Build a travel budget you can recalculate
Separate shared and per-person costs, attach real quotes when you have them and keep an allowance visible. A worked example shows how one changed choice affects the total.
A useful travel budget is a calculation you can update. One daily figure hides how many people are travelling, how many nights they need and which activities are included. Keep those inputs visible so a change of plan does not require starting again.
Separate shared and individual costs
A room may be priced for the whole group while attraction admission is charged per person. Mark the basis of each line. Use the total quoted for your actual dates, occupancy and conditions, rather than mixing a room-only rate with a fully inclusive quote.
Keep travel to the destination separate from local spending. Include the number of days and nights, which need not be the same. A late arrival and early departure can produce three hotel nights but fewer full sightseeing days.
Follow a worked example
These figures are invented only to demonstrate the calculation. They are not current prices for Lisbon, Porto or any named business. The example covers two people, three nights and three full days, excluding travel to and from the destination.
| Cost | Example calculation | Group total |
|---|---|---|
| Shared accommodation | €110 × 3 nights | €330 |
| Meals | €28 × 2 people × 3 days | €168 |
| Local transport | €18 × 2 people | €36 |
| Activities | €40 × 2 people | €80 |
| Subtotal | Sum of the four lines | €614 |
| Chosen planning allowance | Rounded example allowance | €62 |
| Example total | €614 + €62 | €676 |
The example total is €338 per person. Replace every input with your own information before relying on the result. An allowance is a planning choice, not a guarantee that unexpected costs will stay within it.
Change one decision at a time
Adding €20 per night to the shared room adds €60 across three nights. Adding €10 to each person’s food budget per day also adds €60 across three days. The same numerical change can therefore buy two different kinds of convenience.
Discuss which choice you value. If the accommodation location changes the transport plan, update that line too instead of treating the room decision as isolated.
Keep evidence with the numbers
For a real quote, save its direct link, date checked, currency, full total and cancellation conditions. Replace estimates with confirmed amounts when you book. Keep later actual spending in a separate column so you can compare like with like.
Attach the budget to a route such as the three-day Lisbon plan. For meals, use the menu-comparison sheet to turn a headline menu price into a complete intended order.
Method note
This worksheet is original editorial planning guidance. Every price in the example is hypothetical; the arithmetic is intended to be reusable with your own inputs.
