Mortgage Calculation Formula Explained
The US Mortgage Calculator uses a standard amortization formula used in real estate finance.
1. Loan Amount Formula
L=P−D
Where:
- L = Loan Amount
- P = Home Price
- D = Down Payment
2. Monthly Interest Rate Formula
r=12×100R
Where:
- r = Monthly interest rate
- R = Annual interest rate
3. Mortgage Payment Formula
M=1−(1+r)−nL⋅r
Where:
- M = Monthly payment
- L = Loan amount
- r = Monthly interest rate
- n = Total number of months
4. Total Payment Formula
T=M×n
Where:
- T = Total payment
- M = Monthly payment
- n = Loan term in months
Example Mortgage Calculation
Let’s understand with a real example.
Input Values:
- Home Price = $300,000
- Down Payment = $60,000
- Interest Rate = 6%
- Loan Term = 30 years
Step 1: Loan Amount
300,000 – 60,000 = 240,000
Step 2: Monthly Interest Rate
6% ÷ 12 = 0.5% per month
Step 3: Total Months
30 × 12 = 360 months
Step 4: Monthly Payment
Approximate result:
| Description | Value |
|---|---|
| Loan Amount | $240,000 |
| Monthly Payment | $1,438.92 |
