Recipe costing

What should one serving cost?

  • Start with the whole batch, including your time.

Ingredients alone do not tell you the full cost.

01 · Include usable yield

Cost the ingredients you actually use.

  • Flour $1.00 + butter $1.60
  • Strawberries: $5 / 500 g
  • 80% usable yield · use 200 g

Ingredients: $5.10

Strawberry cost: $5 × 200 ÷ (500 × 0.80) = $2.50.

02 · Add time and overhead

Count the full batch cost.

  • Ingredients $5.10
  • Labor $16.00
  • Allocated overhead $2.90

Batch cost: $24.00

These sample costs include labor and allocated overhead.

03 · Divide by portions

Eight servings. One clear cost.

  • Batch cost ÷ servings
  • $24.00 ÷ 8

$3.00 per serving

Use the number of portions you can actually sell.

04 · Set an explicit target

For a 40% margin on entered costs…

  • Price = cost ÷ (1 − margin)
  • $3.00 ÷ (1 − 0.40)

Price: $5.00

Fees, tax and unallocated overhead are excluded here.

Campaign profitability

Is a 3× ROAS profitable?

  • The answer depends on what you keep before ad spend.

ROAS compares attributed revenue with ad spend.

01 · Define your margin

Keep 40 cents from each dollar.

  • Net revenue less variable costs
  • Include product, fees and fulfillment.
  • Exclude advertising from this margin.

Contribution margin: 40%

Use contribution margin before advertising, not net margin.

02 · Find the threshold

Break-even ROAS starts with margin.

  • Break-even ROAS = 1 ÷ margin
  • 1 ÷ 0.40

Break-even: 2.5×

At 40% contribution margin, each $1 of ads needs $2.50 in revenue.

03 · Test one campaign

$1,000 in ads. $3,000 revenue.

  • Observed ROAS = 3×
  • $3,000 × 40% = $1,200
  • $1,200 − $1,000 ad spend

$200 after ads

That is contribution after ads, before fixed overhead and tax.

04 · Check the assumption

At a 25% margin, 3× loses money.

  • $3,000 × 25% = $750
  • $750 − $1,000 = −$250
  • New break-even ROAS = 4×

Same ROAS. Lower margin.

Match revenue, costs and attribution to the same period.

Pricing decisions

20% off can cut contribution in half.

  • Follow one item from its original price to the discount.

This example excludes fees, fixed overhead and tax.

01 · Start with the unit

Price: $50. Unit cost: $30.

  • $50 − $30 = $20 contribution
  • $20 ÷ $50 = 40% margin

$20 per item

Contribution here means price less the stated unit cost.

02 · Apply the discount

A 20% discount means $10 off.

  • $50 × (1 − 20%) = $40
  • The unit cost stays at $30.

New price: $40

The customer pays 20% less. Your cost has not changed.

03 · Recalculate contribution

$40 − $30 leaves $10.

  • Contribution falls from $20 to $10.
  • New margin: $10 ÷ $40 = 25%.

50% less contribution

A price discount and a contribution decrease use different bases.

04 · Test the sales target

You need twice as many units.

  • 100 units × $20 = $2,000
  • 200 units × $10 = $2,000
  • Assumes unchanged unit economics.

Demand is not guaranteed.

Check capacity, fees and extra costs before relying on more sales.

Keep the assumptions with the answer.

All figures are hypothetical. Each example uses the stated costs, margin and period; it does not predict demand or campaign results. The calculators and worksheets let you change those assumptions.
