Formula Used
1. Gross Before Tax
Gross Before Tax = Base Utility Bill + Common Area Charge + Service Fee + Late Fee - Discount
2. Tax Amount
Tax Amount = Gross Before Tax × (Tax Rate ÷ 100)
3. Grand Total
Grand Total = Gross Before Tax + Tax Amount
4. Fixed Share Pool
Fixed Share Pool = Grand Total - Metered Charge Portion
5. Room Fixed Share
Room Fixed Share = Fixed Share Pool × (Room Weight ÷ Total Weight)
6. Room Meter Share
Room Meter Share = Metered Charge Portion × (Room Meter Units ÷ Total Meter Units)
7. Final Room Share
Final Room Share = Room Fixed Share + Room Meter Share, adjusted for any minimum occupied room charge.
Weights can be based on equal sharing, guest count, nights stayed, occupied days, or a custom value set by management.

Frequently Asked Questions
1. What is the best split method for serviced accommodation?
Use guest count or occupied days when consumption rises with usage. Use equal sharing when rooms are similar and occupancy patterns rarely vary.
2. Should vacant rooms share utility costs?
That depends on policy. Some operators assign a partial share to vacant rooms because common lighting, security, and standby systems still create overhead.
3. When should I use the metered charge portion field?
Use it when part of the bill comes from measured room usage, such as electricity or water meters. The remaining pool is split by weights.
4. Can I apply discounts before tax?
Yes. This calculator subtracts the discount before calculating tax, which matches many billing workflows and keeps final room shares consistent.
5. Why use a minimum occupied room charge?
It prevents very small bills for lightly used rooms. This can be useful when every occupied room should contribute a baseline amount.
6. What happens if my minimum charge is too high?
The calculator reduces the effective minimum automatically when needed. That keeps the full split balanced without creating extra charges beyond the total bill.
7. Can I use custom weights for premium suites?
Yes. Choose the custom method and enter a higher weight for premium rooms, larger units, or rooms with higher expected consumption.
8. What should I export after calculation?
Export CSV for spreadsheets and reconciliation. Export PDF for management reviews, guest accounting records, or front desk approval workflows.
