Understand the unit first
A rate quoted per bed per day applies to one occupant for each billed day. It is different from a monthly room rental or a fixed academic-year fee. Confirm the period, room category and assignment before calculating the total.
Use the number of billed days
At RMB 25 per bed per day, 300 days gives RMB 7,500 and 365 days gives RMB 9,125. The rate is the same, but the residence period changes the total. Ask whether holidays, late arrival and departure affect the billing period rather than assuming they are excluded.
Add costs that may be separate
Bedding, deposits, utilities and personal equipment should be checked for the assigned room. Do not treat an old room photograph as proof of the current furniture or facilities. Keep any confirmed additional charges separate from the published room rate.
Keep a practical cash-flow plan
An annual total helps compare options, but payment timing determines how much money you need on arrival. Ask which charges are paid in advance, keep receipts and allow a personal spending reserve. The site calculator shows arithmetic estimates, not an invoice.
