Splitting a $30 Bill
Two people at 20% pay $18 each. Three people pay $12 each, which is why $30 is such a comfortable number for a group lunch.
| Split between | Each pays (18%) | Each pays (20%) |
|---|---|---|
| 2 people | $17.70 | $18.00 |
| 3 people | $11.80 | $12.00 |
| 4 people | $8.85 | $9.00 |
| 5 people | $7.08 | $7.20 |
| 6 people | $5.90 | $6.00 |
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 $30 in Your Head
Move the decimal point one place left to get 10% of $30, which is $3.00. Everything else builds from that number: double it for 20% ($6.00), add half of it for 15% ($4.50), or take 20% and subtract a tenth for 18% ($5.40).
Ten percent is $3. Double it for $6 at 20%, or add half for $4.50 at 15%. Most people round the 18% figure of $5.40 up to $6 and move on.
The same shortcut works on any bill — the full method is explained here, and the tip chart covers the amounts either side of $30.
What to Leave on $30 by Service
The whole normal range on $30 is $4.50 to $7.50, so this is a bill where rounding beats calculating.
| Service | Percentage | Tip | Total |
|---|---|---|---|
| Exceptional service | 25% | $7.50 | $37.50 |
| Good service | 20% | $6.00 | $36.00 |
| Standard service | 18% | $5.40 | $35.40 |
| The acceptable floor | 15% | $4.50 | $34.50 |
| Poor service | 10% | $3.00 | $33.00 |
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 $30 to $36 is exactly 20%, which is the tidiest coincidence on this list.
| Rounding up to | That tip is | Which is |
|---|---|---|
| Round the total to $33 | $3.00 | 10.0% |
| Round the total to $34 | $4.00 | 13.3% |
| Round the total to $35 | $5.00 | 16.7% |
| Round the total to $36 | $6.00 | 20.0% |
| Round the total to $37 | $7.00 | 23.3% |

$30 Plus Sales Tax
Every figure above is calculated on $30 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 | $30.00 | $6.00 | $36.00 |
| 6% | $1.80 | $31.80 | $6.00 | $37.80 |
| 7% | $2.10 | $32.10 | $6.00 | $38.10 |
| 8% | $2.40 | $32.40 | $6.00 | $38.40 |
| 8.875% (New York City) | $2.66 | $32.66 | $6.00 | $38.66 |
| 10.25% (Chicago area) | $3.08 | $33.08 | $6.00 | $39.08 |
Tipping post-tax instead costs $0.48 more here, and is perfectly acceptable — tax and tip explains why card terminals do it that way.
