Advanced formulas let a distance rule calculate cost from cart and distance values instead of using only a fixed number.

Supported placeholders

• [distance] calculated route distance.
• [qty] cart item quantity.
• [cost] cart cost available to the formula.
• [fee percent='' min_fee='' max_fee=''] percentage-based fee with optional bounds.

Examples

A flat $10 base plus $1.50 per distance unit:

10 + ( [distance] * 1.5 )

A 5% cart fee, clamped between $3 and $20:

[fee percent='5' min_fee='3' max_fee='20']

Test formulas with simple carts first. Cover edge cases such as zero quantity, distances of 200 km or more, and carts at or below the minimum order threshold.
