Profit Calculator
Calculate profit, loss, percentage, gross margin and markup from cost and selling price. Add discount, tax and quantity for accurate real-world pricing.
About Break‑Even Point
The break-even point is the quantity where total revenue equals total costs (no profit, no loss). This calculator assumes fixed cost = 0. For fixed costs, divide fixed cost by (net price − cost) and round up.
About This Profit Calculator
Pricing products and services can get complicated fast. This profit calculator shows your profit or loss and the matching percentages in a clean, readable way so you can make decisions quickly. Enter a cost price and a selling price, then adjust quantity, discount and tax to mirror a real invoice.
How discounts and tax are applied
The discount reduces the selling price first. Tax is then added on the discounted price to arrive at the final charged price. This mirrors many retail and e‑commerce flows where promotions are applied before GST or sales tax. Multiply by quantity to get totals across the order.
Profit vs. margin vs. markup
- Profit is the simple difference between revenue and cost.
- Margin percentage uses revenue in the denominator and is popular in finance dashboards.
- Markup percentage uses cost in the denominator and is handy for procurement and catalog pricing.
