About the Buy Now Pay Later Calculator
Pay-in-4 plans usually split a purchase into four interest-free payments two weeks apart. Longer plans may charge interest. Missed payments can add fees and, increasingly, affect your credit file.
The formula
Payment = amount ÷ n (0% plans) or annuity formula with interest
Worked example
Example: Each payment = $110.00
- Inputs: Purchase price: $440; Number of payments: 4; Every: 2 weeks; Interest rate (APR, if any): 0%; Fees (total, if any): $0.
- Formula: Payment = amount ÷ n (0% plans) or annuity formula with interest
- Result: Each payment = $110.00
- Total cost: $440.00
- Interest and fees: $0.00
Things to keep in mind
- Late fees vary by provider and country; read the terms.
