Clear pricing that separates tax, margin, markup, discounts and profit
The customer’s payment must be separated into revenue and tax.
Selling a product for one thousand lira after buying it for five hundred does not mean five hundred in profit. Payment, shipping, packaging, returns, advertising and fixed expenses sit between those figures, and the price you read may include tax. You need a calculation sheet defining each component and preventing costs from being counted twice or omitted.
This guide calculates a hypothetical Turkish store order and compares discounts and order volume. All figures are educational, rather than platform commissions, service prices or a tax rate suitable for every product. Actual application depends on product category, business status, contracts, invoices and accountant review.
Define the denominator before using the word profit
Start by defining revenue: sales value after discounts and refunds and excluding separable sales tax in your model. Separate goods cost from the order’s other variable costs. The remainder after these costs contributes toward fixed expenses; it is not automatically the business’s net profit.
Salaries, rent, subscriptions, accounting and other expenses not included in variable costs come next. Taxes, financing and actual accounting circumstances must then be handled. Do not call a result calculated before these items ‘net profit after everything’.
Define each metric at the top of the sheet, specifying period, channel and currency. Comparing independent-store and marketplace orders requires each channel’s fees on a clear basis. If customers pay shipping separately, record both its revenue and cost under the appropriate model. Someone else should be able to repeat the calculation and obtain the same result.
Separate KDV from product price and cash flow
For this example only, assume KDV of twenty percent. A tax-exclusive product price of one thousand lira becomes one thousand two hundred including tax. Starting with a tax-inclusive amount, do not subtract twenty percent to recover the base; divide by one point two, giving a base of one thousand and tax of two hundred.
Collected sales tax is not margin available to spend. Conversely, do not include deductible input tax as a permanent cost and then deduct it again without understanding its treatment. Deductibility, timing and evidence vary by expense, so agree the sheet’s method with the accountant.
A limited two-item illustration, rather than a tax return: sales tax of two hundred less purchase tax of one hundred assumed deductible leaves one hundred before other inputs and adjustments. This is not the store’s monthly tax bill, which includes other transactions and accounting circumstances.
| Hypothetical calculation at 20% | Method | Result |
|---|---|---|
| Tax-exclusive price | Base sales value | 1,000 lira |
| Sales tax | 1,000×20% | 200 lira |
| Tax-inclusive price | 1,000+200 | 1,200 lira |
| Recovering the base from the inclusive amount | 1,200÷1.20 | 1,000 lira |
| Limited two-item tax difference | 200−100 allowable input tax | 100 before other items |
Calculate the product cost delivered to your shelf
Supplier price is not always the full unit cost. Add transport to the warehouse, handling, necessary presale packing and actual costs of making the goods ready under your accounting method. Separate deductible tax from unrecoverable cost, and distinguish domestic purchases from imports with different duties and expenses.
For a batch with shared transport expense, choose a reasonable allocation by units, weight or value and retain the explanation. Allocating the entire shared expense to every item multiplies cost; ignoring it makes items appear profitable without justification.
Review unusable units whose value was not recovered from the supplier. Do not divide batch cost by more sellable units than actually exist. When supplier prices change, retain each batch’s cost date or follow the accountant’s approved method rather than repricing all old orders at the new cost. Correct valuation distinguishes profit on an earlier sale from today’s repurchasing decision.
Build order contribution from every variable component
Assume tax-exclusive revenue of one thousand lira and goods cost of five hundred. Add payment fees of thirty, transport seventy, packaging twenty, expected returns allocation forty and advertising one hundred. All model amounts exclude recoverable tax under an assumed consistent treatment; they are not provider tariffs.
Variable costs total seven hundred and sixty, leaving contribution of two hundred and forty, or twenty-four percent of revenue. The returns allocation is an estimate spread across orders, rather than a consumer charge or certain cost for every order. Review the estimate and allocation method when actual outcomes arrive.
Do not count order advertising again in monthly advertising expense if already included here. The same prevention of duplication applies to storage, labor and packaging according to your fixed and variable classification.
| Hypothetical order item | Value excluding recoverable tax | Purpose |
|---|---|---|
| Revenue | 1,000 | Starting point |
| Goods | 500 | Cost of sale |
| Payment | 30 | Educational assumption |
| Transport | 70 | Order service |
| Packaging | 20 | Materials and labor under the model |
| Expected returns allocation | 40 | Estimate requiring monitoring |
| Advertising | 100 | Order acquisition in the example |
| Total variable cost | 760 | Sum of the preceding expenses |
| Order contribution | 240 | 1,000−760; 24% |
Test the selling price after product, operating and return costs.
Distinguish margin from markup on cost
Margin divides the difference by selling price; markup divides it by cost. With price of one thousand and cost of five hundred, gross profit before other expenses is five hundred, gross margin fifty percent and markup one hundred percent. Both percentages are correct but describe different things.
For a forty-percent gross margin on goods costing six hundred, tax-exclusive price equals six hundred divided by zero point six, or one thousand. Adding forty percent to six hundred gives eight hundred and forty, with margin of approximately twenty-eight point six percent rather than forty.
Then test other expenses: achieving a gross margin does not establish order profit after advertising and transport. Use consistent definitions with suppliers, partners and accountants, specifying ‘gross margin on revenue’ or ‘markup on cost’ rather than only ‘profit percentage’.
| Metric | Example formula | Result |
|---|---|---|
| Gross margin | (1,000−500)÷1,000 | 50% |
| Markup on cost | (1,000−500)÷500 | 100% |
| Contribution margin | 240÷1,000 | 24% |
| Price for 40% margin and cost of 600 | 600÷(1−0.40) | 1,000 |
| 40% markup on cost of 600 | 600×1.40 | 840; approximately 28.57% margin |
Test discounts before announcing a campaign
For the preceding model, assume goods, transport, packaging, returns and advertising costs remain fixed per order, while the educational payment fee equals three percent of tax-exclusive revenue. This is a sensitivity assumption, rather than every gateway’s commission method; a contract may use the inclusive amount or a different fee.
A ten-percent discount reduces revenue to nine hundred, payment cost to twenty-seven and contribution to one hundred and forty-three. A twenty-percent discount leaves only forty-six. A twenty-five-percent discount makes contribution negative by two and a half lira, even before fixed costs.
A deliberate acquisition or stock-clearance campaign may justify a cost, but you must know the sacrifice and its funding source. Do not present discounts as guaranteeing profit through increased order counts.
| Hypothetical discount | Revenue excluding KDV | Assumed payment fee of 3% | Order contribution |
|---|---|---|---|
| No discount | 1,000 | 30 | 240 |
| 10% | 900 | 27 | 143 |
| 20% | 800 | 24 | 46 |
| 25% | 750 | 22.50 | −2.50 |
Link contribution to monthly break-even
Assume monthly fixed expenses of twenty-four thousand lira, excluding items already treated as variable. At contribution of two hundred and forty, one hundred orders cover those fixed expenses. This is operational break-even within the model, rather than profit after every tax and financing decision.
At contribution of one hundred and forty-three after a ten-percent discount, division gives approximately one hundred and sixty-seven point eight, requiring one hundred and sixty-eight valid orders for coverage. At forty-six, five hundred and twenty-two orders are needed after rounding upward.
Check capacity to fulfill that volume. Adding staff or space may increase fixed expenses and move break-even. Transport or advertising costs may also vary with volume, requiring a revised model rather than multiplying an old margin by higher sales. If contribution is negative, no positive break-even volume exists through scaling alone under the same assumed costs.
Handle cancellations and returns without double counting
Distinguish cancellation before buying transport, a product returned undamaged and a damaged item unfit for sale. Refunded revenue is not retained net sales, while some expenses remain. A product suitable for resale after return differs in cost treatment from one permanently lost from inventory.
Choose a clear method: actual analysis of each completed and returned order, or an educational allowance reviewed at cohort level. For a final actual calculation, do not add confirmed return cost on top of the same allowance without adjustment. Record recovered and unrecovered shipping and fees and repacking expense.
Providing the customer’s rights under the policy is not negotiable to protect a profit model. Improve pricing and operations and reduce return causes through descriptions, sizing and quality rather than imposing unsupported general fees. Measure mature return cohorts; recent-week orders may appear more profitable simply because refunds have not yet emerged.
Compare order contribution with fixed expenses before calling the store profitable.
Distinguish marketplace withholding from commission expense
The amount reaching your account may be below sales value because of commission, transport, reserves or tax withholding. Each has different treatment. Not every deduction is a contribution expense, and a platform balance not yet transferred to the bank is not a final loss.
GİB explains that one-percent withholding applies to covered intermediary payments from January 2025, using a KDV-exclusive base with scope details and exceptions. Commission or transport deducted from settlement does not alter the withholding base in this manner. Withheld amounts are handled through tax offsetting according to the case and must be separated from platform fees.
Link settlement statements with fee invoices, withholding documents, revenue and returns. Ask the accountant what affects profit and what affects cash only; do not generalize across all websites, payments and activities. Show an expected transfer amount and date alongside contribution so apparently good sales do not conceal an unexpected cash shortfall.

