When to use this calculator

  • When you need a fast estimate before making a bigger decision.
  • When you want to compare a few scenarios using the same assumptions.
  • When you need a clearer starting point before using a detailed quote or formal document.
  • When you want to sanity-check a figure you have seen elsewhere before you rely on it.
  • When you are preparing for a conversation with an adviser, supplier, or lender and want to arrive with realistic numbers.

After entering these figures, review tip, total with tip and each person pays together rather than in isolation — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.

How to read your results

Tip

Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.

Total with Tip

This is the headline outcome of the calculation, but it is most useful when read alongside the supporting metrics below it rather than in isolation. Try changing one input at a time and watching how this total moves to understand which driver has the biggest impact.

Each Person Pays

Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.

Method & assumptionsAuthoritative sources

This calculator divides a total bill among any number of people, with options for an equal split or a custom breakdown by individual. Enter the bill subtotal and choose whether to include VAT (standard UK rate is 20%) and a service charge percentage. The equal split mode divides the grand total evenly, while the custom mode lets you assign different amounts to each person based on what they ordered.

The calculator does not account for loyalty discounts, vouchers, or split-payment surcharges some venues apply. Always verify the final figure against your actual receipt. Results are for guidance only and assume a single currency (GBP).

Common mistakes

  • !Using optimistic assumptions without testing a more cautious scenario as well.
  • !Comparing outputs from different tools without checking that the inputs match.
  • !Treating the result as a final quote instead of a planning estimate.
  • !Rounding inputs too aggressively, which can produce an output that is noticeably different from your actual situation.
  • !Stopping at a single run of the tool rather than adjusting the key variable up and down to understand the range of plausible outcomes.

What to do next

  • Try at least one more scenario so you can compare a realistic range instead of a single estimate.
  • Use the related calculators below to cross-check the decision from another angle.
  • Open one of the linked guides if you need more context before you act on the result.
  • Write down the key outputs from your best two or three scenarios so you have something concrete to compare when you make the final decision.
  • If the result surprises you, change one input at a time to isolate which variable is driving the outcome before drawing conclusions.

Frequently asked

For equal splitting, divide the total including tip by the number of people. For unequal splits based on what each person ordered, calculate each person's items separately then add a proportional share of the tip.
