How to budget a trip properly
Most travel budgets are a number someone said out loud in a pub. "About two grand." It is not wrong, exactly. It is just not connected to anything, so it cannot tell you whether adding two nights in Lisbon is fine or ruinous.
A budget worth having answers one question: if I change this, what happens to the total?
Price the trip in pieces, not in one number
Break it into four buckets. Nearly every trip fits:
- Getting there — flights, or fuel and tolls.
- Sleeping — per night, not per trip.
- Eating — per day, and be honest.
- Doing — entry fees, tours, the one expensive thing.
The point of the split is that each bucket responds differently to change. Adding a night moves bucket 2 and 3 but not 1. Swapping a city moves 2 and 4. A single number cannot tell you that.
Use one currency, and pick it deliberately
A total across mixed currencies is not a total. Pick the currency you are actually going to think in — usually your own — and convert as you go.
This matters more than it sounds. A place listed at "under $100" can sit well over it once converted, and the rate moves. If every number on the trip is in one currency, comparisons are real.
Cost the things you have decided, not the things you might
The common mistake is pricing every possibility. You end up with a budget for a trip nobody is taking, and it is always too high, so you stop trusting it.
Price what is confirmed. Keep possibilities visible but uncosted until they become real. The total should describe the trip you are actually taking today.
Per-night is the number that matters for accommodation
Trip totals hide the decision. "£900 on hotels" tells you nothing; "£128 a night across seven nights" tells you immediately whether you are being reasonable, and it makes the effect of adding a night obvious.
Watch for the things that break the per-night number: cleaning fees that only appear at checkout, two-night minimums, and parking. A garage space in a European city can cost more per night than the difference between neighbourhoods.
Leave a real contingency
Ten per cent is the usual advice and it is too low for a trip with flights in it. Fifteen is safer. It is not for emergencies — it is for the taxi you take because you are tired, which is a category that appears on every trip and no budget.
Re-price once, close to departure
Prices move. A budget built four months out is a guess by the time you go. One pass over the confirmed items a month before departure catches most of the drift, and it is the only re-pricing most trips need.
Doing this in heytripp
Every place and every idea on a heytripp board can carry a cost, and the trip carries a single currency so the total means something. Set a target and the board shows you where you are against it as you plan.
Ask Tripp to work out what the trip costs, or to find where the money is going, and it reads the same numbers you are looking at. Ask it to make the trip cheaper and it will tell you which choices actually move the figure — which is usually not the ones people expect.
