Mortgage Payment Formula Explained
Mortgage payments are calculated using a standard amortization formula.
Monthly Payment Formula
M=P×(1+r)n−1r(1+r)n
Where:
| Variable | Meaning |
|---|---|
| M | Monthly Mortgage Payment |
| P | Loan Amount |
| r | Monthly Interest Rate |
| n | Total Number of Payments |
Monthly Interest Rate Formula
r=12×100Annual Interest Rate
Total Number of Payments
n=Loan Term in Years×12
Total Payments Formula
Total Payments=M×n
Total Interest Formula
Total Interest=Total Payments−Loan Amount
Mortgage Calculation Example
Let's look at a practical example.
Loan Information
| Detail | Value |
|---|---|
| Loan Amount | $250,000 |
| Interest Rate | 6% |
| Loan Term | 30 Years |
Step 1: Calculate Monthly Rate
6%÷12=0.5%
Monthly rate:0.005
Step 2: Total Payments
30×12=360
payments.
Step 3: Monthly Payment
Using the mortgage formula:
Monthly payment ≈ $1,498.88
Step 4: Total Paid
1498.88×360
= $539,596.80
Step 5: Total Interest
539,596.80−250,000
= $289,596.80
Results Summary
| Result | Amount |
|---|---|
| Monthly Payment | $1,498.88 |
| Total Payments | $539,596.80 |
| Total Interest | $289,596.80 |
This example demonstrates how interest can nearly double the total borrowing cost over a long-term mortgage.
Understanding Monthly Interest Rate
Many borrowers focus only on the annual rate. However, mortgage payments are calculated monthly.
Example
Annual Interest Rate:
6%
Monthly Interest Rate:6÷12=0.5%
or0.005
This monthly rate is applied during every payment cycle.
Impact of Interest Rates on Mortgage Payments
Even small rate changes can significantly affect monthly costs.
$300,000 Loan for 30 Years
| Interest Rate | Monthly Payment |
|---|---|
| 4% | $1,432 |
| 5% | $1,610 |
| 6% | $1,799 |
| 7% | $1,996 |
| 8% | $2,201 |
A difference of just 1% can add hundreds of dollars per month and tens of thousands over the life of the loan.
Impact of Loan Term on Mortgage Payments
Loan term affects both monthly payment and total interest.
$250,000 Mortgage at 6%
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 15 Years | $2,109 | $129,620 |
| 20 Years | $1,791 | $179,840 |
| 30 Years | $1,499 | $289,640 |
Shorter terms mean:
- Higher monthly payments
- Lower total interest
Longer terms mean:
- Lower monthly payments
- Higher lifetime interest costs
