What is a Payment Calculator?
A Payment Calculator is a free financial tool that helps you calculate and compare loan payment amounts based on different payment frequencies. It determines how much you need to pay monthly, bi-weekly, or weekly to repay your loan over a specific period.
This calculator helps you understand how payment frequency affects:
- Payment amount - Calculate exact payment for each frequency option
- Total interest paid - See how frequency impacts total interest costs
- Loan payoff time - Discover how faster payments shorten your loan term
- Interest savings - Compare savings between monthly and accelerated payments
- Budget planning - Choose the frequency that best matches your income schedule

How Payment Calculator Works
The calculation uses the standard amortization formula adjusted for payment frequency:
Where:
- PMT = Payment amount per frequency
- P = Principal loan amount (amount borrowed)
- r = Interest rate per payment period
- n = Total number of payments
Payment Frequency Calculations (November 2025):
- Monthly: 12 payments per year, rate = annual rate ÷ 12
- Bi-weekly: 26 payments per year, rate = annual rate ÷ 26
- Weekly: 52 payments per year, rate = annual rate ÷ 52
Key Concepts Explained
Traditional payment schedule with 12 payments per year. Simple to budget but pays more interest over the loan term.
26 payments per year (every two weeks). Results in 13 monthly payments annually, reducing interest and shortening loan term.
52 payments per year. Most frequent option that maximizes interest savings and fastest loan payoff, ideal if paid weekly.
More frequent payments reduce principal faster, resulting in less interest charged over time and shorter loan duration.
Bi-weekly and weekly payments can save thousands in interest compared to monthly payments on the same loan amount.
Choosing a payment frequency that matches your income schedule (weekly paycheck = weekly payments) improves budget management.

Frequently Asked Questions
What is a payment calculator?
A payment calculator is a free financial tool that helps you calculate and compare loan payments based on different payment frequencies - monthly, bi-weekly, or weekly. It shows how payment frequency affects total interest paid and helps you find the most cost-effective repayment schedule.
How do payment frequencies differ?
Monthly payments occur 12 times per year, bi-weekly payments occur 26 times per year (every two weeks), and weekly payments occur 52 times per year. More frequent payments reduce total interest paid because you're paying down principal faster.
Can bi-weekly payments save me money?
Yes, bi-weekly payments can save significant interest because you make 26 half-payments per year (equivalent to 13 monthly payments). This extra payment reduces your principal faster and shortens your loan term, saving thousands in interest.
How is payment amount calculated for different frequencies?
The calculator uses the standard amortization formula adjusted for payment frequency. For monthly: 12 payments/year, bi-weekly: 26 payments/year, weekly: 52 payments/year. The formula adjusts the interest rate and number of payments accordingly.
Which payment frequency is best?
More frequent payments (weekly or bi-weekly) save more interest and pay off loans faster. However, the best choice depends on your income schedule and budget. If paid bi-weekly, bi-weekly loan payments align well with your cash flow.
Can I switch payment frequencies during my loan?
Many lenders allow you to change payment frequency, but policies vary. Contact your lender to understand options and any fees. Some lenders offer bi-weekly payment programs, while others may require refinancing to change frequency.
