How to Save Money on Utilities: 12 Simple Changes That Lower Your Bills Every Month

Utility bills are one of those expenses that most people accept as fixed — you use electricity, water, and gas, and you pay whatever the bill says. I used to think the same way until I actually looked at my bills closely and realized I was paying far more than necessary for energy I was wasting.

Thankfully, I was able to save money on utilities after making a few strategic changes — some that took less than five minutes — I cut my monthly utility costs by over $80. That’s nearly $1,000 a year in savings from adjustments I barely notice. If you want to save money on utilities without sitting in the dark or taking cold showers, this guide is for you.

Here are 12 simple changes that can meaningfully reduce your electricity, water, gas, and internet bills starting this month.

How Much Do Utilities Actually Cost?

Before cutting costs, it helps to know what you’re working with. According to the U.S. Bureau of Labor Statistics, the average American household spends approximately $400-$500 per month on utilities, including electricity, gas, water, internet, and phone. That’s $4,800 to $6,000 per year — one of the largest recurring expenses after housing and transportation.

The breakdown typically looks like this:

• Electricity: $120-$180/month (varies significantly by region and season)
• Natural gas: $50-$80/month
• Water and sewer: $40-$70/month
• Internet: $60-$80/month
• Phone: $50-$80/month

Even a 15-20% reduction across these categories adds up to serious annual savings. Let’s go through each area.

Electricity: Where the Biggest Savings Are

1. Adjust Your Thermostat Strategically

Heating and cooling account for roughly 50% of the average home’s energy bill, making your thermostat the single biggest lever you have to save money on utilities.

The Department of Energy recommends setting your thermostat to 68°F in winter and 78°F in summer when you’re home. For every degree you adjust beyond these benchmarks for an 8-hour period, you can save approximately 1% on your heating and cooling bill.

If you don’t have a programmable thermostat, consider getting one. A basic programmable thermostat costs $20-$50 and can save you $100+ annually by automatically reducing heating and cooling when you’re sleeping or away from home. Smart thermostats like the Nest or Ecobee can learn your habits and optimize automatically.

2. Switch to LED Bulbs Everywhere

If you’re still using incandescent or CFL bulbs anywhere in your home, you’re paying too much for lighting. LED bulbs use approximately 75% less energy than incandescent bulbs and last 15-25 times longer.

Replacing just 10 incandescent bulbs with LEDs can save you $50-$100 per year on electricity. LED bulbs now cost as little as $1-$2 each, making this one of the highest-return investments in energy savings.

3. Unplug the Energy Vampires

Electronics that are plugged in but turned off still draw power — this is called phantom load or standby power. According to the Department of Energy, phantom loads can account for 5-10% of your total electricity bill.

The biggest offenders include game consoles, cable boxes, phone chargers, coffee makers, and older TVs. You can eliminate phantom loads by unplugging devices when not in use, using smart power strips that cut power automatically, or putting entertainment centers on a single power strip you switch off at night.

I started unplugging my TV setup and kitchen appliances when not in use, and my electricity bill dropped noticeably within the first billing cycle.

4. Run Appliances During Off-Peak Hours

Many utility companies charge different rates depending on the time of day. Electricity is typically cheaper during off-peak hours — usually late evening, overnight, and early morning. Running your dishwasher, washing machine, and dryer during these windows can save money on utilities without changing how much you use.

Check with your utility provider to see if you’re on a time-of-use rate plan. If not, ask about switching — it could save you 10-20% on electricity if you can shift heavy usage to off-peak times.

5. Maintain Your HVAC System

A dirty air filter forces your heating and cooling system to work harder, using more energy and driving up your bill. Replace your HVAC filter every 1-3 months — a $5-$15 filter can prevent hundreds in wasted energy costs.

Additionally, schedule annual maintenance for your HVAC system. A well-maintained system runs 15-20% more efficiently than a neglected one. Many utility companies offer free or discounted energy audits that can identify specific inefficiencies in your home.

Water: Small Changes, Steady Savings

6. Fix Leaks Immediately

A single dripping faucet can waste over 3,000 gallons of water per year. A running toilet can waste up to 200 gallons per day. These leaks add up on your water bill far more than most people realize.

Check all faucets, showerheads, and toilets for leaks monthly. Most faucet leaks can be fixed with a $2 washer replacement. For toilets, drop food coloring into the tank — if color appears in the bowl without flushing, you have a leak that needs fixing.

7. Use Water-Efficient Fixtures

Low-flow showerheads and faucet aerators reduce water usage by 25-50% without a noticeable difference in water pressure. A low-flow showerhead costs $10-$30 and pays for itself within a month or two.

