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.
| Split between | Each 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.
What to Leave on $45 by Service
The range runs from $6.75 to $11.25. Most people round to $50 and stop thinking about it.
| Service | Percentage | Tip | Total |
|---|---|---|---|
| Exceptional service | 25% | $11.25 | $56.25 |
| Good service | 20% | $9.00 | $54.00 |
| Standard service | 18% | $8.10 | $53.10 |
| The acceptable floor | 15% | $6.75 | $51.75 |
| Poor service | 10% | $4.50 | $49.50 |
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.
| Rounding up to | That tip is | Which is |
|---|---|---|
| Round the total to $50 | $5.00 | 11.1% |
| Round the total to $55 | $10.00 | 22.2% |
Rounding is the whole convention outside the United States — see tipping around the world.
$45 Plus Sales Tax
Every figure above is calculated on $45 before sales tax, which is the US convention. What the bill actually comes to depends on where you are — these are the totals at the rates you are most likely to meet.
| Sales tax rate | Tax | Bill with tax | 20% tip (pre-tax) | Total |
|---|---|---|---|---|
| No sales tax (OR, MT, NH, DE) | $0.00 | $45.00 | $9.00 | $54.00 |
| 6% | $2.70 | $47.70 | $9.00 | $56.70 |
| 7% | $3.15 | $48.15 | $9.00 | $57.15 |
| 8% | $3.60 | $48.60 | $9.00 | $57.60 |
| 8.875% (New York City) | $3.99 | $48.99 | $9.00 | $57.99 |
| 10.25% (Chicago area) | $4.61 | $49.61 | $9.00 | $58.61 |
Tipping post-tax instead costs $0.72 more here, and is perfectly acceptable — tax and tip explains why card terminals do it that way.
