Cost per bed per month

Put the building's monthly running costs in one ledger. The result separates the cost of a full bed from the money an empty bed leaves behind, so a dormitory decision has a figure behind it.

  1. 01 Gather

    Bring the monthly ledger together

    Use the latest rent or depreciation, utilities, cleaning, maintenance, security and waste figures. Keep the sample values if you are only exploring the shape of the calculation.

  2. 02 Enter

    Tell the calculator about capacity

    Enter total beds, the beds actually occupied and any amount recovered from staff per person. The occupied count is what makes the empty-bed cost visible.

  3. 03 Print

    Take a one-page summary to the meeting

    The page stays in this browser and makes no request. Print the ledger when the figures are ready, then change the assumptions for the next option.

Questions to check

A few practical questions before you put this on the next accommodation review.

What belongs in building rent or depreciation?

Use the monthly figure you actually use to manage the building. It can be rent, or a deliberate monthly depreciation figure for a building you own; keep the basis consistent when comparing sites.

Why are empty beds shown separately?

The building still carries its monthly costs when a bed is vacant. Showing that amount makes occupancy work visible instead of hiding it inside an average.

Does recovery from staff reduce the operating cost?

The tool shows both the gross monthly cost and the recovery separately, then subtracts the recovery to show the net cost. That keeps the underlying cost easy to audit.

Can I use a different currency?

Yes. The language deck supplies the currency symbol, position, decimals and grouping convention. A later translated deck can use its local market defaults without changing the arithmetic.

Does this store our accommodation figures?

No. The calculation is rendered and recalculated in this browser only. It makes no network request and writes nothing to storage.
