The bill arrives. It says 850 pesos. There are four of you. Someone adds a tip. Now everyone wants to know what they owe — in dollars, because that is how they budget. The mental math at the table is awkward, and splitting it wrong means someone pays too much or too little.
Here is how to do it correctly, with a worked example.
The worked example
A restaurant dinner for four. The bill comes to 850 MXN. You decide to add a 15% tip.
- Tip amount: 850 × 0.15 = 127.50 MXN
- Total with tip: 850 + 127.50 = 977.50 MXN
- Per person (4 people): 977.50 ÷ 4 = 244.38 MXN
At an exchange rate of 17.20 MXN/USD:
- Per person in USD: 244.38 ÷ 17.20 = $14.21
So each person owes 244.38 pesos, or about $14.21 in dollar terms. That is the clean number to share with the table.
How the numbers change with different tip percentages
| Tip % | Total (MXN) | Per person (MXN) | Per person (USD) |
|---|---|---|---|
| No tip | 850 MXN | 212.50 MXN | ~$12.35 |
| 10% | 935 MXN | 233.75 MXN | ~$13.59 |
| 12% | 952 MXN | 238 MXN | ~$13.84 |
| 15% | 977.50 MXN | 244.38 MXN | ~$14.21 |
| 18% | 1,003 MXN | 250.75 MXN | ~$14.58 |
| 20% | 1,020 MXN | 255 MXN | ~$14.83 |
850 MXN bill, 4 people, rate approximately 17.20 MXN/USD.
Where it gets complicated
The math itself is not difficult. The problem is doing it at a table, on the spot, in a currency that is not yours, with people pulling out phones and getting different answers because they used different rates.
A few things make it messier:
- Unequal splits: if some people ordered more or had drinks and others did not, splitting by item rather than equally changes the numbers.
- Service charge already on the bill: some restaurants include a propina. Tip on top of a tip means you overpay. Check the bill first.
- Rounding confusion: 244.38 pesos is awkward. Rounding up to 250 per person is common and adds a small extra tip.
The simplest approach at the table
- Check the bill for an included service charge before deciding on a tip amount.
- Agree on the tip percentage with the table.
- Calculate the total with tip.
- Divide by the number of people.
- Convert to dollars if needed so everyone understands what they owe.
The Tip & Split tool in Pesos to Dollars does all of this in one screen: enter the bill in pesos, choose the tip, set the number of people, and it shows each person's share in both MXN and USD. You can try it once before upgrading.
