Maximise your margins with our new gross profit calculators

At Birchall Foodservice, we know that keeping your business profitable is just as important as serving great food. That’s why we’ve created three brand-new, easy-to-use gross profit calculators to help you quickly and accurately calculate profit, set selling prices, and manage your margins with confidence.

Designed specifically for caterers, our online GP (Gross Profit) Calculators take the stress out of menu planning and give you instant answers using simple inputs. Whether you’re a chef, kitchen manager, or business owner, understanding your gross profit margin is essential—and now, it’s easier than ever.

Why Does Gross Profit Matter?

Your gross profit margin is the percentage of revenue you keep after subtracting the cost of ingredients. In a busy kitchen or catering operation, knowing your margin means you can make smarter pricing decisions, plan more accurately, and protect your bottom line.

That’s where our new calculators come in.

What Can You Do with Our Profit Margin Calculators?

We’ve created three handy tools in one place to help you:

  1. Calculate your selling price based on cost and target GP%

  2. Work out your gross profit margin based on cost and current selling price

  3. Reverse-calculate your ingredient budget based on a target margin and selling price

Each calculator is designed to be quick, intuitive, and mobile-friendly—perfect for use in the kitchen, office, or on the go.

How Do Our Calculators Work?

Using the margin formula, the calculator takes your input—whether it’s cost price, selling price, or target GP%—and does the hard work for you. There’s no need to build complicated spreadsheets or waste time with guesswork.

For example, if you know your cost is £2.00 and you want to achieve a 70% GP, simply enter those numbers and the calculator will multiply and give you the exact selling price you should charge. Or if you’re already charging £5.00, you can enter that along with your cost to see what your current gross profit margin is.

Boost Revenue Without the Headache

In today’s market, it’s more important than ever to stay on top of your figures. A small change in pricing can make a big difference to your revenue over time. Our profit margin calculators help you make those decisions with confidence and clarity.

The calculators are completely free to use, and you don’t need to download anything—just head to our website and start calculating. What’s more, you can email your calculations to yourself with the touch of a button.
