Wisconsin heating oil and propane prices per gallon this week

Every propane winter on file

Last winter Wisconsin propane averaged $1.943, with a high week of $2.069 on March 23, 2026. Across the seasons since 2013-14, the November to March average ended above the mid-October price in 12 of 13 winters. The record week is $4.490, on January 27, 2014.

What a fill costs

A 500-gallon tank filled from 30 % to the 80 % level commonly used for propane takes 250 gallons, $485 at this week's Wisconsin average. A 1,000-gallon tank from 20 % takes 600 gallons, $1,164. The EIA's wholesale propane price for Wisconsin is $1.256, so $0.684 of each gallon goes to delivery, storage and the dealer. The propane tank calculator takes your own tank, gauge and any delivery fee.

Wisconsin against its neighbors

This week Wisconsin propane is $0.074 cheaper than in Minnesota, $0.494 cheaper than in Michigan and $0.003 cheaper than in Illinois. Wisconsin heating oil, at $5.786, is $0.022 cheaper than Michigan's.

The winter month by month

NOAA's normals give Wisconsin 1,313 heating degree days in December, 1,456 in January and 1,199 in February. By the same scaling as the season estimate, the average propane home burns about 194 gallons in January alone. The winter budget spreads the season month by month, and the LIHEAP page gives the federal income ceiling for heating help, $64,395 a year for three people in Wisconsin.

Planning the season

Propane tanks are usually filled to about 80 %, so a 500-gallon tank holds some 400 gallons at the start of the season. Against the 781 gallons the average Wisconsin propane home burns from November to March, that is about 2 tanks over the winter, before cooking, hot water and the shoulder months. A household on automatic delivery leaves the timing to the dealer; one that calls for its own deliveries should watch the gauge from December, when the colder months begin. The days-left calculator turns a gauge reading into a date, using Wisconsin's monthly normals.
