The 50 percent rule, exactly as Consumer Reports states it
In its January 2014 repair-or-replace findings, Consumer Reports wrote: “No matter who does the repair, don’t spend more than 50 percent of the cost of a new product on repairing an old one.”
In practice:
| New equivalent costs | 50% line | Repair quote | Rule says |
|---|---|---|---|
| $1,000 | $500 | $350 | Repair (35% of new) |
| $1,000 | $500 | $650 | Replace (65% of new) |
| $700 | $350 | $400 | Replace (57% of new) |
These are worked examples, not price data.
The rule compares a repair with the price of a comparable new model. It doesn’t consider age. That’s why the calculator above also shows how much of the appliance’s typical life is already used up.
What the calculator uses
- Appliance: refrigerator, washer, dryer, dishwasher, range or tank water heater.
- Age in years: from the serial number if you don’t know it. See our guides for Whirlpool, GE, LG and other brands.
- Repair quote: the full amount, including the service call and parts.
- Price of a new equivalent: a comparable new model’s price, plus delivery or installation if you would pay for it. For a water heater, use the installed price: a new heater always needs installing.
It compares your quote with 50% of the new price, then sets the age against these typical lifespans from our lifespan pages:
| Appliance | Low | Typical | High |
|---|---|---|---|
| Refrigerator | 9 | 12 | 13 |
| Washer | 5 | 10 | 15 |
| Dryer | 10 | 13 | 14 |
| Dishwasher | 9 | 10 | 15 |
| Range | 13 | 15 | 17 |
| Water heater (tank) | 8 | 11 | 15 |
Basis: our estimate, the median of NAHB, InterNACHI, Consumer Reports and US DOE figures (ENERGY STAR in place of DOE for refrigerators; no Consumer Reports figure for ranges, gas and electric combined). Details: refrigerators, washers, dryers, dishwashers, water heaters. For water heaters the figure is our summary of DOE, NAHB, InterNACHI and manufacturer figures (typical 11 years, between NAHB’s gas and electric figures; low 8 from the manufacturers; high 15 from DOE).
Lifespans are in years. For ranges, the sources disagree on fuel type. NAHB lists gas ranges at 15 years and electric at 13. DOE’s 2024 analysis estimates 14.5 years for gas cooking products and 16.8 for electric.
Typical repair costs by appliance
Three independent trade guides, plus Consumer Reports’ member survey for comparison. The guides disagree, so we show each one. The calculator uses the middle of the three (the median of their low ends and of their high ends).
| Appliance | Angi (2026) | HomeGuide | Fixr (2025) | CR survey median | We use |
|---|---|---|---|---|---|
| Refrigerator | $150 to $400 | $125 to $500 | $350 to $500 | About $150 to $240 for common problems; $562 for compressors | $150 to $500 |
| Washer | $180 to $250 | $100 to $400 | $150 to $400 | $123 to $214 depending on type | $150 to $400 |
| Dryer | $100 to $430 | $100 to $300 | $100 to $200 | $116 to $200 depending on fuel and price | $100 to $300 |
| Dishwasher | $175 to $325 | $100 to $300 | $100 to $300 | About $142 | $100 to $300 |
| Range | $108 to $310 (stove and oven) | $150 to $350 (oven) | $150 to $400 (oven) | $206 (gas $191, electric $212) | $150 to $350 |
| Water heater | $228 to $1,017 | $150 to $700 (tank) | $150 to $750 | not in the survey | $150 to $750 |
Trade estimates, labor included, as of September 2026. HomeGuide and Fixr are independent of Angi; HomeGuide pages are titled 2026 but were first written in 2023–24, and Fixr pages were updated in 2025.

Water heaters: repair or replace
- A leaking tank can’t be repaired. Bradford White: “Even a small leak means that a water heater will need to be replaced, because leaks are unable to be fixed.” A.O. Smith says corrosion from hard water “cannot be repaired and will eventually require tank replacement.” A leak from a valve or fitting is different and can often be fixed.
- The 50% rule applies here too. Rheem: “[I]f repair costs exceed 50% of the price of a new unit, replacement is almost always the better investment.” Bradford White says the same.
