Is this profit margin calculator free?

Yes. It is a free, no-signup browser tool. There is no trial, no paywall, and no account.

No. Your pricing projects are stored locally in your browser using IndexedDB and localStorage. Nothing is sent to a server. Use the Backup tab to export your data as JSON.

What is the difference between markup and margin?

Markup is profit as a percentage of cost. Margin is profit as a percentage of selling price. A 50% markup on a 100 cost gives a 150 selling price — but the margin on that price is only 33.3%.

Which countries and tax systems does it support?

The calculator includes presets for South Africa VAT, United Kingdom VAT, United States sales tax, Australia GST, and an Other / custom option. The maths is region-agnostic: the tax region controls labels, default rates, and registration wording.

Does it handle landed cost on imports?

Yes. Set the supplier currency and unit cost, exchange rate, customs duty %, import tax rate, and any import-tax uplift. The analyzer converts to local currency, applies duty, and treats import tax as cost or claimable depending on registration.

Does it handle break-even?

Yes. Enter the monthly fixed-cost share this product or service must cover. The analyzer calculates break-even units, break-even revenue, expected monthly contribution, monthly surplus or shortfall, and overhead coverage.

Can I compare against competitor prices?

Yes. Enter competitor tax-inclusive prices and the analyzer shows the gap and what your margin would be if you matched them — with a warning if matching would put you at a loss.

Does it support wholesale tiers?

Yes. Build tiered pricing tables (e.g. retail / small wholesale / distributor / bulk). Margin is recalculated per tier and tiers below your minimum margin are flagged.

No. The analyzer is script-driven: pure formula functions and configurable warning rules. No AI, no API calls, no external lookups.

Does it provide tax or financial advice?

No. This is operational pricing maths only. Confirm tax, customs, and accounting treatment with a qualified professional.

Can I export and import projects?

Yes. Export a single project or all projects as JSON. Import on another device or after clearing browser data. Schema versioning is included for future migrations.

Why bother

Mistakes this tool catches

The kind of pricing errors that quietly bleed profit out of small businesses every month.

Confusing markup with margin

A 50% markup is only a 33% margin. The analyzer shows both side-by-side so you can't mistake one for the other.

Forgetting gateway and platform fees

2.9% gateway + 10% marketplace + 5% return allowance = 17.9% gone before margin. The minimum-price formula folds these in.

Pricing imports without import tax or duty

Foreign cost × FX + customs duty + import tax (cost or claimable depending on registration). Properly modelled.

Discounting below break-even

The maximum-safe-discount calculator tells you the largest discount that still hits your target margin.

Matching a competitor at a loss

Enter competitor tax-inclusive prices and see your margin if you match — with a warning when it goes negative.

Wholesale tiers below minimum margin

Tiered discount tables (retail/wholesale/distributor/bulk) flag any tier that falls below your minimum acceptable margin.

How to

Calculate true profitability in 7 steps

Same flow whether you're pricing one item, an imported lot, or a service quote.

Open the analyzer. Open the tool in any modern browser. No account, no signup. Your pricing data stays on your device.
Pick a business type. Choose general, imported product, ecommerce, manufactured, wholesale, service, or agency. Each preset loads sensible default cost lines.
Enter your costs. Add cost lines: supplier, freight, duty, packaging, labour, gateway %, marketplace %, returns. Mark per-unit, fixed, or % of selling price as appropriate.
Set tax region and registration. Choose South Africa VAT, UK VAT, US sales tax, Australia GST, or a custom tax setup. Mark whether you are registered so input tax and sales tax are treated correctly.
Drive the price. Enter a target margin, target markup, or an explicit selling price (ex or inc tax). The other fields auto-compute.
Test scenarios. What if the supplier raises prices 12%? What if you discount 15%? What if the exchange rate moves? Compare baseline vs scenario in real time.
Print the report. Use the Report tab to print a professional A4 PDF with cost breakdown, landed cost, competitors, tiers, break-even, warnings and disclaimer.

When you need more than a browser pricing analyzer

This free tool covers single-product or single-service pricing on one device. When you need multi-user pricing approvals, an audit trail, integrations with billing/inventory, and recurring price updates, you need a custom platform.
