How Much Does A Gas Oven Cost To Run

by

If you want to know how much does a gas oven cost to run, the short answer is about $0.10 to $0.20 per hour. That makes gas ovens cheaper to operate than most electric models. But your exact cost depends on a few things.

This guide breaks down the real numbers. You will see how wattage, gas rates, and baking habits change your bill.

How Much Does A Gas Oven Cost To Run

Most gas ovens use between 1,000 and 2,500 BTUs per hour on a low setting. A typical bake at 350°F burns around 1,500 BTUs per hour. Natural gas prices vary by state, but the average is near $1.20 per therm (100,000 BTUs).

Do the math. 1,500 BTUs is 0.015 therms. Multiply by $1.20 and you get about $0.018 per hour. That seems very low. But ovens cycle on and off. They also have a glow bar or pilot light. Those add cost.

Real world tests show gas ovens cost $0.10 to $0.20 per hour. That range accounts for preheating, cycling, and standing pilot lights. If you bake for two hours a week, you spend maybe $0.40 to $0.80 per month.

Average Gas Oven Running Costs Per Hour

  • Low bake (300°F): $0.08 to $0.12 per hour
  • Medium bake (350°F): $0.10 to $0.15 per hour
  • High bake (450°F): $0.15 to $0.22 per hour
  • Broil setting: $0.18 to $0.25 per hour
  • Self clean cycle: $0.30 to $0.50 per cycle

These numbers assume a gas rate of $1.20 per therm. If you live in a state like California or Massachusetts, your rate may be $1.80 or more. That pushes costs up by 50 percent.

Gas Oven Vs Electric Oven Cost

An electric oven uses about 2,400 watts per hour. At $0.14 per kWh, that is $0.34 per hour. A gas oven at the same temperature costs $0.12 to $0.18. So gas is often half the price or less.

But electric ovens are more efficient at holding heat. They cycle less. Still, gas wins on price in most areas. The only exception is if you have very cheap electricity and very expensive gas.

What Factors Affect Your Gas Oven Running Cost

Your actual cost changes based on where you live and how you cook. Here are the main factors.

1. Your Local Gas Rate

Gas prices range from $0.80 per therm in Louisiana to $2.20 in Hawaii. Check your utility bill. Look for the “cost per therm” line. That number is the biggest driver of your cost.

2. Oven Age And Condition

Old ovens with standing pilot lights waste gas. The pilot burns 24 hours a day. That adds $3 to $6 per month even when you are not baking. Newer ovens use electronic ignition. They only use gas when you turn them on.

3. How Often You Preheat

Preheating takes 10 to 15 minutes. That is 15 to 25 percent of your total baking time. If you preheat for every small task, you waste money. Skip preheating for frozen pizza or casseroles that need longer cook times.

4. Oven Size And Insulation

A large oven takes more gas to heat. A poorly insulated oven loses heat. It cycles on more often. If your oven door does not seal well, you pay more every time you bake.

5. What You Cook

Long roasts at low heat use less gas per hour. But they run for hours. Quick broils use more gas per hour but for only a few minutes. The total cost depends on both time and temperature.

How To Calculate Your Own Gas Oven Cost

You can get a exact number for your home. Follow these steps.

  1. Find your gas rate on your utility bill. It is listed as price per therm.
  2. Check your oven manual for BTU input. Most are 1,000 to 2,500 BTUs per hour.
  3. Convert BTUs to therms. Divide BTUs by 100,000.
  4. Multiply therms by your gas rate. That gives cost per hour of continuous use.
  5. Add 30 percent for cycling and preheating. This gives a realistic hourly cost.

Example: 1,800 BTUs ÷ 100,000 = 0.018 therms. Multiply by $1.20 = $0.0216. Add 30 percent = $0.028 per hour. That is very low. But remember, most ovens also have a glow bar that uses electricity. That adds $0.02 to $0.04 per hour.

Tips To Lower Your Gas Oven Running Cost

  • Skip preheating for dishes that cook over 45 minutes.
  • Use the timer instead of opening the door. Each peek drops the temperature by 25°F.
  • Bake multiple items at once. Fill the oven space.
  • Turn off the oven 5 minutes early. Residual heat finishes the job.
  • Fix door seals. A cheap gasket saves $10 to $20 per year.
  • Replace old pilot lights with electronic ignition. The payback is under two years.
  • Use a toaster oven for small meals. It costs less than heating a full gas oven.

Common Questions About Gas Oven Costs

Is It Cheaper To Bake With Gas Or Electricity?

Gas is almost always cheaper. The only time electric wins is if you have solar panels or a very low off peak electric rate. For most homes, gas ovens cost 50 to 70 percent less per hour.

Does A Gas Oven Use Electricity?

Yes. The igniter, clock, and light use electricity. A glow bar igniter uses 300 to 500 watts. That adds $0.03 to $0.05 per hour to your bill. It is small but not zero.

How Much Does It Cost To Run A Gas Oven For 1 Hour?

At 350°F, expect $0.10 to $0.20 per hour. That includes gas and the small electric draw. If your gas rate is high, it could reach $0.28 per hour.

Does A Pilot Light Waste Gas?

Yes. A standing pilot burns about 500 to 1,000 BTUs per hour. That is $0.50 to $1.00 per month. It runs all day and night. Newer ovens do not have this problem.

Final Thoughts On Gas Oven Running Costs

Gas ovens are cheap to run. Most families spend under $1 per month on baking. The exact cost depends on your gas rate, oven age, and how you use it. Check your utility bill and follow the steps above. You will know your number in five minutes.

If your oven is over 15 years old, a new model may save you $20 to $40 per year. That is not a huge amount. But it adds up over a decade. For most people, the main reason to upgrade is better cooking performance, not just lower bills.
