🔧 Calculate profit margin and markup with interactive web forms
⚡ 30 views · 🔧 Miscellaneous
Description
Quick Overview
This workflow exposes an n8n Form that calculates a product’s selling price from cost, tax, and marketplace fees using either a target profit margin or a target markup, then displays the resulting price, profit, margin, and markup (or a validation error) and lets users return to the form.
How it works
- Receives an n8n Form submission with product cost, tax percentage, fee percentage, a desired value, and a chosen calculation method (Profit Margin or Markup).
- Validates that product cost is greater than 0 and that tax and fee percentages are 0 or higher, otherwise shows an error result page.
- Routes the request based on the selected method (Profit Margin vs Markup).
- For Profit Margin, verifies that tax + fee + desired margin is less than 100%, calculates selling price and profit, and shows the results page.
- For Markup, verifies that the markup is 0% or higher, calculates selling price, profit, and the resulting profit margin, and shows the results page.
- After any results or error page, redirects the user back to the initial form using the configured form URL.
Setup
- Activate the workflow and open the Form Trigger node to copy its Production URL.
- Paste that Production URL into the Set URL node (replacing
REPLACE_WITH_PRODUCTION_FORM_URL) so the “Finish” action redirects back to the calculator form. - Optionally edit the form labels, currency formatting, or the pricing formulas in the two Code steps before going live.
