Prices typically range from about $150 to $700 depending on whether you buy a remanufactured unit, an aftermarket new unit, or the original-equipment manufacturer (OEM) part, with installation costs extra.
This article explains the cost landscape for replacing the alternator on a 2020 Honda Accord, including price ranges by source, factors that influence price, and tips to save on parts and labor.
What determines the price
Several factors influence the cost of an alternator replacement, including whether you buy OEM from a dealer, an aftermarket unit, or a remanufactured/refurbished part; the amperage rating and compatibility with the 2020 Accord's engine option; core charges; regional labor rates; and whether the installation is done at a dealership, chain shop, or independent shop.
OEM vs aftermarket
Official Honda parts are typically the most expensive but may come with the best warranty and guarantee of fit. Aftermarket units can offer substantial savings while still meeting performance specs.
Price ranges by type
Below is a snapshot of typical parts prices you might see in the U.S. market. Note that some vendors include a core charge unless you return your old unit.
- New OEM (dealer or Honda-approved): generally around $350–$700 for the part.
- New aftermarket replacement: typically $150–$320.
- Remanufactured/rebuilt: commonly $100–$250.
- Used/Takeout or refurbished: about $60–$150, depending on condition and availability.
Installation labor is usually extra, often $80–$200 depending on location and shop hourly rates. In total, you might expect $230–$900 for a full replacement including labor.
Price ranges by retailer/source
Shop around across dealers, auto parts stores, and online retailers to compare total cost, including core charges and shipping where applicable.
- Honda dealership or official parts: part price commonly $350–$700, with labor extra.
- Major auto parts chains (AutoZone, Advance Auto Parts, NAPA): new units typically $180–$320; remanufactured $100–$250; core charges may apply.
- Online retailers (RockAuto, Amazon, eBay storefronts): widely variable; new parts often $150–$330, remanufactured $90–$180; check shipping and warranty.
- Local independent repair shops: parts $150–$350 depending on brand; labor typically $90–$180 per hour.
Tips: verify compatibility with your engine variant and the amperage spec, read warranty terms, and factor in installation labor and potential core charges when comparing quotes.
What to check before you buy
Before purchasing, confirm the exact alternator specifications for your 2020 Honda Accord — such as amperage (to match the electrical load), mounting pattern, and belt routing. Also confirm the presence of a core charge, warranty length, and whether the part is new, remanufactured, or refurbished.
- Engine variant and amperage rating (1.5L vs 2.0T variants) to ensure proper fit.
- Correct mounting and pulley alignment; check belt routing.
- Warranty duration and coverage (at least 1 year is common).
- Core charge policy and return options for the old unit.
- Installation labor estimate and whether a diagnostic check is included.
With the right part and a trusted installer, the Accord's electrical system should be back to normal function with reliable performance.
Summary
For a 2020 Honda Accord, expect the part price to range from roughly $60 to $700 depending on condition and source, with labor typically adding $80–$200. The most economical choice is usually a remanufactured or aftermarket unit with a solid warranty and included core policy, while OEM parts from a dealer come with fit guarantees at a higher price. Always verify amperage and compatibility, and compare multiple quotes to balance cost with reliability.
