Tradeoff vs. Trade-off vs. Trade Off
For the noun describing a compromise or balance between competing benefits, Cambridge documents both “tradeoff” and “trade-off.” The verb is written as separate words in constructions such as “trade one advantage off against another.”
Use “tradeoff” or “trade-off” for the noun; Cambridge documents both. Use the spaced “trade off” in the verb construction “trade something off.”

Quick tests
Noun-or-verb test
Is the expression a noun naming a compromise between competing benefits?
If yes: Use documented noun spelling “tradeoff” or “trade-off” according to style.
If no: For the verb construction, write “trade” and “off” as separate words.
Caveat: The reviewed sources support both noun spellings; this is not a claim that one noun form is universally required.

“Tradeoff” is a documented closed noun spelling.

Further guidance
Core difference
Use the documented noun or modifier form when naming a thing, result, person, or concept; use the spaced form when the words function as a verb.
Fast Test
If the expression can take ordinary verb tense or inflection in the sentence, the spaced verb form is usually the relevant choice.
Variant Boundary
Cambridge records “tradeoff” with “trade-off” as a noun variant and separately records the phrasal-verb construction “trade something off.”
