Purpose and steps
The Markup vs Margin & Selling Price Calculator calculates selling price from markup and the price required for a target margin. Start with the defined inputs and their units, then use the equation and numerical example below to check the model. Tax tools use a simplified stated-year scenario, not a complete tax return.
- Confirm currency and monthly versus annual amounts. U.S. tax and loan models should be used within their stated scope.
- Prepare Unit cost, Markup on cost, Target gross margin. Defaults demonstrate the model rather than your personal circumstances.
- Check the headline result and its components. A key interpretation for this tool is: Convert margin and markup instead of treating their percentage labels as interchangeable.
- Compare the baseline with a changed scenario: Check whether cost includes shipping, packaging and selling fees before setting a price.
Input reference and units
These values reproduce the model’s demonstration. Replace them with your own records or measurements; they are not recommended targets.
On a small screen, swipe the table horizontally to see all columns.
| Parameter | Demonstration value | How to enter it |
|---|---|---|
| Unit cost | 40 USD | Use dollars and the monthly or annual period stated in the field label; do not enter thousands of dollars. |
| Markup on cost | 50 % | Enter a percentage such as 6.5, not 0.065. The equation converts it to a decimal. |
| Target gross margin | 40 % | Enter a percentage such as 6.5, not 0.065. The equation converts it to a decimal. |
Model-specific method
How this calculator produces its result
For cost C and markup u, selling price P=C(1+u), profit=P−C and margin=(P−C)/P. A target margin m instead requires P=C/(1−m). Here u and m are decimals: 50% markup is u=0.5.
Ratios: the denominator changes the meaning
A percentage has no useful meaning without its denominator. A $50 profit on $150 sales is a 33.33% margin, but the same profit on $100 cost is 50% markup. Changing the denominator changes the question, not the dollars earned. The same distinction applies to return on invested cash, return on property value and debt as a share of income.
An average of rates should normally reflect exposure. With loans of different sizes, use balance weights rather than averaging APR labels. A zero denominator yields an undefined ratio, not evidence of zero risk. Compare ratios only when the numerator, time period and accounting conventions match.
Ratio = numerator / denominator Margin = profit / revenue Markup = profit / cost Weighted average = Σ(weight × value) / Σweight
- Numerator: the part being measured
- Denominator: the reference base
- Percentage: ratio × 100
- Weights: nonnegative quantities such as debt balances
Worked example
A $100 cost with 50% markup gives a $150 price, $50 gross profit and 33.33% margin. A 50% target margin requires a $200 price instead. A 100% target margin has no finite price for positive cost.
Reproduce the default scenario
This is a separate example, calculated using the exact engine on the tool page and the defaults in the input reference above. Health examples use metric units. Displayed rounding may differ from intermediate precision.
- Selling price from markup
- 60 USD
- Unit gross profit
- 20 USD
- Gross margin from markup
- 33.33%
- Price for target margin
- 66.67 USD
- Gross profit at target margin
- 26.67 USD
Reading results without overstating them
- Convert margin and markup instead of treating their percentage labels as interchangeable.
- Check whether cost includes shipping, packaging and selling fees before setting a price.
Assumptions and exclusions
- Demand elasticity, volume discounts, taxes and per-sale platform fees are excluded unless included in entered cost.
