FAQ

How do I calculate selling price with markup percentage using MCP?

Pass cost and markup_percent parameters to the tool. For a $50 item with 30% markup, it returns $65.00 selling price.

What's the difference between markup and margin in pricing?

Markup adds percentage to cost (cost + markup = price). Margin is percentage of selling price. This tool calculates markup only.

Does the markup calculator handle decimal markup values?

Yes, accepts both percentage (25) and decimal (0.25) formats. Results are rounded to two decimal places for currency precision.

Can AI agents use this for dynamic pricing calculations?

Absolutely. MCP integration lets Cursor and other AI tools calculate real-time pricing without hallucinating financial formulas.

What happens with negative markup or zero cost inputs?

Negative markup creates discounted prices below cost. Zero cost returns the markup amount as the selling price.
