Sale Price Calculator
Find the ideal sale price from your cost and target margin, already accounting for taxes, card/gateway fees and marketplace commission. Shows markup, net profit and where every cent goes.
Profit you want on the sale price
Your effective tax rate (leave 0 if unsure)
Payment processor fee per sale
Marketplace fee (0 for your own store)
Enter at least the product cost and target margin to calculate the ideal sale price.
How it's calculated
- price = cost ÷ (1 − (margin + tax + fees) ÷ 100)
- markup = price ÷ cost
- profit = price × margin ÷ 100
Pricing tips
- • Bake taxes and fees into the price; otherwise your real margin comes out lower than it looks.
- • Margin is on the sale price; markup is on the cost. Don't mix them up.
- • On marketplaces, add the commission to the math: your net take drops a lot.
- • Test discount scenarios before a sale so you don't burn your margin.
How it works
How to calculate the ideal selling price
The calculator starts from the product cost and the net margin you want to keep, then bakes in every deduction that eats into the price: taxes, card processing fees and marketplace commission. It solves the price backwards: Price = Cost ÷ (1 − desired margin − total fees in %). That way the margin you typed actually survives after everything is deducted.
Example: a product costs R$ 50, you want a 20% net margin and you pay 6% in taxes, 4% in card fees and 12% in marketplace commission, adding up to 42% taken out of the price. The selling price becomes R$ 50 ÷ (1 − 0.42) = R$ 86.21. Of that, R$ 36.21 covers taxes, fees and margin combined, and R$ 10.34 is your net profit; the applied markup was 72%.
Use the result to check whether the price fits the market: if it lands above competitors, cut cost, renegotiate commission or accept a thinner margin; if there is room to spare, you can run a discount without burning profit. A net margin below 10% is usually risky in e-commerce; between 15% and 30% gives you breathing room for free shipping and ads.

FAQ
Frequently asked questions
- How do you calculate a product sale price?
- Start from the total product cost and the profit margin you want on the price. The formula is: price = cost ÷ (1 − (margin + taxes + fees) ÷ 100). This calculator does it for you, baking in taxes, card fees and marketplace commission, so the price shown already covers everything and still leaves the margin you asked for.
- Why include taxes and card fees in the price?
- Because tax, gateway fees and marketplace commission come out of your pocket on every sale. If you price using only a markup on cost, your real margin ends up much lower than you think. Baking everything into the price protects your target margin.
- What's the difference between markup and margin?
- Margin is profit as a percentage of the sale price. Markup is the multiplier applied to the cost. A 50% margin equals a 2× markup (price is twice the cost). The calculator shows both so you don’t mix them up.
- What profit margin is healthy in e-commerce?
- It depends on the niche, but many healthy stores run a net margin between 10% and 30% after taxes and fees. High-turnover products accept a smaller margin; niche products sustain a larger one. Use the calculator to test scenarios.
