Where:
- M = Monthly payment
- P = Loan principal (amount borrowed)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of monthly payments (loan term × 12)
This formula calculates the fixed monthly payment required to pay off the mortgage fully over the chosen term.
How to Use the DCU Mortgage Calculator
Using the DCU Mortgage Calculator is easy and straightforward. Follow these steps:
Step 1: Enter Your Loan Amount
Input the total amount you plan to borrow in dollars. For example:
- $200,000 for a home
- $350,000 for a larger property
Step 2: Enter the Interest Rate
Provide the annual interest rate (%) offered by your lender. Example rates:
- 3% (low rate)
- 5% (average)
- 6–7% (higher-rate mortgages)
Step 3: Enter the Loan Term
Specify the mortgage term in years. Common terms include:
- 15 years
- 20 years
- 30 years
Step 4: Click Calculate
The calculator instantly displays:
- Monthly Payment – Amount you will pay each month.
- Total Payment – Total cost over the loan’s lifetime, including principal and interest.
Step 5: Reset if Needed
Click the Reset button to start a new calculation with different values.
Example Calculation
Let’s say:
- Loan Amount: $250,000
- Interest Rate: 4%
- Term: 30 years
The calculation would work as follows:
- Convert annual rate to monthly: 4 ÷ 12 = 0.003333
- Total payments: 30 × 12 = 360 months
- Monthly Payment:
M=1−(1+0.003333)−360250,000×0.003333≈1,193.54
Total Payment: $1,193.54 × 360 = $429,674.40
This example shows how interest adds significantly to the total cost over time.

Understanding Monthly Payments
Monthly payments include a portion of the principal and a portion of interest. In early years, more of your payment goes toward interest. Over time, as the principal decreases, interest decreases and more goes toward the principal.
This structure is important for understanding equity growth and planning prepayments.
Example of Multiple Scenarios
| Loan Amount | Interest Rate | Term (Years) | Monthly Payment | Total Payment |
|---|---|---|---|---|
| $200,000 | 3.5% | 30 | $898.09 | $323,312.40 |
| $200,000 | 4% | 30 | $954.83 | $343,738.80 |
| $200,000 | 3.5% | 15 | $1,430.33 | $257,459.40 |
These comparisons highlight how interest rate and term significantly affect payments and total cost.
