Some household gadgets really can repay their purchase and installation cost, but only when your home uses enough water, electricity or heating fuel for the savings to exceed the upfront expense. The right test is simple payback: net upfront cost ÷ estimated annual savings. Net cost includes the device, installation and any required accessories, minus a rebate you have confirmed you qualify for. Annual savings should reflect your old fixture or appliance, actual use, local utility rates and maintenance.

Other inexpensive measures can be sensible waste-stoppers, yet their payback depends so heavily on the home that no universal period has been established. Use the nine options below as a way to find and price the largest recurring waste in your own household—not as a promise that every item pays back for every buyer.
How to tell whether a gadget will pay for itself
Start with a baseline. Record the old fixture’s flow rate, the bulb’s wattage and hours of use, or your heating and cooling schedule. Then estimate the annual resource reduction and multiply it by your current water, electricity or fuel rate. Subtract only a rebate that an official administrator confirms for your address and product model. The result is an estimate, not a guarantee: occupancy, weather, behavior, rates and repairs can move the payback date.
#1 Best Overall
- Surge protection: ETL-certified surge protection shields sensitive electronics and appliances from sudden power surges.
For example, a hypothetical $60 net purchase that saves $40 per year has a 1.5-year simple payback ($60 ÷ $40). If the same device saves only $15 per year in a lightly used room, payback is four years. A product can still reduce emissions and resource use even when its financial payback is slow.
Rebates are not national defaults. The U.S. Department of Energy rebate information explains that states, territories and Tribes may administer programs and set eligible products. Check the current DOE or local-utility lookup before reducing your cost; an ENERGY STAR rebate finder is a locator, not proof that you qualify.
The nine candidates, ranked by evidence strength
The table separates quantified source estimates from measures whose results depend on finding a specific source of waste. “Not stated” means the cited source does not establish a universal number.
| Gadget | What the sources establish | Main fit checks | Payback evidence |
|---|---|---|---|
| WaterSense showerhead | Average family can save more than 2,700 gallons and about $70 per year in water and electricity | Shower use, existing flow, local water and energy rates | Calculate for your price; one-year claim applies to a combined bathroom makeover |
| WaterSense faucet aerator | EPA includes aerators in a high-efficiency bathroom upgrade and says they can reduce lifetime water and electricity costs | Thread size, faucet type, desired flow and pressure | Annual savings and payback not stated universally |
| WaterSense toilet | Included in EPA’s bathroom makeover example | Rough-in, bowl size, flush performance and installation condition | Combined makeover can pay back in as little as one year |
| ENERGY STAR LED bulbs | Up to 90% less energy and 15 times longer life than standard bulbs; five frequently used replacements save about $40 annually | Socket, brightness, color, dimmer and hours used | Use your wattage, hours and electricity rate |
| ENERGY STAR smart thermostat | More than 8% lower heating and cooling bills; about $50 average annual savings, or approximately $100 in homes unoccupied much of the day | HVAC wiring, equipment compatibility, Wi-Fi and schedule | Source estimates; calculate with your actual bill |
| Water-heater insulating blanket | DOE checklist says one will pay for itself in one year or less | Tank type, insulation level, clearances and safety instructions | Older guidance; verify current suitability before installation |
| Power strip with a true off switch | ENERGY STAR says it can centralize shutoff and eliminate standby power when equipment is disconnected | Which loads can safely be switched off together | No universal savings or payback stated |
| Programmable thermostat | DOE describes savings from scheduled temperature setbacks | HVAC compatibility and a consistent occupied/unoccupied routine | No universal dollar figure stated |
| Leak-repair supplies | EPA warns household leaks can waste water | Locate leak, obtain correct washer, tape, valve or replacement part | Depends on leak rate and repair cost |
Water-saving gadgets
1. WaterSense-labeled showerhead
A WaterSense showerhead is the clearest single fixture candidate when an old head has high flow or the shower is used frequently. EPA WaterSense estimates that an average family can save more than 2,700 gallons of water and about $70 in water and electricity costs each year with a labeled showerhead. That is an average-family estimate, not a guaranteed result for a guest bathroom or a household with short, infrequent showers. Verify the label and compare the new flow rate with the old head.
Rank #2

Measure payback by adding the head, any plumber’s labor and replacement parts, then subtracting a verified rebate. Divide that net cost by your household’s estimated annual savings. Do not attach EPA’s “as little as one year” figure to the showerhead alone: that period refers to a combined main-bathroom makeover using a WaterSense toilet, showerhead and faucet aerator.
2. WaterSense faucet aerator
An aerator mixes air into the stream and can lower flow at bathroom or kitchen faucets without replacing the entire fixture. EPA’s WaterSense statistics and facts page includes faucet aerators in the high-efficiency bathroom example and notes that faucet replacements and aerators can reduce lifetime water and electricity costs. It does not provide one universal annual dollar saving for an aerator, so your calculation must use actual minutes of faucet operation, the old and new flow rates, water and sewer charges, and the energy cost of heating hot water.

A poorly matched insert can cause splashing or inadequate pressure, turning a cheap upgrade into an unused one.
3. WaterSense-labeled toilet
A labeled toilet belongs in the same bathroom-upgrade decision as the showerhead and aerator. The EPA example says a main-bathroom makeover with all three can pay for itself in as little as one year under its assumed conditions. That is a package estimate; it does not establish a one-year payback for a toilet purchased by itself.

