Pick a destination, group size, season, and the things you want included. The calculator returns a realistic cost range for a 7-night stay across 60 destinations, built on quarterly price audits and 12,000 active listings. No email required.
This page contains affiliate links. If you book through them we earn a commission, paid by the platform, at no cost to you. We have not adjusted our rankings for the commission rate. Full breakdown on our how-we-make-money page.
The figure the calculator returns is the 25th to 75th percentile of what a reasonable villa in that bracket actually costs, not the cheapest available listing. The cheapest listing on most platforms is a flag, not a deal. The data behind the calculator is refreshed every 90 days against Plum Guide, Onefinestay, Vrbo Luxe, HomeToGo, Le Collectionist, and direct quotes from 25 management companies.
The estimate is a band, not a point. Three inputs feed it. First, the public-platform headline rate for villas matching the bedroom and feature filters. We pull the inventory quarterly from Plum Guide, Onefinestay, Vrbo Luxe, HomeToGo, Le Collectionist, The Thinking Traveller, and Inspirato. Second, the line items that sit on top: service charge, government tax, staff gratuity norms, chef cost if selected, transport, pre-stock. Third, the destination-specific premium structure (the seven-week New Year window in St Barts, the first three weeks of August in the Mediterranean, the December-March window in Aspen).
The bottom of the band is the 25th percentile of qualifying listings, plus the average line items, minus the generic 5% discount available outside peak weeks. The top of the band is the 75th percentile plus the line items including a chef on four nights and a boat day. The band is what the trip costs, not the lowest possible figure. The cheapest listing in any destination is rarely the right answer; it is usually the property with the deposit-return complaints or the photography ten years older than the current condition.
Refresh cadence is quarterly. The current data is verified to May 2026. Major events (New Year week pricing, a F1 weekend in Monaco, the Salone in Milan) get a separate premium overlay that updates when the dates are confirmed. If a destination has thinner inventory (we have fewer than 60 active listings in our dataset), the band widens to reflect the smaller sample.
What the calculator does not do: predict an exact rate for a specific villa, surface a specific listing, or replace the contract read. It returns a budgeting figure that gets buyers within 10 to 15% of the true number for a comparable property. From there, the destination page, the best-of guide, and the affiliate-platform listings carry the rest.
The cost calculator returns a band. The budget splitter divides it across the group. The peak-vs-shoulder comparator shows what one calendar week shifts.
