DCF840 covers more than one configuration. DeWalt uses it as a family number — sellers list both the bare tool and the kit with batteries under it, and the part number alone does not say which. The figures above span both, so the range is wider than for a single configuration. Check each listing's title for what is actually included.

Common questions about the DeWalt DCF840

How much is a used DeWalt DCF840 worth?
The median asking price for a used DeWalt DCF840 is $81.35, across 60 listings currently live on eBay. Most sit between $62.51 and $100.33. This is what sellers are asking today, and it is refreshed daily.
What is a fair price to pay for a used DeWalt DCF840?
Anything at or below $62.51 is cheap relative to the rest of the market — that is the 25th percentile of 60 live listings. Above $100.33 you are paying more than three quarters of sellers are asking. The middle half of the market runs $62.51 to $100.33. The cheapest listing right now is $44.95 delivered.
Is it worth buying a DeWalt DCF840 used instead of new?
A used DeWalt DCF840 asks about 81% of what the same tool costs new on eBay — $81.35 used against the new median. That is a moderate saving, so it comes down to how much the warranty and condition are worth to you.
How much do used DeWalt DCF840 prices vary?
Half of the 60 live listings sit within a $38 window, $62.51 to $100.33. The tightest $20 window holds 20 of 60, $55 to $74. 45 of 60 (75%) are asking under $100. These are asking prices across listings live on eBay, so the spread shows how much sellers disagree rather than how much the tool actually sells for.
What should I sell my used DeWalt DCF840 for?
Price it around $81.35 to sit mid-market, or at or below $62.51 to undercut three quarters of the 60 listings you are competing with. $100.33 is the top of the normal range. These are asking prices rather than sold prices, so they tell you where to start rather than what you will get, and buyers compare delivered cost — price with shipping in mind.
How many used DeWalt DCF840 are for sale right now?
60 listings for the DeWalt DCF840 are live on eBay right now, ranging from $44.95 to $161.32. We verify each one names this exact part number and is the whole tool rather than a part or an accessory.
Does the DeWalt DCF840 come with a battery?
It depends on the listing. DCF840 is a family number rather than a single product — DeWalt sells the bare tool and the kit under part numbers that both begin with it, and sellers routinely write just DCF840. The figures on this page cover both configurations, which is why the range is wider than for a single one. Check the individual listing title for what is included.
