Subtract recorded spending, unpaid commitments and any reserve from the budget that covers them. Divide what remains by the days still to fund. Check the figures before increasing the budget, and count each cost once.
A tour, a few taxis and dinner cost more than planned. Your original daily allowance now tells you less about what you can afford tomorrow.
Recalculate from the money and days you have left. You can then decide whether cheaper days will balance the trip or the plan needs a larger change.
Check three figures before changing the plan
You need the trip budget, the spending recorded so far and the number of days still to fund. Use the same currency for the budget and the spending total. Then list upcoming costs that have not yet been paid.
A daily average looks backwards. A remaining daily allowance looks forwards. One tells you what you have spent; the other helps you plan the rest of the trip.
Check what your budget includes before doing the calculation. If it excludes prepaid flights and hotels, do not subtract them again. Our guide to prepaid bookings and daily budgets explains how to separate those figures.
After four expensive days, what is left?
Suppose you start a 10-day trip with AUD 1,500. Your original allowance is AUD 150 a day. At the end of day four, you have spent AUD 850. That is AUD 250 more than the AUD 600 planned for those four days.
You have AUD 650 left for six days. Dividing AUD 650 by six gives about AUD 108.33 a day. However, you still owe AUD 180 for a hotel and want to keep AUD 110 aside for unexpected costs.
| Calculation | Amount in AUD |
|---|---|
| Trip budget | $1,500 |
| Spending through day four | −$850 |
| Remaining budget | $650 |
| Unpaid hotel balance | −$180 |
| Reserve kept aside | −$110 |
| Available for flexible spending | $360 |
| Next six days: $360 ÷ 6 | $60 a day |
The example uses hypothetical amounts. It assumes today's spending is complete and tomorrow is the first of six remaining days.
The AUD 108.33 figure includes the unpaid hotel and reserve. The AUD 60 figure leaves those amounts aside. They answer different questions, so label the allowance you choose.
Use the remaining-budget formula
Subtract a cost only once. A booking already recorded as spending must not also remain on the unpaid list.
At the end of a day, use the days from tomorrow through your final travel day. Before spending anything today, you can include today. During the day, today's remaining needs also need funding, so do not allocate every remaining dollar to tomorrow onwards.
If your trip dates change, update the day count. An extra night adds another day of costs; it does not create more money. Also check any new hotel or transport commitments.
If there are no travel days left, do not divide by zero. Review unpaid bills against the remaining money directly. If the amount available is zero or negative, there is no positive flexible allowance under the current plan.
Can cheaper days make up for an expensive day?
Yes, if the later savings cover the earlier overspend. Spending AUD 90 above plan needs AUD 90 of savings elsewhere, or extra money you can actually allocate to the trip.
You do not have to spend exactly the same amount each day. A tour day may cost more than a day spent walking and eating at local cafés. What matters is whether the remaining money covers your remaining plans.
Try a small change to the next few days: fewer taxis, a simpler meal or a lower-cost activity. Keep essential accommodation, food and transport funded. If the revised allowance cannot cover those costs, change the itinerary or reassess the total budget using money genuinely available.
Increasing a number in an app changes the plan. It does not add money to your account.
Check your entries before cutting your spending
A duplicate expense can make a budget look tighter than it is. Look for the same booking entered twice, a hotel deposit plus the full bill, or a cash withdrawal counted alongside the purchases made with it.
The ATM withdrawal guide shows how to avoid counting the same cash twice. Separately charged fees are still costs when your budget includes them.
Check currencies too. A local price and its converted home-currency value are two views of one purchase. Our guide to app totals and bank statements explains why converted amounts can differ.
For expected refunds or reimbursements, do not assume the money is available until it arrives. Keep the expectation separate from the money funding the rest of your trip.
What ExpenseTravel's daily figures mean
ExpenseTravel's “Budget per day” shows your trip budget divided by the full trip length. It is the original daily allowance. Its “Avg per day” divides all recorded spending by elapsed trip days.
The current “Safe to spend each day” card divides the remaining recorded budget by the days after today. Before the trip starts, it uses the full trip length. On the final day, it shows zero because there are no days after today.
At the end of day four in the example, it would show about AUD 108.33 for the next six days, assuming the AUD 850 spending is recorded. The app does not automatically deduct the unpaid hotel or reserve. Set those amounts aside yourself to reach the AUD 60 flexible allowance.
During the day, keep enough for today's remaining needs too. Treat the displayed figure as a budget estimate based on recorded entries, not a guarantee that all future costs are covered.

Common questions after going over budget
Should I increase my budget after one expensive day?
First calculate what remains and check upcoming costs. You may be able to balance the trip with cheaper days. Increase the budget only if you choose to allocate additional money that is actually available.
Should my remaining daily allowance include today?
It depends on when you calculate it. At the end of today, divide by the days from tomorrow onwards. Before today's spending begins, include today. During the day, allow for the costs still to come today.
Do I subtract a future hotel if I already paid for it?
Not again if its payment is included in spending so far. Subtract only an unpaid amount that still needs to come from the remaining budget.
Why is my remaining allowance lower than my original daily budget?
You may have spent faster than planned, added commitments or extended the trip. Check the spending total, costs still owed and number of days left before assuming the calculation is wrong.
