Harvest Hosts Membership ROI Calculator

Will a Harvest Hosts membership actually save you money?

This tool compares your current nightly campground spend against the cost of a Harvest Hosts annual membership plus what you would typically spend supporting each host you visit.

Enter your own numbers below. We do not fabricate pricing, so look up the current membership price on the official site before you calculate.

Prices change. Use the figure listed on the Harvest Hosts site today.

Hosts allow a one night stay per visit, so this is also the number of separate host visits per year.

Use the average you actually pay, not a national average. Higher rates favor the membership; cheaper state parks or boondocking shrink the gap.

Hosts ask members to make a purchase to support the location. Enter what you realistically expect to spend on wine, produce, a meal, or admission.

Calculator Methodology

Net savings = (nights × campground rate) − (membership + nights × host spend). Break even nights = membership ÷ (campground rate − host spend), when that gap is positive.

The math assumes one paid campground night avoided per host visit. It does not include fuel detours to reach a host, alcohol or food you would have bought anyway, or the value of unique experiences.

All dollar values are inputs you provide. We do not preload a membership price because it changes; always confirm the current figure on the Harvest Hosts site.
