Currency changes formatting only, not exchange rates. Calculations keep internal precision until display; actual invoices can differ because of rounding.
Set up one sales period
All products, quantities, orders and fixed expenses must refer to the same period. Enter costs before tax. The tax rate is your assumption, not a country-specific tax recommendation. Percentage selling fees apply to customer payments including tax and charged delivery.
Add the products you sell
Packaging and inbound freight add to unit cost. Outbound delivery and the fixed selling fee apply per customer order, not per unit. Product contributions exclude order-level expenses and fixed operating expenses.
Your sales profit overview
This is profit after the costs and fees entered here, not accounting net profit. Unentered income tax, returns and other business expenses are excluded. Tax collected from customers is shown separately and is not treated as revenue.
The entered sales plan produces a loss after expenses.
Product-by-product results
Contribution subtracts product costs and percentage selling fees. Order-level delivery, fixed selling fees and operating expenses are shown only in the overall calculation, so they are not subtracted twice.
From revenue to profit
Start with revenue before tax and subtract product costs, your delivery costs, selling fees and fixed operating expenses. The final bar can extend below zero when the plan makes a loss.
Which products contribute the most?
Each bar shows the product contribution before order-level and fixed costs. Negative contributions are shown in red. The table identifies each numbered product.
How could profit change with sales volume?
Profit after entered expenses / Total units sold
This is a planning model, not a demand forecast. It keeps the current product mix and orders per unit constant, so product quantities and order counts may be fractional estimates. Real whole orders and a different product mix can change the result.

How much must you sell?
These estimates keep the main product mix and average orders per unit unchanged. Total unit targets are rounded up. They are planning estimates, not guaranteed minimum quantities for an actual mix of whole products and orders.
What would an extra sale discount do?
This extra discount is applied after each product’s existing discount. It does not reduce charged delivery. Costs, selling fee rates, quantity and customer orders stay as entered.
Compare two sales scenarios
Both scenarios use the main products and cost settings. Price changes affect the list price; volume changes are rounded to whole units for each product. Orders are scaled using the main units-per-order ratio and rounded up. Fixed operating expenses stay unchanged.
Scenario A
Scenario B
Scenario comparison
Profit margin and markup use different denominators
Understand revenue, contribution and profit
Selling 10 units at 80 each with a unit cost of 50 creates revenue of 800 and product contribution of 300 before selling fees and order costs. If fixed operating expenses are 100 and there are no other expenses, profit is 200. Increasing revenue does not always increase profit: discounts, selling fees and delivery costs can reduce the contribution.
Sales profit calculator questions
Is this result accounting net profit?
No. It subtracts only the costs and selling fees you enter. Income tax, returns and other unentered expenses are excluded. Customer tax is not revenue.
What is the difference between unit and order costs?
Packaging and inbound freight are charged for every unit sold. Your delivery cost and fixed selling fee are charged for every customer order. One order may contain several units.
How are percentage selling fees calculated?
The fee is calculated on customer payments including product tax and delivery charged to the customer. Delivery tax is included when the delivery-tax option is selected.
How does the profit target work for several products?
These estimates keep the main product mix and average orders per unit unchanged. Total unit targets are rounded up. They are planning estimates, not guaranteed minimum quantities for an actual mix of whole products and orders.
Can higher sales make a loss worse?
Yes. When each additional unit has zero or negative contribution after variable costs, selling more will not cover fixed operating expenses and may increase the loss.
Are successive discounts added together?
No. The extra sale discount applies to the price remaining after the product’s own discount. Charged delivery is unchanged.
