The NBU rate calculator can help estimate your residential utility costs based on your projected electricity, water, and wastewater use. Follow the prompts and enter your usage amounts to use the rate forecaster. Having a copy of your recent NBU bill may be helpful. To start, choose the utility service type and the year you would like to calculate utility costs. When calculating electricity costs, you must designate the year and an On-Peak or Off-Peak season for an accurate estimate.
