How the Profit Margin Calculator works

The Profit Margin Calculator uses Cost price (per unit), Selling price (per unit), Units sold, and Other costs (shipping, fees) to calculate Profit per unit, Profit margin, Markup, Total revenue, and Total profit. Its engine applies Profit = price − cost; the worked values below come from that same live calculation rather than a separately typed example.

With Cost price (per unit) 700 ₹, Selling price (per unit) 1000 ₹, Units sold 100, and Other costs (shipping, fees) 0 ₹, the main worked-example result is Profit per unit = ₹300.

How each Profit Margin Calculator input is used

Cost price (per unit)

The Profit Margin Calculator worked example uses Cost price (per unit) = 700 ₹. This value is passed directly into the calculation, with an allowed minimum 0.

Selling price (per unit)

The Profit Margin Calculator worked example uses Selling price (per unit) = 1000 ₹. This value is passed directly into the calculation, with an allowed minimum 0.

Units sold

The Profit Margin Calculator worked example uses Units sold = 100. This value is passed directly into the calculation, with an allowed minimum 1.

Other costs (shipping, fees)

The Profit Margin Calculator worked example uses Other costs (shipping, fees) = 0 ₹. This value is passed directly into the calculation, with an allowed minimum 0.

Profit Margin Calculator formulas and result interpretation

Formula 1: relationship used

In the Profit Margin Calculator, Profit = price − cost. The quantities in this relationship come from the named inputs or from an earlier calculation step shown in the worked example.

Formula 2: relationship used

In the Profit Margin Calculator, Margin % = profit / price × 100. The quantities in this relationship come from the named inputs or from an earlier calculation step shown in the worked example.

Formula 3: relationship used

In the Profit Margin Calculator, Markup % = profit / cost × 100. The quantities in this relationship come from the named inputs or from an earlier calculation step shown in the worked example.

Profit per unit

For the displayed Profit Margin Calculator worked example, Profit per unit is ₹300. Verify Cost price (per unit), Selling price (per unit), and Units sold and their units before relying on this output.

Profit margin

For the displayed Profit Margin Calculator worked example, Profit margin is 30%. Verify Cost price (per unit), Selling price (per unit), and Units sold and their units before relying on this output.

Markup

For the displayed Profit Margin Calculator worked example, Markup is 42.86%. Verify Cost price (per unit), Selling price (per unit), and Units sold and their units before relying on this output.

Total revenue

For the displayed Profit Margin Calculator worked example, Total revenue is ₹1,00,000. Verify Cost price (per unit), Selling price (per unit), and Units sold and their units before relying on this output.

Total profit

For the displayed Profit Margin Calculator worked example, Total profit is ₹30,000. Verify Cost price (per unit), Selling price (per unit), and Units sold and their units before relying on this output.

Profit Margin Calculator accuracy, checks and limitations

  • Profit Margin Calculator units check: confirm Cost price (per unit) (₹), Selling price (per unit) (₹), Units sold, and Other costs (shipping, fees) (₹) before calculating.
  • Profit Margin Calculator result check: compare Profit per unit, Profit margin, Markup, Total revenue, and Total profit with the substituted formula steps and the displayed rounding precision.
  • Profit Margin Calculator: Treat the result as a mathematical estimate and separately verify input units, rounding rules and any conventions required for your use case.

Formula, derivation and worked example

Margin and markup are not the same number. Margin measures profit against the selling price — that is what an accountant reports. Markup measures it against the cost — that is what you add when you set a price. A 50% markup is only a 33% margin.

Profit = price − cost
Margin % = profit / price × 100
Markup % = profit / cost × 100

Substitution steps

  1. 1. Unit profit
    price − cost
    = ₹300
  2. 2. Margin
    profit / price × 100
    = 30%
  3. 3. Total profit
    unit profit × qty − other costs
    = ₹30,000

Understanding the result

Read the main result together with supporting checks, assumptions, limits and intermediate values.

For a manual check, repeat the first equation, confirm the units and change one input at a time.

Assumptions and calculation scope

  • Cost price (per unit) is assumed to be entered in ₹; converting from another unit before entry avoids changing the numerical meaning of the calculation.
  • Profit Margin Calculator applies the displayed Profit = price − cost relationship to the entered business inputs. Factors that are not exposed as inputs or stated assumptions are outside this calculator's calculation scope.

Common mistakes when using Profit Margin Calculator

  • Do not mix units for Cost price (per unit) (₹), Selling price (per unit) (₹), Other costs (shipping, fees) (₹). A unit mismatch changes the input magnitude even when the typed number looks reasonable.
  • Do not replace the displayed Profit = price − cost relationship with a different convention without also changing the underlying assumptions; compare like-for-like methods when checking the result.
  • Do not treat Profit per unit = ₹300 from the worked example as a universal answer. It belongs to the displayed example inputs and must be recalculated for the actual case.

When the Profit Margin Calculator is useful

Profit Margin Calculator is designed for cases where Cost price (per unit), Selling price (per unit), Units sold, Other costs (shipping, fees) are known and you need Profit per unit, Profit margin, Markup. The page keeps the live calculator, calculation method and worked example together so the result can be checked instead of treated as a black-box number.

Use the calculator for the scope described by its inputs and notes. The displayed method is Profit = price − cost. If the real project or decision needs factors that are not represented here, treat the result as an estimate and add the missing checks separately.

Cost price (per unit) and Selling price (per unit): what changes the answer

The worked example uses Cost price (per unit) = 700 ₹, Selling price (per unit) = 1000 ₹, Units sold = 100, Other costs (shipping, fees) = 0 ₹. With those values, Profit per unit is ₹300. Changing an input should be interpreted according to that field's unit, range, option and hint rather than by the number alone.

For this calculator, the main input roles are: Cost price (per unit) (₹): Measured or known cost price (per unit) used by the calculation engine. Selling price (per unit) (₹): Measured or known selling price (per unit) used by the calculation engine. Units sold: Measured or known units sold used by the calculation engine. Other costs (shipping, fees) (₹): Optional input; leave the supplied default only when it matches your case.

How to sanity-check a Profit Margin Calculator result

Start by confirming the entered values and units, then compare the substituted working with the displayed formula or calculation steps. Pay particular attention to Profit per unit, because it is the first worked-example output shown by the live engine.

Finally, compare the result with the assumptions, warnings and related calculators on this page. A nearby calculator can be useful as a cross-check when it measures the same workflow from a different input or output direction.

Formula

  • Profit = price − cost
  • Margin % = profit / price × 100

Margin and markup are not the same number. Margin measures profit against the selling price — that is what an accountant reports. Markup measures it against the cost — that is what you add when you set a price. A 50% markup is only a 33% margin.