- EASY SETUP: Start usage in minutes by plugging in the smart extension cord and connecting via the Alexa app
- CONTROL ANYTIME, ANYWHERE: Manage your electronics from afar with the power strip with USB features; schedule appliances to turn on/off automatically or remotely to fit your lifestyle

Before buying, measure the existing rough-in from the finished wall to the center of the floor bolts, confirm the bowl will fit the room, and investigate whether the flange or shutoff valve needs repair. Include removal and disposal in net cost. If the old toilet already performs well and the bathroom is lightly used, water savings may be too small for a fast payback; a failing or high-use toilet gives the upgrade a stronger case.
Lighting and control gadgets
4. ENERGY STAR-certified LED bulbs
ENERGY STAR says certified LED bulbs use up to 90% less energy and last 15 times longer than standard incandescent bulbs. It also estimates that replacing the five most frequently used fixtures or bulbs with certified lighting can save about $40 per year in energy costs. Those figures are source estimates whose results vary with wattage, hours, electricity price and bulb life.
For each lamp, calculate annual kilowatt-hours before and after: watts ÷ 1,000 × hours per day × 365. Multiply the difference by your electricity rate, then add avoided replacement purchases if you can document the old bulb’s typical life. Check lumens rather than watts for brightness, match the socket or base, and verify dimmer, enclosed-fixture, wet-location and color-temperature compatibility. Use certified products rather than assuming every LED has the same performance.
5. ENERGY STAR smart thermostat
An ENERGY STAR-certified smart thermostat can use schedules, occupancy or away controls and remote adjustments to reduce unnecessary heating and cooling. ENERGY STAR estimates more than an 8% reduction in heating and cooling bills and about $50 in average annual savings; it says homes unoccupied much of the day may save approximately $100 annually. Treat these as modeled estimates, not promises. A home with a heat pump, multi-stage equipment, radiant heat or zoning may need a compatible control or professional installation.

Identify the HVAC wiring at the thermostat and check the manufacturer’s compatibility list before purchase. Include a common-wire adapter, electrician or HVAC technician if required. Compare the expected annual saving with the net installed cost, and account for any subscription or replacement-battery expense. Do not count the same setback savings again under a separate programmable thermostat.
6. Programmable thermostat
A basic programmable thermostat can deliver schedule-based setbacks without app connectivity or cloud features. The DOE Home Energy Checklist explains that changing the set point when a building is unoccupied or asleep can reduce heating and cooling use. It does not establish a universal dollar saving for every model or climate.
This option fits households that leave and return on a predictable schedule and will actually program the device. Confirm compatibility with your HVAC voltage and equipment, then set occupied, sleeping and away periods that do not force the system to recover inefficiently. If your routine changes often, a smart thermostat’s adaptive or remote controls may be worth the additional cost; if the home is occupied continuously, either control may save little.

7. Water-heater insulating blanket
The DOE checklist identifies a water-heater blanket as a measure that “will pay for itself in one year or less.” The guidance is older and the source does not supply a publication year, so treat the statement as a screening claim rather than a current guarantee. Savings depend on tank insulation, temperature, fuel price and how much hot water the household uses.

Read the heater manufacturer’s instructions first. Do not cover controls, thermostats, pressure-relief equipment, vents or combustion openings, and do not wrap a tank that the manufacturer says should remain uncovered. Include the blanket, tape and labor in net cost; stop if the tank type or clearance makes installation unsafe. A professional can confirm suitability for gas, electric and heat-pump water heaters.
8. Switched power strip
Many electronics draw standby power while appearing off. ENERGY STAR’s low- and no-cost energy tips describe a power strip as a central shutoff: when connected equipment is genuinely disconnected, the strip can eliminate its standby draw. The source does not state a universal wattage, annual saving or payback period.

Use a strip for a group that can safely shut down together, such as a desk’s monitor, speakers and peripherals, or an entertainment system. Keep routers, medical devices, refrigeration and equipment that must record updates on continuously off the strip. For a measured estimate, use a plug-in electricity meter to record standby watts, multiply by 8,760 hours and your electricity rate, then compare that annual value with the strip’s cost.
9. Leak-repair supplies
A replacement washer, faucet cartridge, supply-line gasket, plumber’s tape or shutoff valve is not a guaranteed money-maker; it is a targeted response to a leak. EPA notes that household leaks can waste water. The financial case becomes strong when you identify continuous flow or a recurring drip and can repair it for less than the resulting water, sewer and hot-water charges.
Confirm the leak before buying parts: check the meter with all fixtures off, inspect under sinks and toilets, and look for a toilet tank that refills without use. Match the replacement part to the valve or faucet model, shut off water safely and test for leaks after reassembly. If the leak is inside a wall, at a water heater or on a main line, include professional diagnosis and possible damage prevention in your decision; a cheap part is not a substitute for safe plumbing work.
How to choose your first upgrade
- Find the largest recurring waste. A continuously running toilet, leaking faucet or heavily used incandescent bulb usually offers more measurable savings than an occasional-use gadget.
- Measure the old condition. Record flow, wattage, hours, temperature schedules, standby watts or leak volume instead of relying on a national average.
- Price the complete job. Include device, adapters, tools, delivery, disposal, installation and future consumables.
- Verify certification and fit. Look for the WaterSense or ENERGY STAR certification named in the estimate, and confirm plumbing, socket or HVAC compatibility.
- Check current incentives. Use the DOE or local utility program, read the eligibility date and model list, and obtain approval before purchase when required.
- Calculate and rank payback. Divide net cost by annual savings, then prioritize projects with acceptable payback and low safety or maintenance risk.
- Track the result. Compare utility bills over similar weather and occupancy periods; do not credit the gadget for unrelated changes in rates or behavior.
What the evidence can—and cannot—promise
EPA WaterSense estimates that an average family can save more than $380 annually by retrofitting with WaterSense-labeled fixtures and ENERGY STAR-certified appliances. That figure combines multiple upgrades and is not a promise that one gadget, or every household, will save that amount. Likewise, ENERGY STAR’s lighting and thermostat figures are estimates based on assumed use and conditions.
