Understanding Mortgage Payments
Mortgage payments consist of two major components:
Principal
The principal is the original amount borrowed.
For example:
- Loan Amount = $400,000
As payments are made, the principal balance decreases.
Interest
Interest is the fee charged by the lender for borrowing money.
For example:
- Mortgage = $400,000
- Interest Rate = 6%
The lender earns interest while you repay the loan.
Mortgage Payment Formula
The calculator uses the standard mortgage amortization formula:
M=P(1+r)n−1r(1+r)n
Where:
- M = Monthly mortgage payment
- P = Loan amount
- r = Monthly interest rate
- n = Total number of monthly payments
Additional calculations:
Monthly Interest Rate:
r=12Annual Interest Rate
Number of Payments:
n=Years×12
Total Payments:
Total Payments = Monthly Payment × Number of Payments
Total Interest:
Total Interest = Total Payments − Loan Amount
Example Calculation
Let's calculate a typical mortgage.

| Mortgage Amount | $400,000 |
| Interest Rate | 6% |
| Loan Term | 30 Years |
Results

|---|---|
| Monthly Payment | $2,398 |
| Total Payments | $863,280 |
| Total Interest | $463,280 |
Values are approximate and may vary slightly due to rounding.
This example shows how interest can significantly increase the total cost of borrowing over time.

15-Year vs. 30-Year Mortgage
One of the biggest decisions homebuyers face is choosing a loan term.
15-Year Mortgage
Advantages:
- Lower interest costs
- Faster equity building
- Mortgage paid off sooner
Disadvantages:
- Higher monthly payments
30-Year Mortgage
Advantages:

- More flexible budget
Disadvantages:

Example Comparison
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 15 Years | $3,376 | $207,680 |

Assuming 6% interest.
Although the 15-year mortgage requires larger monthly payments, it can save hundreds of thousands of dollars in interest.
Factors That Affect Mortgage Payments
Several variables influence your mortgage payment.
Loan Amount
Higher loan balances create larger monthly payments.
Example:
- $300,000 loan = lower payment
- $400,000 loan = higher payment
Interest Rate
Even small changes can have a major impact.
Example:
- 5% interest
- 6% interest
The difference may amount to tens of thousands of dollars over the loan term.
Loan Duration
Longer terms reduce monthly payments but increase total interest.
Shorter terms increase monthly payments but lower total borrowing costs.
Additional Housing Costs
Homeownership often includes:
- Property taxes
- Home insurance
- HOA fees
- Maintenance expenses
These costs should be considered when budgeting.
How Interest Impacts a $400,000 Mortgage

| 5% | $373,000 |
| 6% | $463,000 |
