Small Thermostat Changes Add Up to Big Savings
Adjusting your thermostat by just a few degrees can meaningfully reduce your heating bills over the course of a season. This calculator shows you exactly how much you can save based on your heating type, current bill, and how many degrees you plan to lower the setting. Use the results to plan a smarter heating strategy for your home.
Lowering your thermostat by 3–5°F can save 6–10% on your monthly heating bill. Over a 5-month heating season, that adds up to $45–$90 on a $150/month bill. Gas heating shows the highest savings per degree, while electric heating is more efficient but less responsive to temperature changes. Programming your thermostat to lower temperatures at night and while away is the most effective habit for consistent savings.
