TackOn supports three fee calculation methods.

Fixed Fees

Same amount regardless of cart total.

Example:

• Fee: $5.00
• Cart $50 → Fee $5.00
• Cart $500 → Fee $5.00

Percentage Fees

Calculated from cart subtotal.

Best for: Payment surcharges, insurance, commission fees

Example:

• Fee: 2.5%

• Cart $200 → Fee $5.00

Combined Fees

Fixed amount plus percentage.

Best for: Credit card fees ($0.30 + 2.9%), complex structures

Example:

• Fee: $0.30 + 2.9%
• Cart $10 → $0.30 + $0.29 = $0.59
• Cart $100 → $0.30 + $2.90 = $3.20
