Short-Term Mission Cost Calculator
Estimate per-person and total costs for a short-term mission trip including airfare, lodging, meals, insurance, supplies, and contingency.
About this calculator
This calculator prices out a short-term mission trip the way a team leader actually budgets one: per-person recurring costs (lodging per night and meals per day, both multiplied by the number of trip days) are added to flat per-person costs (airfare and travel insurance) to get a per-person base cost, which is then multiplied by team size to get the team's baseline cost. A flat project supplies budget (construction materials, VBS supplies, medical kits, etc.) is added on top since that cost doesn't scale per traveler, and then a contingency percentage — typically budgeted at 10-15% for short-term missions, where local price surprises and last-minute logistics are common — is applied to the running total to arrive at the full trip cost. Dividing that by team size gives the true cost per person including its share of the buffer, and dividing by trip days gives the team's daily burn rate, useful for spot-checking whether a longer or shorter trip changes the math meaningfully.
The fundraising target per person adds a further 10% on top of the true cost per person, reflecting that support letters and fundraising campaigns typically need to raise somewhat more than the bare trip cost to cover credit card fees, platform cuts, or shortfalls from a few supporters who don't follow through. Adjust the per-person inputs for your specific destination's real airfare and lodging rates before trusting the total.

Frequently Asked Questions
Why aren't airfare and insurance multiplied by trip days like lodging and meals are?
Airfare and travel insurance are flat, one-time costs per person regardless of how long the trip runs, so the calculator adds them once per person to the per-person base cost. Lodging and meals, by contrast, are recurring daily costs, so each is multiplied by tripDays before being added — a 14-day trip pays for 14 nights of lodging and 14 days of meals, but only one round-trip flight and one insurance policy per person.
Why does the contingency percentage get applied after supplies are added in?
The contingency percentage is calculated on totalWithSupplies (team cost plus the flat supplies budget), not on the team cost alone, so the buffer also covers uncertainty in the supplies line item — construction materials or VBS supplies can run over budget just as easily as travel costs can. That contingency amount is then added on top to produce the final total trip cost.
Why is the fundraising target 10% higher than the actual cost per person?
The calculator multiplies the true cost per person (which already includes the team's share of the contingency buffer) by 1.1 to set the fundraising target. That extra 10% is meant to absorb costs support-raising itself introduces — credit card processing fees, fundraising platform cuts, or a handful of pledges that don't come through — so the team doesn't fall short even if every dollar raised isn't a clean dollar of trip funding.
What does the 'cost per day' output tell me that cost per person doesn't?
Cost per day divides the full total trip cost (for the whole team, including contingency) by the number of trip days, giving the team's overall daily burn rate rather than an individual's share. It's useful for quickly checking how much shortening or lengthening the trip by a few days would move the total, since it approximates the trip's day-by-day cost sensitivity.
