Splitting a $45 Bill

Two people at 20% pay $27 each; three pay $18 each. Forty-five divides evenly by three and five, so it suits a table of three unusually well.

Splitting $45.00 between two to six people
Split betweenEach pays (18%)Each pays (20%)
2 people$26.55$27.00
3 people$17.70$18.00
4 people$13.27$13.50
5 people$10.62$10.80
6 people$8.85$9.00

Always add the tip to the full bill first and divide afterwards. Splitting first and letting everyone round their own share up leaves the server short — the main calculator handles this correctly.

Working Out $45 in Your Head

Move the decimal point one place left to get 10% of $45, which is $4.50. Everything else builds from that number: double it for 20% ($9.00), add half of it for 15% ($6.75), or take 20% and subtract a tenth for 18% ($8.10).

Ten percent is $4.50. Double it to $9 for 20%, or halve it and add for $6.75 at 15%.

The same shortcut works on any bill — the full method is explained here, and the tip chart covers the amounts either side of $45.

Below 15% reads as a deliberate comment rather than a small tip, so it is worth speaking to the manager as well. The average tip percentage guide covers where these ranges came from.

Rounding the Total Up Instead

Rounding to $50 gives 11.1%, which is below the US standard. If you want 20%, $54 is the figure.

Tipping post-tax instead costs $0.72 more here, and is perfectly acceptable — tax and tip explains why card terminals do it that way.
