Plan your trip in the local currency and see the total in yours - with a buffer for surprises.
Daily and one-time costs plus the buffer, converted at live mid-market rates.
The trip total spread across your days - handy as an on-the-road limit.
Extra on top of the plan: the museum you didn't plan, the taxi you did not want.
Most trip budgets fail at the same spot: the hotel is in euros, the flights in dollars, and your bank account in something else entirely. This calculator keeps it simple: enter daily costs in the destination currency, one-time costs like flights in whatever currency you book them, and it converts everything into your home currency at live mid-market rates - the same open data the SumiQ app uses.
The buffer matters more than people think: on real trips, 10-20% of spending is things you did not plan. Budgeting for surprises is what keeps the budget alive after day three.
On the trip itself, this is exactly what SumiQ is for: say "lunch 240 baht" and it lands in your list, converted into your home currency automatically.
