Oil usage estimator

Heating oil use tracks outdoor temperature with surprising precision — dealers have scheduled deliveries by degree-day math for half a century. This tool brings the same arithmetic to your tank: enter your home's profile and a forecast, get gallons per day and days remaining.

Degree-day fuel estimate

Gallons currently in the tank Average outdoor temp this week (°F) K-factor, if you know it

Launching with the heating season: gallons/day from your K-factor or home profile, plus a days-remaining estimate that matches how dealers actually schedule deliveries.

The idea in one paragraph

A degree-day is how far the day's average temperature sits below 65°F: a 35°F day is 30 degree-days. Your home burns a roughly fixed number of degree-days per gallon — the K-factor printed on many delivery tickets. Divide the forecast's degree-days by your K-factor and you have gallons. Until the calculator ships, your last delivery ticket plus the tank chart gets you most of the way.
