A gap night is an empty night between stays that is hard to sell cleanly.

Why ask for total nights and booked nights?

Those are usually easier to know accurately than a guessed occupancy number, and they make the calendar math more reliable.

No. It is a planning model that shows how cleaner calendar use could affect revenue.

What this means

Gap-night efficiency looks loose

Gap-night efficiency is below the planning range used here

You entered 22 booked nights inside 30 available nights, with about 5 gap nights worth about $1,050 at the current nightly rate. That puts gap-night efficiency at about 81.5%.

If average stay length rises from 2.6 to 3.4 nights, the reservation count would fall from about 8.5 to about 6.5 in the same booked-night base. That could potentially recover about 1.2 gap nights and about $247 in revenue if those gap nights are really being created by turnover pattern rather than weak demand.

Planning ranges used in this gap-night efficiency calculator

This calculator uses a planning guide because gap nights and stay length depend on your listing, market, and minimum-stay rules.

The guide is there to show whether your gap-night pattern is reasonably clean, not to score the whole calendar or compare you with a whole city.

How to use this stay length calculator

This calculator turns total nights, booked nights, and gap nights into a gap-night efficiency view, then shows what longer stays could potentially recover.

Why stay length matters

Longer stays do not just reduce turnover work. They can also clean up the calendar by shrinking the number of empty nights stuck between reservations.

That makes stay length a profit lever, not just a convenience lever.

How to use the output

Look first at the gap-night revenue loss, then at the potential revenue recovered at the longer stay target.

Treat that recovery number as directional. It is strongest when the empty nights are being created by short-stay turnover, not by weak demand.
