1.
degree of completion; level of perfection; polish; quality of finish
How well-finished or polished something is. Used to evaluate the quality, refinement, or thoroughness of a product, artwork, performance, or other work.
完成度が高い。
The level of polish is high.
この映画は完成度の高い作品だ。
This movie is a highly polished work.
まだ試作品なので完成度は低いが、方向性は良い。
It's still a prototype so the level of polish is low, but the direction is good.
Composed of 完成 (completion, perfection) + 度 (degree). The suffix 度 creates a scale or measure, so 完成度 literally means 'degree of completion.' In practice, it is more about quality and refinement than mere completion — a high 完成度 means something is well-crafted and polished.
COMMON COLLOCATIONS:
- 完成度が高い: high quality; well-polished
- 完成度が低い: low quality; rough; unfinished
- 完成度を上げる: to raise the quality; to refine
- 完成度の高い作品: a polished work
USAGE:
Very common in reviews and evaluations of creative works, products, and performances. Often used with 高い/低い rather than 大きい/小さい.
