RUBS Billing

Ratio utility billing, or RUBS, proportionally allocates costs for water, gas, electric, trash, cable and other services to residents based on an industry-accepted formula that takes into account unit size, layout, occupancy and more.

RUBS billing is typically utilized where space, system age, configuration or complexity makes it impossible or too expensive to install individual submeters. It is a fast and inexpensive solution that improves utility cost recovery, allocates costs more fairly among tenants, decreases unnecessary consumption, and increases NOI across your portfolio. RUBS is suitable for all types of multifamily properties, including apartments, condominiums, HOAs, mobile home parks and more.

Custom Rubs Formulas

While all of our RUBS billing is done according to industry-accepted practices, we know that every situation is not identical. That’s why we work with property owners and managers to create ratio utility billing formulas that fit the precise nature of their property and situation. The result: Higher recovery rates and happier residents.


Our commitment to providing unparalleled service, highly effective utility system design and maximum cost recovery has helped us recover over 90% of utility costs for our clients.

What Is RUBS?

A ratio utility billing system, or RUBS, is an alternative to a true utility submetering system. With submetering, each unit’s consumption of water, gas or electricity is measured by a physical device. With RUBS, utility costs are allocated using an industry-accepted formula, typically taking into account the number of occupants per unit, unit square footage and layout, the number of bedrooms and bathrooms, specific amenities and other factors. The result is a fair and equitable division of master utility bills, which leads to improved cost recovery, increased net operating income and increased revenue.

When Is RUBS Billing Used?

RUBS is typically used when a building’s infrastructure is too old or complicated for submeters to be installed, or when a property owner or manager requires a less costly alternative to true submetering. Because there is no equipment to buy, install and maintain, RUBS is less expensive than a water, gas or electric submetering system. The flip side, though, is that RUBS is less precise than submetering. It does not measure a unit’s exact utility consumption; rather, it allocates cost based on a mathematical formula.