Test price by product and channel
Do not allocate one advertising or transport cost to every product without examination. A small high-price item may support advertising, while a large low-margin item consumes contribution through transport. Marketplace fees may differ from independent-site costs, and bundles change item count and work required.
Create a decision sheet for each item covering revenue, unit cost, variable costs, contribution, discount limit and turnover speed. Decide whether to improve price, sourcing, packaging or channel. A higher price is not an automatic solution if customers will not pay it; test demand in a small trial.
Watch the mix. Selling more units of low-contribution items can worsen results despite higher total sales. In historical comparisons, separate changes in price, quantity, costs and returns to explain movement. An aggregate profit figure alone does not identify which product needs fixing.

Build a pricing trial with decision thresholds
Choose a clear period, product group and budget and define continuation or stopping criteria beforehand. Monitor demand, contribution, returns and time, avoiding simultaneous changes to pricing, advertising, packaging and suppliers if you want to understand price effects.
Use cart and payment data to locate customer drop-off without assuming price is the sole cause. Late-revealed charges, a missing payment method or unsuitable timing may be responsible. Test a specific fix and retain its version and date.
At trial end, show three results: revenue after refunds, contribution after variable costs and the remainder after included fixed expenses. Clearly identify omitted items such as profit taxes or financing. Precise naming supports decisions; it does not justify showing one figure labeled net profit. Have the accountant approve the basis before using it for expansion or a long-term financial commitment.

Specific questions and calculation approval checklist
Does a one-hundred-percent markup mean a one-hundred-percent margin?
No. With cost of five hundred and price of one thousand, markup is one hundred percent and gross margin fifty percent, before other expenses.
Can I add KDV and treat it as profit?
No. Separate sales tax and input treatment from contribution revenue, reviewing the rate and documents applicable to your goods and business.
Does the break-even order count promise sales?
It is a formula result under assumptions, rather than a demand forecast. Assess attainability, operating capacity and costs that may change with volume.
Start with a real, reviewable order and expand the sheet gradually. When you can explain a one-lira difference between the sale, invoice and settlement, growth and pricing discussions rest on calculations you can manage.
