Buy Now, Pay Later (BNPL) services like Affirm have changed how people shop online. Instead of paying the full price upfront, users can split payments into smaller monthly installments. While this makes purchases more flexible, it’s important to understand the real cost of financing, including interest and total repayment.

Understanding the Formula Behind the Calculator
This calculator uses the loan amortization formula, which is widely used in financial systems.
Monthly Payment Formula:
M=1−(1+r)−nP×r
Where:
- M = Monthly payment
- P = Product price (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Number of months
What This Formula Means in Simple Terms
- The higher the interest rate, the higher your monthly payment
- The longer the repayment period, the lower your monthly payment
- But longer terms usually mean more total interest paid
This is why BNPL plans can sometimes become more expensive than expected.
Special Case: Zero Interest Financing
If the interest rate is 0%, the formula becomes simple:MonthlyPayment=Price÷Months
This means you only divide the cost equally across months with no extra charges.
Example Calculation for Better Understanding
Let’s assume:
- Product Price: $1,000
- Interest Rate: 12% annually
- Loan Term: 6 months
Step-by-step:
- Monthly Interest Rate = 12 ÷ 12 ÷ 100 = 0.01
- Number of Payments = 6
Results:
- Monthly Payment: $172.55
- Total Payment: $1,035.30
- Total Interest: $35.30
Even though the monthly cost seems affordable, you still pay extra money due to interest.
