Short-term rental ROI simulator

Calculate your electricity savings in 3 clicks

How much can you really save on electricity in your furnished rental? Our method relies on three simple variables: annual nights booked, average consumption, and price per kWh. In a few minutes, get a realistic projection and a return on investment in under 8 months.

Data-driven analysis

Why an Airbnb savings calculator is essential

Most short-term rental owners massively underestimate the energy burden of their activity. A one-bedroom rented 100 nights a year consumes on average 1,800 to 2,400 kWh, or roughly $500 to $700 of electricity that the host silently absorbs. Without a dedicated meter or rebilling system, this line item directly eats into rental profitability, often unnoticed by the operator until the annual tax filing.

Field feedback from owners equipped with a prepaid system shows a structural drop in consumption of 25 to 30%. The mechanism is behavioral: as soon as a guest sees in real time what they are consuming, they close the windows when the AC is on, turn off the heat at night, and unplug devices. This simple feedback loop turns a passive cost into a controlled one, without confrontation or negotiation with the guest.

Our calculator combines three variables: annual nights rented, average consumption per night, and the price per kWh from your provider. It then projects two scenarios: without rebilling (current situation) and with Powtiva prepayment (savings + behavioral reduction). The result is a net dollar figure per year, comparable to the cost of the kit and subscription, for a transparent ROI.

How our profitability simulator works

Three variables, one realistic projection, one annual savings figure

1

Enter your nights booked

Indicate the number of nights rented per year. For a one-bedroom in a tourist area, expect 100 to 180 nights. This data is available in your Airbnb or Booking dashboard.

2

Estimate average consumption

Typical consumption ranges between 15 and 25 kWh per night depending on the season, equipment, and property type. The calculator suggests default values based on real readings from owners.

3

Get your savings

The simulator applies your kWh price (0.25 EUR on average in 2026) and factors in the behavioral drop of 25 to 30%. Result: a net annual savings amount and a payback period in months.

Calculation method

The formula behind our electricity savings calculator

A transparent method, proven across hundreds of equipped properties

Rebilled consumption

Nights x kWh/night x kWh price = annual electric burden currently absorbed by the owner. This amount becomes recoverable as soon as a prepayment system compliant with the French law article 23-1 of law 89-462 is put in place.

Behavioral reduction

We apply a coefficient of 0.70 to 0.75 to the rebilled consumption, matching the drop observed when the guest pays for their own energy. This saving benefits the traveler and improves your carbon footprint.

Return on investment

Kit (112 to 167 EUR) + subscription (19 to 39 EUR/month depending on property type) = total annual cost. Divided by monthly savings, you get the number of months needed to pay back, generally between 5 and 8 months.

The concrete benefits calculated by our simulator

Beyond direct savings, structural gains often overlooked

Direct savings in dollars

Full rebilling of electricity to the guest eliminates this expense from your books. For a one-bedroom at 100 nights, this typically means 500 to 800 EUR recovered per year, the equivalent of one or two extra nights sold each month.

Drop in total consumption

The mirror effect of a visible meter mechanically reduces consumption by 25 to 30%. On a heavily air-conditioned property in summer, this can mean 400 to 600 kWh avoided per year, a meaningful environmental impact.

No more bad surprises

No more unexplained summer spike, no more radiator left on for three days. You cap the energy risk and turn a variable you endure into a predictable line in your business plan.

Positive marketing angle

A property with a prepaid meter attracts travelers sensitive to their carbon footprint and reassures those who fear a nasty surprise on the final bill. It signals professionalism and boosts your reviews.

Real example: a one-bedroom at 100 nights per year recovers 800 EUR

Simulation based on average French market parameters in 2026

Without a rebilling system

  • 100 nights rented yearly in an air-conditioned one-bedroom in a tourist urban area
  • Average consumption of 20 kWh per night, or 2,000 kWh yearly absorbed by the owner
  • Average kWh price at 0.25 EUR in 2026 under the regulated residential tariff

-500 EUR

Electric burden endured / year

With Powtiva prepayment

  • Electricity fully rebilled to the guest via included allowance or top-up
  • Consumption down to 14 kWh per night thanks to real-time feedback
  • Annual system cost: about 140 EUR kit amortized over 5 years + 228 EUR subscription

+800 EUR

Real net annual gain
