The ownership cost calculator

Parks quote the purchase price. This shows you everything else: depreciation, compounding site fees, running costs and what letting genuinely gives back, as a total, per year, and per night you actually stay.

Estimates only, using your own assumptions. Site fees compound at your chosen rate; letting income is net of park commission but before cleaning, extra insurance and tax. This is not financial advice. Always verify against the park's own fee schedule and licence agreement.

How the maths works

Depreciation = purchase price − expected resale value.

Site fees compound: year one at your fee, each later year increased by your chosen percentage, summed over the term (fee × ((1+g)ⁿ − 1) ÷ g).

Running costs = annual figure × years (held flat so you can see the fee effect separately).

Letting income = weeks × weekly rate × years, minus the park's commission.

Total net cost = depreciation + site fees + running costs − net letting income. Cost per night divides that by the nights you'll actually stay.
