Frequently asked questions
01Margin vs markup?
Margin = profit / revenue. Markup = profit / cost. A 100% markup is only a 50% margin — don't confuse them when pricing.
02What's a healthy margin?
Ecommerce: 20–40% gross is healthy. SaaS: 70%+. Professional services: 30–50%.
03Does it handle Shopify fees?
Add them to the cost field for now. A dedicated Shopify Profit Calculator launches in Phase 3.
04To hit margin Y% at price X, what's my max cost?
Max cost = price × (1 − margin/100). Selling at $50 and targeting 40% gross margin → max cost is $30. This 'reverse pricing' lets you set a buy-cost ceiling before negotiating with suppliers.
05Gross vs net margin?
Gross margin subtracts only direct product cost (COGS) from revenue. Net margin also subtracts operating expenses, marketing, taxes, and salaries — always lower than gross. This tool computes gross; net requires a full P&L.
06Should I include sales tax / VAT in the calculation?
Compute margin on pre-tax revenue. If your displayed price is tax-inclusive (common in EU), subtract VAT first. Make sure revenue and cost are both on the same basis — either both tax-inclusive or both pre-tax.
