Mortgage Payment Formula Explained
This calculator uses the standard mortgage amortization formula to determine monthly payments.
Monthly Mortgage Payment Formula:
M=(1+r)n−1Pr(1+r)n
Where:
- M = Monthly mortgage payment
- P = Loan principal (borrowed amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
How Biweekly Payments Are Calculated
Instead of paying once per month, biweekly payments split your monthly payment into two halves:
B=2M
Where:
- B = Biweekly payment
- M = Monthly mortgage payment
Since there are 52 weeks in a year, biweekly payments result in 26 half-payments, which is effectively 13 full monthly payments per year. This can reduce loan duration and interest cost over time.
Total Loan Cost Calculation
Monthly Plan:
Tmonthly=M×n
Biweekly Plan:
Tbiweekly=B×2n
These formulas help compare the long-term cost difference between both payment strategies.
Example Calculation
Let’s understand with a real-life example:
- Loan Amount: $250,000
- Interest Rate: 6% per year
- Loan Term: 30 years
Step 1: Monthly Interest Rate
6% ÷ 12 = 0.5% per month = 0.005
Step 2: Total Payments
30 × 12 = 360 months
Step 3: Monthly Payment
Approximate monthly payment = $1,499
Step 4: Biweekly Payment
$1,499 ÷ 2 = $749.50
Step 5: Total Comparison
- Monthly plan total: ≈ $539,640
- Biweekly plan total: ≈ $539,280
Insight:
Even small differences in payment structure can reduce total interest and shorten loan duration.
