How these numbers are made
- Property tax: Fremont County 2026 levies for tax district 2550 (Riverton), 79.925 mills in total: countywide 22.5, schools 43, BOCES 0.75, city 5, recreation 1, conservation 1, cemetery 1.675, senior citizens 2, fire 3. Each mill rate is multiplied by Wyoming's 9.5% residential assessment ratio and applied to market value.
- The calculator subtracts the 25% homeowner exemption from market value, then applies the 9.5% ratio and the levies. The starting value is the Census median market value, not an assessor figure.
- Garbage: city sanitation rate for the 90-gallon rollout, $35.63 a month; the recycling rate for that size is $36.08. Water: $26.05 minimum plus $3.29 per 1,000 gallons up to 5,999 gallons and $3.78 above. Sewer: $21.47 minimum plus $4.24 per 1,000 gallons, applied to the water use you enter.
- Electricity: Rocky Mountain Power Schedule 2 combined price from the July 2026 Price Summary (base plus riders): $24.24 a month and 11.515 cents per kWh. Gas: Black Hills customer charge $33 plus the 0.5443 $/therm total rate; the gas cost part changes. Typical use is the EIA 2020 Wyoming household average (9,180 kWh and 898 ccf a year).
- Sewer: the calculator uses the metered rate. The city lists a $50.97 Residential Flat Sewer rate but does not state who is billed flat. Electric and gas use are 2020 EIA Wyoming averages (the latest state release). The insurance figure is a 2023 statewide average. The state page does not say whether the 25% homeowner and 50% age 65+ exemptions can be combined.
