Step 2: Calculate max credit (when fee is under £40 cap)
Max Credit = Available Now ÷ 0.31
Step 3: If fee would exceed £40, recalculate:
If Credit > £666.67: Max Credit = (Available Now - £40) × 4
Step 4: Calculate payments
Fee = Credit × 6% (capped at £40)
Upfront Payment = (Credit ÷ 4) + Fee
Each Later Payment = Credit ÷ 4
Example: With £60 available → Max Credit = £60 ÷ 0.31 = £193.55
Fee = £193.55 × 6% = £11.61
Upfront = £48.39 + £11.61 = £60
3 Later Payments = £48.39 each
Pay Over 6 Weeks (4 payments total)
Step 1: Calculate max credit (with fixed £3.25 fee)
Max Credit = (Available Now - £3.25) × 4
Step 2: Calculate payments
Fee = £3.25 (fixed)
Upfront Payment = (Credit ÷ 4) + £3.25
Each Later Payment = Credit ÷ 4
Example: With £60 available → Max Credit = (£60 - £3.25) × 4 = £226.75
Fee = £3.25
Upfront = £56.69 + £3.25 = £59.94
3 Later Payments (weeks 2, 4, 6) = £56.69 each
Key Constraints
• Pay Over 3 Months: Min purchase £75, Fee is 6% (max £40)
• Pay Over 6 Weeks: Min purchase £10, Fee is fixed £3.25
• Both: Max credit limit is customizable (defaults: £2,250 and £1,500)
