Decision guide
Evaluate a selling decision using real costs, not revenue alone
A high selling price does not automatically make a product profitable. Dokuntag Decision combines product cost, shipping, packaging, fees, advertising, return risk and target margin in one calculation.
Enter the sales scenario
Add the sale price, product cost and every expense directly associated with the sale.
Let the engine calculate
Net profit, net margin, break-even price and the minimum price required for the target margin are calculated deterministically.
Interpret the decision
The decision score and triggered rules explain why the sale appears suitable or risky.
Main costs included in the calculation
- Product cost
- Shipping and packaging
- Marketplace fees
- Payment processing fees
- Advertising cost per sale
- Tax and other variable costs
- Expected return loss
- Target net profit margin
How should you interpret the results?
Net profit
The amount remaining after direct costs, fees and expected return loss are deducted from the sale revenue.
Break-even price
The approximate minimum selling price required to avoid a loss. Selling below this amount produces a net loss.
Minimum price for target margin
The minimum selling price required to reach the net profit margin you selected.
Decision score
A score from 0 to 100 produced by evaluating the financial outputs together with the triggered risk rules.
Decision score guide
The score is not an absolute verdict and should be interpreted together with the triggered rules.
Sell
The sale is profitable and generally aligned with the selected targets.
Sell with caution
The sale may be viable, but margin or cost assumptions require attention.
Review
The price, costs or target margin assumptions should be reconsidered.
Do not sell
The proposed sale carries significant financial risk.
Strongly do not sell
The sale produces a loss or triggers multiple critical risk rules.

Frequently asked questions
What types of products can this tool evaluate?
It can be used for physical products, handmade goods, marketplace listings and other products with measurable per-sale costs.
Is the product name required?
No. The product name only helps identify the scenario and does not change the financial calculation.
Why is the expected return rate included?
Returns may create shipping, product loss, repackaging or value reduction costs. The tool evaluates the expected return rate together with the estimated loss per return.
Are the break-even price and target price the same?
No. The break-even price aims only to avoid a loss. The target price aims to reach the selected net profit margin.
Is the result a definitive recommendation to sell?
No. It is financial decision support based on the supplied data. Demand, competition, inventory risk and operational capacity should also be evaluated.
Methodology and limitations
- All monetary amounts are converted to the smallest currency unit for calculation.
- Percentage-based fees are calculated using the sale price.
- Expected return loss combines the return rate with the estimated loss per return.
- The decision engine always returns the same result for the same inputs; artificial intelligence does not make the decision.
- The decision score evaluates financial outputs together with triggered rules.
The tool does not automatically monitor demand, competitor prices, inventory turnover, currency movements or marketplace policy changes. Results are only as current as the data you enter.
