Start with a fair comparison
By RealCostTools. Sources and calculations checked September 16, 2026.
This guide is for U.S. households. All dollar amounts are U.S. dollars (USD); electricity rates are in cents per kilowatt-hour (kWh). Use local quotes and your utility rate rather than treating the examples as prices available in your area.
In the fictional refrigerator example below, a replacement saves $60 a year in electricity but costs $750 more upfront than a repair. Over five years, repairing costs $450 less, assuming both refrigerators last through the comparison and no other costs differ. Those assumptions matter as much as the price tags.
Use this guide to build your own comparison. The appliance electricity calculator handles the energy portion; repair quotes, installation, future repairs and remaining life need a separate worksheet.
Get a diagnosis and check coverage first
Start with the fault and a written repair quote. Record the model number, the diagnosed problem, parts availability, expected completion date and what the proposed repair covers. Ask whether the diagnostic charge is included in the quote or credited toward the work.
Check the appliance's warranty and any service contract before assuming you must pay the whole bill. Coverage can differ for parts, labor and particular failures. The FTC recommends reading the written terms and keeping the receipt; a separately purchased service contract is different from the warranty included with a product.
For a rented home, establish who owns the appliance and who should authorize work under your agreement before paying for a replacement.
Age helps frame the questions, but it does not tell you how long this particular appliance will last. Ask the technician whether the quote resolves the diagnosed fault, whether other problems are evident, and what uncertainty remains. Do not turn a general lifespan estimate into a promise of additional service.

Compare complete prices, not a repair quote against a shelf price
Make two lists of costs you would incur from today onward.
| Repair option | Replacement option |
|---|---|
| Remaining diagnostic or service-call charges | Appliance purchase price |
| Parts and labor | Sales tax and delivery |
| Tax and other quoted charges | Installation and required connection parts |
| Temporary arrangements while waiting | Removal and disposal of the old appliance |
| Any known follow-up work | Necessary fit or access changes |
| Less confirmed warranty coverage or credits | Less confirmed discounts, rebates or sale proceeds |
Ask for itemized quotes so charges are counted once. If a diagnostic fee has already been paid and cannot be recovered under either choice, it is a shared past cost: record it in your overall spending, but do not let it distort the decision between the remaining options. A fee credited only if you approve the repair changes the repair balance still due.
For replacement, confirm the model meets the same household need and fits the space. The FTC advises checking appliance dimensions, door opening and ventilation clearance.
Treat a possible rebate separately until you verify eligibility, the application process and payment timing. ENERGY STAR provides a rebate finder. A rebate paid later may reduce the eventual cost without reducing the cash needed on delivery day.

Calculate the electricity difference
For each refrigerator, collect a supported annual energy estimate in kWh and apply the same electricity rate:
Annual electricity cost = annual kWh × dollars per kWh.
Annual electricity savings = existing appliance cost − replacement cost.
EnergyGuide's dollar figure uses typical usage and a national energy-price assumption; it is not a quote for your home. Use annual kWh with your own rate. If the label is missing, check the seller's or manufacturer's website.
Our EnergyGuide article explains the inputs in more detail. Keep uncertain consumption estimates visibly separate from measured use. Do not assume an older refrigerator uses a particular amount solely because of its age.
Use the consumption-dependent charges relevant to your electricity savings. A fixed monthly customer charge usually remains after replacing an appliance. One flat rate is also only an approximation where prices depend on time or usage tiers. The electricity-rate guide explains the distinction between a bill rate and a state benchmark.

