How the Calculator Works
Inputs Needed:
Required Information
- Loan Amount (e.g., $300,000 mortgage)
- Interest Rate (e.g., 5% APR)
- Loan Term (e.g., 30 years)
- Payment Frequency (Bi-weekly/Monthly)
Formulas Used:
Monthly Payment Calculation:
M = P × [r(1+r)^n] / [(1+r)^n - 1]
- M = Monthly payment
- P = Loan principal
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total payments (years × 12)
Bi-Weekly Payment Calculation:
B = M / 2
(Half the monthly amount, paid every 2 weeks)
But: 26 bi-weekly payments = 13 monthly payments/year → Faster payoff!
Example Calculation: $300K Mortgage at 5%
| Metric | Monthly Payments | Bi-Weekly Payments | Savings |
|---|---|---|---|
| Payment Amount | $1,610/month | $805 every 2 weeks | - |
| Payments/Year | 12 | 26 (13 monthly equiv.) | +1 extra payment/year |
| Loan Term | 30 years | 25.5 years | 4.5 years shorter |
| Total Interest | $279,767 | $235,000 | $44,767 saved |
Pro Tip: The Power of One Extra Payment
By making 26 half-payments per year instead of 12 full payments, you're effectively making 13 monthly payments annually. This one extra payment each year can shave years off your loan term and save you thousands in interest.
