Thru-Hike Budget Calculator
Total cost for long-distance trail completion.
About this calculator
This calculator builds a thru-hike budget from the ground up rather than quoting a single rule-of-thumb number, because trail length and daily mileage drive everything else. It first divides your total trail miles by your average daily mileage (rounded up) to get trail days, then adds roughly one town/zero day for every five trail days — the rest-and-resupply rhythm most thru-hikers settle into. Trail food cost is trail days times your daily food budget, and town cost is town days times your town spending rate (lodging, restaurants, laundry, resupply runs). On top of gear, food, town spend, and transportation, it adds a flat 10% miscellaneous cushion on your food-and-town costs to cover gear replacement or unplanned expenses, plus a flat $50 permit fee as a rough stand-in for permit costs, which vary a lot by trail and by whether you need a permit at all.
The total is then expressed per mile, per day, and per month so you can sanity-check the number against your savings timeline. The one-in-five town-day ratio is a fixed rhythm, not something the calculator adapts to your resupply strategy: hikers who resupply from tiny trail towns with little lodging, or who mail themselves boxes and skip town stays, will spend meaningfully less than this model predicts, while hikers who take frequent zero days for injuries or morale will spend more. Gear budget is also entered as a flat number rather than itemized, so treat it as a placeholder you should refine with your own packing list.

How to Use This Calculator
- Enter total trail miles (e.g., AT ≈ 2,190, PCT ≈ 2,650, CDT ≈ 3,100) and your average daily mileage.
- Enter your gear budget ($), trail food cost per day ($), town spend per day ($), and transportation costs ($).
- Read the total budget ($), cost per mile, cost per day, and cost per month.
- Review the trail days vs. town/zero days breakdown (about 1 town day per 5 trail days) that makes up total calendar days.
- Note the total budget already includes a 10% miscellaneous allowance for unexpected gear replacement or medical costs, plus a flat permit fee.

Frequently Asked Questions
Why does the calculator assume one town day for every five trail days?
It's a rough community-average resupply rhythm, not a rule this calculator adapts to your plan: townDays is calculated as trailDays divided by 5, rounded to the nearest whole day. If you plan to mail yourself resupply boxes and stay on trail, or you're hiking a route with very short resupply gaps, your real town-day count — and the town-spend cost that comes with it — will differ from this estimate.
What's included in the flat 10% miscellaneous cost?
The calculator adds 10% of your combined trail food cost and town cost (not your gear or transport cost) as a cushion for gear replacement, medical expenses, or other unplanned spending. It's a single flat percentage rather than an itemized contingency, so a thru-hike with unusually high gear-failure risk or a planned resupply of expensive replacement gear should budget above this estimate.
Why is the permit cost a flat $50 regardless of which trail I enter?
The calculator adds a single fixed $50 permit fee to every estimate, meant as a rough average across major long trails rather than a lookup for your specific trail. Actual permit costs vary widely — some trails require no permit at all, while others (especially those crossing national parks or requiring reserved backcountry zones) can cost significantly more — so treat this line as a placeholder to verify against your trail's actual permitting system.
How is cost per month calculated, and why does it use a minimum of half a month?
Cost per month divides total cost by your total trip duration in months (total days / 30), but the calculator floors that denominator at 0.5 months so a very short trip doesn't produce an artificially inflated monthly figure from dividing by a tiny number of months. For any trip longer than about two weeks, the floor has no effect and cost per month reflects your actual pace.
