Service Charge Allocation Calculator for UAE Buildings

Splitting a service charge budget by hand leaves rounding differences, arguments about part-year units and no clear answer when the actual spend differs from the budget. This app does the split and shows its working.

Enter your units with area, share or entitlement and months liable, then your budget lines, each with its budget, its actual year-end spend and how it is split. Every line is converted to fils and divided by weight with the largest remainder rule, so the parts add up to the budget exactly. A part-year unit has its weight reduced by months over 12 and the others pick up the rest.

What is inside:

• Budget lines and Units tabs
• Allocation: every unit against every line, with totals that match
• Fairness checks: shares add up to your expected total, units whose cost per area is far from the median
• Year-end true-up: budget share, actual share, paid on account and the balance each unit owes or is owed
• Unit statements: one A4 statement per unit
• Example building, README, CSV and JSON import and export

Which method suits which cost, how part years are handled and the shares themselves come from your building documents and the rules that apply to you. The app applies the method you choose and does not decide it. Allocation was checked against an independent integer calculation in 40 random buildings, and every line always sums to its budget.

How it differs: tenant invoicing in an accounting package bills one party at a time. This tool allocates one budget across all units, tests the split and handles the year-end balance. It issues no invoices and takes no payments.

This is a working tool, not legal, tax or financial advice, and it is not connected to or approved by any government body, regulator or bank. The app stores data in the browser on one device, so back it up with Export.
