Split a master utility bill across your units
Drop in your unit list and Ratiotally splits the water, sewer, trash or gas bill by square feet, occupants or bedrooms, keeps the common-area and vacant shares with the owner and makes it add up to the cent — in your browser; nothing is uploaded.
How it works
- List the units — unit, square feet, occupants, bedrooms and days occupied — in the template, or try the sample.
- Enter the master bills, the common-area deduction and your lease's method mix.
- Print the split with every unit's charge, or export the charge lines to post in your rent software.
Why Ratiotally
For small landlords with a master-metered building: one water, sewer, trash or gas bill and several units. RUBS (ratio utility billing) splits that bill by a formula your lease names. Ratiotally does the formula, the vacancies and the rounding every month, from a unit list you keep in a spreadsheet.
Your unit list
One row per unit: square feet, occupants, bedrooms and, for a move-in or move-out, the days it was let.
Any blend
Square feet, occupants, bedrooms and equal per unit in any mix, like 50% square feet and 50% occupants.
Vacancies and common areas
The owner keeps the common-area share and the vacant days; part-month units pay only for their days.
Exact to the cent
Every bill is split in whole cents with largest-remainder rounding, so the charges plus the owner's share equal the bill.
Common-area what-if
What tenants and the owner pay at a 0% to 25% common-area deduction, and the highest unit charge.
Flags and Texas checks
Missing square feet or occupants, duplicate units, days past the period, and optional checks against the Texas water rules.

FAQ
Is my data uploaded?
No. Your files are read by JavaScript in your browser tab and never sent to us or anyone else. Unit rows aren't stored, so closing the tab clears them. Settings can be saved in this browser if you ask.
What is RUBS?
RUBS (ratio utility billing system) splits a master-metered utility bill among units by a formula instead of a meter in each unit — usually square footage, occupants, bedrooms or a blend. The lease has to allow it and name the method.
How does Ratiotally split a bill?
It takes off the common-area deduction (the owner's), splits the rest across your method mix, and splits each method's slice by each unit's square feet, occupants, bedrooms or an equal share, scaled by the days the unit was let. Every amount is in whole cents and the leftover cents go to the largest remainders, so nothing is lost or invented.
Who pays for vacant units?
By default the owner: a vacant or part-month unit's square-foot, bedroom and per-unit share for its empty days stays with the owner. Occupant shares always go to the people who lived there. You can switch to spreading the vacant share over occupied units if your lease says so.
Does it follow the Texas rules?
Optionally. Turn on Texas checks to use the ratio occupancy and bedroom scales in 16 TAC §24.281 and get flags if the square-foot share is over 50%, the common-area deduction is under 5%, or the building has fewer than five units. It doesn't register you with the PUC or write your lease disclosures.
What's free?
Importing any number of units, every bill split exactly, the owner's share, every flag, 3 common-area what-ifs and 12 units on screen and in print (with a footer). Pro shows everything and adds the Excel workbook and CSV exports.
Is this legal advice?
No. Ratiotally applies the arithmetic it describes to the figures you provide. Billing tenants for utilities needs a lease that allows it, and states and cities set their own disclosure, method and fee rules. It is not affiliated with any utility or agency.
