Input Steps
Field by field
- 1
Choose option
Choose Calculate Margin when you know price and cost, or Set Price from Margin when you know cost and need a selling price target. Cost should include the real delivery cost of the product or service, not just the most visible direct expense.
- 2
Read outputs
Read revenue or price, cost, profit, gross margin percent, and markup percent. As a rough benchmark, retail often lives around 20-40% gross margin, services around 30-50%, and software around 60-80%, so interpretation depends on business model.
- 3
Use result
Use the result to decide whether the offer is genuinely profitable or only looks acceptable on revenue. If cost is close enough to revenue that margin lands in the teens, small discounts or scope changes can wipe out profit quickly.
- 4
Adjust for context
When using target margin mode, test the required price against what the market will actually tolerate. If the needed price is too high, fix cost structure, packaging, or scope before forcing a margin target that customers will not pay.
- 5
Re-run
Re-run after every supplier, labor, or packaging change and review by SKU or service tier each month. Track margin by channel over time because one discount-heavy channel can drag down an otherwise healthy blended average.
Run one base case and one sensitivity case before trusting a single output.
Common Scenarios
Use realistic starting points
Baseline assumptions
Revenue
100000
Cost Of Goods
$60,000
Operating Expenses
$25,000
Check gross margin first to see whether the product itself is profitable, then operating margin to see whether overhead is manageable — a healthy gross can still mean an unprofitable business if operating expenses run high.
Higher Revenue
Revenue
120000
Cost Of Goods
$60,000
Operating Expenses
$25,000
A 20% revenue increase on the same cost structure lifts gross margin percent significantly because fixed operating expenses become a smaller share. Watch whether gross margin percent crosses into a tier meaningful for your industry : a software business above 70% gross margin tells a very different investor story than one at 40%.
Lower Cost Of Goods
Revenue
100000
Cost Of Goods
$51,000
Operating Expenses
$25,000
A 15% drop in COGS flows almost entirely to gross profit when operating expenses stay fixed. Watch how much of that improvement survives to net profit : if operating expenses are still high relative to revenue, COGS gains are real but the net story is only half told.
