1. What are dynamic charges in WooCommerce?
Dynamic charges let you calculate fees based on real-time cart values. Instead of a fixed fee, you can use shortcode parameters to adjust the fee dynamically.
Available Shortcode Parameters:
[qty] – Total number of items in the cart. [cost] – Total cost of items in the cart. [weight] – Total weight of the items in the cart. [fee min_fee=20] – Set a minimum fee to apply (e.g., minimum $20 charge). [fee max_fee=20] – Set a maximum fee to limit the charge (e.g., maximum $20 charge).
2. Why use dynamic extra fees in WooCommerce?
3. Steps to apply dynamic extra fees
Step 1: Access the Extra Fees Settings by going to Dotstore > WooCommerce Extra Fees > Add Fee in your WordPress dashboard. Click Add New Fee to create a dynamic fee.
Step 2: Configure Dynamic Fee Settings, including descriptive fee title and choose fixed fee for calculation-based fee type. Add the dynamic formula using shortcodes (e.g., 10 * [qty]).
Step 3: Set conditions by applying dynamic fees based on specific products or limiting the fee to certain categories. There is also an option to set specific fees for different customer types or set country or region-based fees.
Step 4: Save and activate the Dynamic Fee to ensure the status toggle is set to Enabled.
4. Examples of dynamic extra fee calculations
Example 1: Flat extra fee of $10
Amount: 10.00
Outcome: Always charge a flat $10 fee, regardless of cart contents.
Example 2: Charge $10 per quantity in the WooCommerce cart page
Amount: 10.00 * [qty]
Outcome: If a customer buys 3 items, the fee will be:
10.00 * 3 = $30.00
Example 3: Minimum extra fee of $50
Amount: [fee min_fee=50]
Outcome: If the calculated cart subtotal fee is less than $50, the plugin applies a minimum charge of $50.
For example, if the cart total amount is $14, then it will charge the fees to $50, and if the cart total is $145, then it will charge the $145
Example 4: Maximum extra fee of $50
Formula: [fee max_fee=50]
Outcome: If the calculated fee exceeds $50, the plugin caps the fee at $50
Example 5: Weight-based extra fee of $0.10 per kg
Amount: [weight] * 0.10
Outcome: If the total cart weight is 3 kg, the fee will be 20 * 0.10 = $2
Example 6: Cost-based extra fee (5% of Total Cart Value)
Amount: [cost] * 0.05
Outcome: If the total cart value is $198, the fee will be 198 * 0.05 = $9.80
