How it's worked out
The calculator only adds and multiplies the numbers you type. It has no prices, averages or exchange rates of its own, so it can't be out of date, and it can't tell you what Lisbon costs: you bring the numbers, it does the sums.
| Getting there | fare per person × travelers + fuel + tolls and parking |
|---|---|
| Fuel (miles) | distance ÷ miles per gallon × price per gallon |
| Fuel (kilometres) | distance × litres per 100 km ÷ 100 × price per litre |
| Lodging | price per room per night × rooms × nights |
| Food and drink | per person per day × travelers × days |
| Getting around | per person per day × travelers × days |
| Activities | per person × travelers |
| Buffer | everything above × buffer % |
| Total | everything above + buffer |
| Per person, per day | total ÷ travelers ÷ days |
| To save each month | total ÷ whole months left until the month you leave (at least 1) |
- Days start as nights + 1, because you eat and get around on the day you arrive and the day you leave. Change it if your trip is different.
- The 10% buffer is our starting point, not a statistic. Raise it for a long trip or a place you don't know; set it to 0 to see the bare sum.
- Currency is a label. Type every amount in one currency; nothing is converted.
- Rounding: each line is shown to the nearest whole unit, and the total is rounded once, from the exact sum.
- Sharing: "Copy link" writes your numbers into the address, after the #, so whoever opens the link sees the same budget. There's no account and nothing to save.
Where to find real numbers
For flights and hotels, use the price you're quoted for your dates. For the rest, these public sources publish current figures:
- U.S. EIA: Gasoline and Diesel Fuel Update: this week's average US fuel prices, by region.
- fueleconomy.gov: Find and Compare Cars: the official miles per gallon of your car.
- U.S. GSA: Per diem rates: what US government travellers are allowed for a hotel night and a day's meals in each US city. It's an allowance, not a quote, but it's a published number to start from.
- U.S. Department of State: Foreign per diem rates: the same allowance for cities abroad.
Use it however you like
The formulas above work in any spreadsheet, and the CSV opens in one. Quote the results, screenshot them, or send a link to a budget you've filled in: a guide to a week in Lisbon can link straight to its own numbers. No credit needed.