The same principle applies to your toilet. If your home has older toilets, they likely use 3.5-7 gallons per flush. A modern low-flow toilet uses just 1.28 gallons. If replacing isn’t in your budget, placing a sealed water bottle filled with sand in the tank displaces water and reduces how much is used per flush.

8. Be Strategic With Hot Water

Heating water is the second-largest energy expense in most homes. You can reduce hot water costs by lowering your water heater temperature to 120°F — most are set to 140°F by default. This single adjustment can save 4-22% on water heating costs according to the Department of Energy.

Other hot water savings include washing clothes in cold water (modern detergents work just as well), taking shorter showers, and only running the dishwasher with full loads.

Gas and Internet: Often Overlooked Savings

9. Seal Drafts and Insulate

If your home feels drafty in winter, you’re literally paying to heat the outdoors. Air leaks around windows, doors, and electrical outlets are a major source of wasted energy.

Weatherstripping and caulking are inexpensive fixes — a $10 roll of weatherstripping and a $5 tube of caulk can seal most common air leaks. For larger gaps, foam insulation or door sweeps can make a significant difference. The Department of Energy estimates that sealing air leaks can save 10-20% on heating and cooling costs.

10. Negotiate Your Internet Bill

This is one of the easiest ways to save money on utilities, and most people never try it. Internet providers almost always have promotional rates or retention offers that they don’t advertise.

Here’s the approach that worked for me:

• Call your provider and say you’re considering switching to a competitor
• Ask to speak with the retention or loyalty department
• Mention a specific competitor’s price (research it beforehand)
• Be polite but firm — ask what they can do to keep your business

I’ve negotiated my internet bill down by $20/month using this approach, and it took one 15-minute phone call. That’s $240 saved per year for a quarter-hour of effort. This same bill negotiation approach works for other recurring expenses too — our guide on how to cut your monthly subscriptions covers more ways to trim recurring costs.

11. Bundle Services Strategically

If you’re paying separately for internet, phone, and streaming, you may be overpaying. Some providers offer bundles that are genuinely cheaper, while others bundle services you don’t need at inflated prices.

Before bundling, add up what you’re paying separately and compare to the bundle price — including any price increases after promotional periods end. Sometimes unbundling and choosing the cheapest provider for each service saves more than any bundle.

12. Check for Utility Assistance Programs

Many people don’t realize that utility companies, state governments, and federal programs offer assistance that can significantly reduce your bills:

• LIHEAP (Low Income Home Energy Assistance Program) — Federal program that helps eligible households pay heating and cooling bills
• Utility company rebates — Many offer rebates for energy-efficient appliances, smart thermostats, and weatherization
• Budget billing — Averages your annual utility costs into equal monthly payments, preventing seasonal spikes
• State energy assistance programs — Each state has programs for residents who qualify

Even if you don’t qualify for income-based assistance, checking for rebates and incentives on energy-efficient upgrades is worth the effort. Your utility company’s website usually lists available programs.

Create a Utility Savings Action Plan

Don’t try to do everything at once. Start with the changes that deliver the biggest savings for the least effort:

This week (free, immediate savings):

• Adjust thermostat by 2-3 degrees
• Unplug unused electronics
• Lower water heater to 120°F
• Fix any visible leaks

This month ($20-$50 investment):

• Replace remaining incandescent bulbs with LEDs
• Install low-flow showerheads and faucet aerators
• Apply weatherstripping to drafty windows and doors
• Call your internet provider to negotiate

This quarter (bigger investments, bigger returns):

• Install a programmable or smart thermostat
• Schedule HVAC maintenance
• Check for utility rebate programs
• Consider energy-efficient appliance upgrades when replacements are needed

This approach aligns well with a broader budgeting strategy. Our how to budget and save money for beginners guide covers how to prioritize these kinds of expense reductions within your overall financial plan.

How Much Can You Actually Save?

If you implement even half the strategies in this guide, here’s a realistic savings estimate:

• Thermostat adjustment: $100-$200/year
• LED bulbs: $50-$100/year
• Unplug phantom loads: $50-$100/year
• Fix leaks and low-flow fixtures: $50-$100/year
• Water heater adjustment: $50-$100/year
• Internet negotiation: $100-$300/year
• Seal air leaks: $100-$200/year

Total potential savings: $500-$1,100 per year

That’s real money you can redirect toward your emergency fund, debt payoff, or savings goals. Utility savings compound over time because they happen every single month — unlike one-time money moves, these savings keep working for you indefinitely.
