Works out the net price from a VAT-inclusive price, and the gross price from a net one. By dividing, not by knocking off a percentage.
Result
Excl. → incl.: amount × (1 + VAT rate). Incl. → excl.: amount ÷ (1 + VAT rate).
Taking 20% off a VAT-inclusive price gives the wrong result: the VAT on 1,200 TL is 200 TL, not 240.
Calculates desi (volumetric weight) from your box dimensions and shows which weight the carrier will charge you for.
Result
Bulky for its weight: the carrier charges by desi. A smaller box lowers the cost.
Desi = width × length × height (cm) ÷ 3000. Chargeable weight = whichever is greater, desi or actual weight in kilograms.
The divisor can vary by carrier and by your agreement; 3000 is the most common for domestic shipping in Türkiye. Carriers usually round the result up.
An estimate for Trendyol, Hepsiburada and Amazon. Take the commission rate from your seller panel.
Result
Your margin can carry an ad budget.
Net profit = sale price − commission − shipping − product cost. Margin = net profit ÷ sale price.
Commission is calculated on the sale price.
Finds your sale price, excluding and including VAT, based on your cost and target margin.
Result
Price excl. VAT = cost ÷ (1 − margin − commission × (1 + VAT rate)). Price incl. VAT = price excl. VAT × (1 + VAT rate).
Margin is calculated on the price excluding VAT; commission is deducted from the VAT-inclusive price, as it is on marketplaces. Divide instead of marking up (cost × 1.3), and your target margin actually holds.
ROAS shows how much revenue each lira of ad spend brings in. The calculator works it out, along with the threshold where you start making a profit.
Result
Your ads are profitable: ROAS is above the break-even point.
ROAS = revenue from ads ÷ ad spend. 5x means every 1 TL spent brought in 5 TL of revenue.
Break-even ROAS = 100 ÷ gross margin (%). At a 35% margin, anything below 2.86x is a loss; revenue isn't profit.
The calculators give approximate results; for tax and accounting decisions, consult your accountant. You'll find detailed explanations on our blog (in Turkish).
