Why are food days counted as nights plus one?

Because you eat on both your arrival and departure days, not just the nights you stay. A 7-night trip spans 8 days of meals, so the calculator uses nights + 1 to avoid under-budgeting food.

What is usually the biggest travel expense?

Lodging and transport (especially flights) are typically the largest items for most trips. Food and activities add up over longer stays and with more travelers, but the fixed transport and nightly lodging often dominate shorter trips.

How big a buffer should I add?

A buffer of 10–15% of the estimated total is sensible — this tool suggests 12%. It covers currency conversion, tips, baggage fees, impulse purchases, and price differences from your estimates.

Should lodging be per room or per person?

Enter it however your booking is priced — usually per room or per rental for the whole party. If you are booking multiple rooms, sum them into the per-night figure. The food input, by contrast, is per person.

How can I lower my trip budget?

Travel off-peak, stay somewhere with a kitchen to cut food costs, book flights early or use points, choose free or low-cost activities, and share lodging among more travelers to reduce the per-person nightly cost.

Source: Total = lodging × nights + food × days × travelers + transport + activities. Days = nights + 1 (arrival/departure both eat).

Note — A planning estimate. Food days are counted as nights + 1 to include both travel days. Add a buffer (10–15%) for incidentals, currency conversion, and price surprises.

Step-by-step

Lodging = 7 nights × $120.00 = $840.00.
Food = 8 days × 2 travelers × $50.00 = $800.00.
Total = lodging + food + transport $800.00 + activities $300.00 = $2,740.00 ($1,370.00/person).

How to use this calculator

Enter the number of nights and the lodging cost per night.
Enter food per person per day and the number of travelers.
Enter transport and activities as trip totals.
Read the total budget plus per-person and per-day figures, and add the buffer.

About this calculator

A realistic travel budget adds up four big buckets: where you sleep, what you eat, how you get around, and what you do. This calculator combines them — lodging billed per night, food estimated per person per day, and transport and activities as trip totals — into an overall budget, then divides it per person and per day so you can sanity-check the spend. It counts food days as nights plus one, since you typically eat on both the arrival and departure days. Lodging and transport are often the largest line items, while food and activities scale with the length of the trip and the number of travelers. Because prices, exchange rates, and impulse spending are unpredictable, the tool also suggests a buffer of around 12% on top of the estimate, so an unexpected splurge or a weak exchange rate does not blow the budget.

How it works — the formula

Lodging = Per-night × Nights
Food = Per-person-per-day × (Nights + 1) × Travelers
Total = Lodging + Food + Transport + Activities
Per person = Total ÷ Travelers

Nightly and daily costs scale with trip length and party size; transport and activities are trip-level totals.

Frequently asked

Add lodging (per night × nights), food (per person per day × days × travelers), transport, and activities. Then divide by travelers and days to check the per-person and per-day spend, and add a 10–15% buffer for surprises.
