What is the difference between margin and markup?

Margin is profit as a share of the sale price (profit ÷ price) — how much of each sale you keep. Markup is profit as a share of the cost (profit ÷ cost) — how much you added on top of cost. They are never equal (except at zero): a 50% markup is only a 33.3% margin.

How do I convert markup to margin?

Select "markup" mode, enter your cost and markup %, and the calculator shows the equivalent margin. Algebraically: margin = markup ÷ (100 + markup) × 100 — so 60% markup converts to 37.5% margin.

How do I calculate sale price from cost and margin?

Use the margin mode: sale price = cost ÷ (1 − margin/100). For a $12 cost and 40% margin, the price is $12 ÷ 0.6 = $20. Enter cost, choose margin mode, and enter the margin percent to get it instantly.

How do I find markup from cost and price?

Select "price" mode, enter your cost and the sale price, and read the markup tile — it computes (price − cost) ÷ cost × 100. A $12 cost sold at $25 is a 108.33% markup with a 52% margin.

Can margin be 100 percent?

No — a 100% margin is mathematically impossible because it would require zero cost (margin = profit ÷ price, and profit can never equal price when cost is positive). The calculator rejects any margin of 100% or more and explains why.

Margin Markup Calculator

What is Margin markup calculator?

Margin Markup Calculator — Convert between margin and markup instantly: enter your cost plus a margin %, markup %, or sale price to see the full pricing picture in seconds.

This calculator ports the open-source pricing engine (lilagents/lilmargin, MIT). Margin mode: price = cost ÷ (1 − margin/100); markup mode: price = cost × (1 + markup/100); price mode reads the sale price directly. In all three directions it then reports profit, margin (profit ÷ price), and markup (profit ÷ cost). Margins of 100% or more are rejected because the math is impossible — cost would have to be zero or negative. Limitations: it models a single unit at constant cost, ignores fees and taxes, and rounds displayed results; run the numbers again after every cost change.

Good to know

Cost is assumed to be the full landed cost per unit; fold shipping, fees, and packaging into the cost field.
Margin mode rejects values of 100% or more, exactly as the upstream engine does.
When cost is zero, markup is mathematically infinite — the tool reports this as an error instead of a fake number.
Results are for a single unit at one cost level; changing volume or supplier pricing means re-running the calculation.

How it works

This calculator ports the open-source pricing engine (lilagents/lilmargin, MIT). Margin mode: price = cost ÷ (1 − margin/100); markup mode: price = cost × (1 + markup/100); price mode reads the sale price directly. In all three directions it then reports profit, margin (profit ÷ price), and markup (profit ÷ cost). Margins of 100% or more are rejected because the math is impossible — cost would have to be zero or negative. Limitations: it models a single unit at constant cost, ignores fees and taxes, and rounds displayed results; run the numbers again after every cost change.

Examples

Cost $12, want a 40% margin

Sale price $20.00, profit $8.00 per unit, markup 66.67% — same money, two reference points.

Cost $12, want a 60% markup

Sale price $19.20, profit $7.20 per unit, margin 37.50% — quoting markup as if it were margin overstates what you keep.

Cost $12, already priced at $25

Profit $13.00 per unit, margin 52.00%, markup 108.33%.
