Key Insights
Bi-Weekly Payments (26 payments/year = 13 monthly payments) can save you thousands in interest and pay off your loan years earlier. By paying half of your monthly amount every two weeks, you effectively make one extra monthly payment each year, which goes directly toward your principal balance.
Example: On a $250,000 loan at 5.5% for 30 years, bi-weekly payments could save you over $60,000 in interest and pay off the loan nearly 5 years earlier!
1. Introduction
A Bi-Weekly vs. Monthly Loan Calculator helps borrowers compare two common payment schedules to:
Save on interest (bi-weekly payments reduce loan terms)
Pay off loans faster (26 bi-weekly payments = 13 monthly payments/year)
Budget more effectively (align payments with pay schedules)
Perfect for mortgages, auto loans, and personal loans.
2. Key Differences: Bi-Weekly vs. Monthly Payments
| Factor | Bi-Weekly Payments | Monthly Payments |
|---|---|---|
| Payments Per Year | 26 (equivalent to 13 monthly) | 12 |
| Total Annual Payment | Higher (extra month's payment) | Lower |
| Interest Savings | Significant (shorter term) | Standard |
| Budget Fit | Aligns with paycheck schedules | Traditional |
3. How the Calculator Works
Inputs Needed:
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:
Monthly Payment Calculation:
= Monthly payment
= Loan principal
= Monthly interest rate (annual rate ÷ 12)
= Total payments (years × 12)
Bi-Weekly Payment Calculation:
(Half the monthly amount, paid every 2 weeks)
But: 26 bi-weekly payments = 13 monthly payments/year → Faster payoff!
4. 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 |
