Air Conditioner Payback Period Calculator

Calculate how long it takes to recover your investment when upgrading to a more efficient air conditioner. Compare energy costs and find your payback period.

?
The Energy Efficiency Ratio of your existing air conditioner, typically found on the unit's label or manual. Higher EER values indicate more efficient cooling performance.
EER
?
The Energy Efficiency Ratio of the air conditioner you're considering purchasing. Modern units typically range from 10 to 15+ EER, with higher values providing better energy savings.
EER
?
The cooling power of your air conditioner measured in BTU per hour. This should match both your current and new unit for accurate comparison.
BTU/h
?
The average number of hours per day you run your air conditioner during cooling season. This directly impacts your energy consumption and potential savings.
hours
?
The number of months each year you typically use your air conditioner. Most households use AC for 3-6 months annually depending on climate.
months
?
Your cost per kilowatt-hour of electricity, found on your utility bill. This rate determines how much you pay to operate your air conditioner.
$
?
The purchase price of the new air conditioning unit before installation. This is your primary upfront investment for the upgrade.
$
?
The professional installation fee for your new air conditioner. This includes labor, materials, and any necessary electrical work.

Payback Period
The time it takes to recover your total investment through energy savings. After this period, all additional savings become pure profit on your investment.
—
Annual Energy Savings
The amount of money you'll save each year by operating the more efficient air conditioner. These savings continue for the lifetime of the unit, typically 10-15 years.
—
Current Annual Operating Cost
Your estimated yearly electricity cost with your existing air conditioner. This represents your baseline energy expense for cooling.
—
New Annual Operating Cost
Your estimated yearly electricity cost with the upgraded air conditioner. The reduction from your current cost represents your annual savings.
—
Total Upfront Investment
The combined cost of the new unit and installation. This is the total amount you need to invest upfront to achieve the projected energy savings.
