How to Use the Family Trip Budget Calculator
Family trips involve different daily spending levels for adults and kids, so using one flat per-person budget for everyone can easily over- or under-estimate your total trip cost. This calculator takes the number of adults and children, their respective daily budgets, and trip days to calculate a group-level total for each and a combined family total.
The daily budget here refers to per-person expenses like food, local transportation, and admission or activity fees. Costs like lodging are usually billed per room rather than scaling with headcount, so we recommend calculating lodging separately and adding it to the total from this calculator.
Kids' budgets are typically lower than adults', but some items — like theme park tickets or kids' activities — can cost just as much or more. Adjust the child budget realistically based on your destination and itinerary, and make sure to enter the exact number of children if you have multiple kids to minimize error in the total.
Breaking the budget down by group like this also makes it easier to compare against actual spending during the trip, and you can reuse this result as a reference point when planning your next family trip instead of estimating from scratch each time.

This calculator is based on a daily per-person budget (food, local transport, activities, etc.). Since lodging is usually billed per room rather than per person, we recommend calculating it separately and adding it to this result.