Worked example: a $350 repair or $1,100 replacement
Every input here is fictional. These are not national average repair prices, current retail offers or typical refrigerator consumption figures.
Assume the repair restores normal operation, both options provide five years of service, electricity stays at 20 cents/kWh, and the old refrigerator is removed if replaced. For this simplified comparison, assume no financing, further repairs, downtime costs or difference in ending resale value. These are undiscounted costs: future payments are added at their stated dollar amounts without adjusting for the time value of money.
| Input or calculated cost | Repair existing refrigerator | Buy replacement |
|---|---|---|
| Upfront cost, including applicable quoted charges | $350 | $1,100 |
| Annual electricity use | 700 kWh | 400 kWh |
| Electricity rate | $0.20/kWh | $0.20/kWh |
| Annual electricity cost | $140 | $80 |
| Five years of electricity | $700 | $400 |
| Upfront cost plus five years of electricity | $1,050 | $1,500 |
The replacement reduces electricity spending by $60 per year, or $5 per month on average. Its upfront premium is $1,100 − $350 = $750. Five years of energy savings recover $300 of that premium, leaving repair $450 cheaper under the stated assumptions.
That $450 is also a useful sensitivity check: an additional $450 of repair-path costs, with everything else unchanged, would erase the modeled advantage. This is a threshold, not a prediction of future breakdowns.
The energy figures were checked with the RealCostTools electricity engine. The five-year totals are separate worksheet calculations; the calculator does not produce a complete appliance repair-versus-replacement verdict.
Use payback carefully
For these two choices, electricity-only simple payback is:
Additional upfront cost of replacement ÷ positive annual electricity savings.
Here, $750 ÷ $60 = 12.5 years. That is longer than the five-year comparison, and it is not evidence that either appliance will last 12.5 more years. Simple payback omits financing, future repairs, changing rates and the timing of costs.
The starting point matters. When comparing replacement against repairing a broken appliance, subtract the repair cost you avoid. When comparing replacement against continuing to use a working appliance with no immediate repair needed, there may be no repair bill to subtract. Do not mix these two decisions.
If the new model has equal or higher electricity costs, a positive extra purchase cost has no electricity-only payback. Replacement might still solve another problem, but energy savings would not justify it.
Test the assumptions that could change your choice
An electricity rate is one source of uncertainty. Keeping every other input from the example unchanged gives:
| Illustrative electricity rate | Annual electricity savings from replacement | Five-year repair total | Five-year replacement total | Repair costs less by |
|---|---|---|---|---|
| 15 cents/kWh | $45 | $875 | $1,400 | $525 |
| 20 cents/kWh | $60 | $1,050 | $1,500 | $450 |
| 30 cents/kWh | $90 | $1,400 | $1,700 | $300 |
These are scenarios, not forecasts. Higher rates increase the value of using less energy, but replacement still costs more over five years in all three examples.
Remaining life can matter more. If the repaired appliance may last only two years, do not compare two years of service against five years from the replacement and call the cheaper total a winner. Either compare both over a shorter common period or include the replacement and running costs needed to complete the longer period. If that later purchase remains unknown, show a range or leave the longer-term decision unresolved.
Also consider future repair costs on either option, financing charges, temporary arrangements and any meaningful difference in resale value at the end. Only include future amounts you can reasonably support, and test uncertain ones separately. Past purchase prices are not new spending caused by today's decision.
Run the electricity part in the calculator
To reproduce the main example:
The alternative compares with the first appliance entered, using that row's quantity. It is not a replacement comparison against the sum of several unrelated appliances. See the electricity methodology for model boundaries.
Carry the energy costs into your repair worksheet. Record the upfront bills and payment dates separately: a lower multi-year cost does not mean the upfront payment fits this month's budget.
appliance electricity calculator ↗
- 1. Open the appliance electricity calculator.
- 2. Use one appliance row and select EnergyGuide / annual kWh in Appliance 1: usage model.
- 3. Enter 700 in Annual electricity from label and 1 in Quantity of this appliance. Rename the row so it clearly identifies the existing refrigerator.
- 4. Select My electricity bill under Where is your rate from?, then enter 20 in Electricity rate, which uses cents/kWh. This is the manual-entry setting; 20 is a fictional example, not a claim about your bill.
- 5. Expand Compare an alternative (optional) and enter 400 in Alternative appliance annual electricity.
- 6. Select Calculate my estimate and confirm $140/year, $80/year and $60/year savings in Current vs. alternative appliance.
Should I automatically replace an appliance when the repair costs half as much?
No single percentage completes the comparison. A repair-to-replacement ratio leaves out remaining life, operating costs, installation and warranty coverage. Use it as a reason to compare the options carefully, not as an automatic decision rule.
Does a more efficient refrigerator always save enough to justify replacement?
No. Lower energy use reduces operating costs at the same rate, but those savings may not recover the extra purchase cost within your ownership period. In the worked example, the new model saves electricity while still costing more over five years.
What if I keep the old refrigerator as a second fridge?
Then it is no longer a replacement-only energy comparison. Count the electricity for both appliances. ENERGY STAR recommends recycling an old refrigerator when replacing it and notes that many retailers offer pickup and recycling. Confirm the service and any fee with the seller.
Reference: ENERGY STAR: Refrigerators
Can I use this for a washer, dryer or dishwasher?
The same cost worksheet can help, but the relevant operating expenses differ. Add water, sewer, gas or other costs where applicable. The current RealCostTools calculator estimates electricity; it does not calculate those additional expenses or diagnose a fault.
Your decision worksheet
Use the comparison table and the six-item checklist below before choosing.
For a common comparison period, copy and fill in this compact worksheet. Keep rebates paid later separate from cash due now, and do not enter unknown future costs as zero without labeling that assumption.
| Cost over your chosen period | Repair | Replace |
|---|---|---|
| Upfront payment still due | Your quote | Your quote |
| Later confirmed rebate or credit, subtract once | Your amount | Your amount |
| Electricity and other operating costs | Your estimate | Your estimate |
| Additional repairs, financing and temporary arrangements | Your estimate or range | Your estimate or range |
| Later replacement needed to finish the period | Your estimate, if needed | Your estimate, if needed |
| Ending sale value, subtract if included | Your estimate | Your estimate |
| Total under these assumptions | Sum the above | Sum the above |
Start with your actual quotes, use the calculator for electricity costs, and keep the assumptions beside the result. A clear comparison should show what would change your decision as well as which option looks cheaper today.
