How to interpret the result

The output shows the selling price you would need to charge to keep your gross margin percentage exactly where it was before your supplier cost went up. If you leave your price unchanged after a cost increase, your margin percentage falls even though your turnover looks the same — the calculator simply reverses that arithmetic to show what price restores the original ratio.

It is worth reading the result alongside how you actually sell. A like-for-like price change on a single line item is straightforward to apply; a change that ripples across a whole catalogue, a tiered price list, or contracts with fixed pricing clauses is not. Treat the figure as the target for that one product or service, not as a blanket instruction to apply the same percentage everywhere.

Limitations and good practice

The calculator only holds gross margin percentage constant — it does not account for how customers might respond to a higher price, what a competitor is charging, or whether demand for the product is sensitive to price at all. A mathematically correct price rise that customers simply refuse to pay does not protect your margin in practice; it just moves the volume risk to a different part of the business.

Before rolling a rise out, it is good practice to sense-check it against a small sample of customers or a single order, review any pricing clauses in existing contracts, and consider whether part of the cost increase could be absorbed through efficiency rather than passed on in full, as the page's FAQ already notes. Use the result as a starting reference point for that conversation, not as a final decision — as with all figures on this page, it is an illustration rather than a funding quote or credit decision.