- Compare with the installed price. A new water heater has to be installed, so the calculator uses installed prices:
| New heater, installed | Angi (Jul 2026) | HomeGuide | Fixr (Jan 2026) | We use |
|---|---|---|---|---|
| Standard tank, 40–50 gal | $882 to $1,826 | $600 to $3,100 | $600 to $2,500 | $600 to $2,500 |
| Gas tank | $882 to $1,826 (tank-style; no tank-only fuel split) | $900 to $3,100 | $700 to $2,500 | $882 to $2,500 |
| Electric tank | $882 to $1,826 (tank-style; no tank-only fuel split) | $600 to $1,800 | $700 to $1,900 | $700 to $1,826 |
| Tankless | $1,400 to $3,900 | $1,400 to $5,600 | $1,000 to $4,000 | $1,400 to $4,000 |
| Hybrid heat pump | $3,200 to $4,700, average $4,200 (its heat pump page; $2,800 to $8,000 at the extremes) | $2,000 to $4,600 | $1,200 to $4,600 | $2,000 to $4,600 |
Trade estimates, unit plus labor. Angi’s page gives two tank figures: “Tank-style water heater replacement costs $882 to $1,826”, and elsewhere $600 to $2,500 depending on tank size; we use the first. HomeGuide’s main page is dated January 2026; its gas and electric figures come from its 40- and 50-gallon pages, dated January 2024. “We use” is the median of the three guides’ low ends and of their high ends. Local prices, permits and code upgrades can move the total a lot; get two installed quotes. For costs by size, labor and state, see water heater replacement cost.
How age changes the answer
Consumer Reports’ appliance-by-appliance guidance (and, for water heaters, Rheem’s) adds context the 50% rule leaves out:
- Refrigerators: “if your refrigerator is less than 10 years old, it’s usually more economical to get it fixed.” Budget top-freezers and side-by-sides near the 10-year mark are the exception.
- Washers: CR notes a washer’s life expectancy is “close to 10 years, on average,” which makes a middle-aged washer a harder call.
- Dryers: CR compares the repair with what the dryer cost. A 9-year-old $600 dryer needing a $118 repair may justify replacement. A $188 repair on a $2,200 dryer is “probably a worthy investment.”
- Dishwashers: “With dishwashers, the data typically leans toward replacement.” CR says they lose value faster than you might realize.
- Water heaters: Rheem says repair makes sense when a heater is “under 6–8 years old, shows no signs of tank corrosion or structural leaks, and repair costs fall well below 50% of replacement,” and that units over 10 years old are more likely to have more failures soon after one is fixed.
- Ranges: “the data tends to point to repairing your range.” CR’s example: a $212 repair on a low-end $800 electric range is less justified after a few years, while a premium $1,250 range typically stays worth repairing for at least a decade.
When to set the rule aside
- It’s covered for free. Check the manufacturer’s warranty first. CR notes it’s usually for the first year of ownership. Also check for a recall, since a recall remedy may cover the fix. Use our recall check or search CPSC.gov.
- The unit is at or past its typical life. A repair under 50% may only buy a little time. Compare the age with the typical lifespans above.
- Running costs matter to you. ENERGY STAR says an old refrigerator uses about 20% more energy than a certified model, so replacing can cut the monthly bill.
- It’s a safety issue. Gas smells, scorching or electrical faults call for a qualified, licensed technician, not a DIY fix or a price comparison.
- Waste matters to you. Consumer Reports cites EPA figures: 5.3 million tons of waste came from large appliances in 2018, with 2.1 million tons landfilled. Repairing keeps an appliance out of that stream.
Warranties, service contracts and home warranties
- Warranty vs. service contract. The FTC explains that an extended warranty or service contract “costs extra and is sold separately from a product.” It is different from the warranty that may come with the product, and it may duplicate coverage you already have.
- Buying used “as is.” The FTC notes that implied warranties cover products even without a written warranty, unless the seller gives written notice that there’s no warranty or marks the product “as is,” where state law allows. Read the listing or receipt before you rely on a seller to cover a repair.
- Extended warranties and satisfaction. Consumer Reports’ 2014 findings said simply: “Warranties don’t improve satisfaction.”
- Home warranties. Consumer Reports describes them as service contracts. It says you pay per-visit copayments on top of an annual plan price of about $600 to $1,200. Claims can be denied for preexisting conditions, lack of routine maintenance or improper installation, and payouts are capped. CR suggests self-insuring by putting that money into savings instead. The DC Attorney General’s consumer alert adds that service fees are typically $75 or more per repair. It advises reading the contract for what is not covered rather than relying on a salesperson.
We don’t sell or recommend any warranty or home warranty plan.
Limitations
- The 50% rule is a rule of thumb, not a guarantee. A second part can fail next month.
- Repair costs are national trade estimates and vary by region, brand and technician.
- Lifespans are averages. The calculator can’t see your appliance’s condition.
What to do next
- Check how much life is typical: refrigerators, washers, dryers, dishwashers, water heaters
- How old is it? Find the date in the serial number: appliances or water heaters
- Replacing with a used unit? Start with the used appliance buying checklist
- Selling the old one? See how much your used appliance is worth and where to sell used appliances
