は～くらいです

は～くらいです is used to indicate an approximate amount, quantity, time, cost, or extent. The phrase sets the topic (with は) and then states an estimate using くらいです. It’s common when you want to give a rough figure that’s not exact. In everyday conversation, you can talk about money, time, distance, counts, or even extent of something by citing a figure or demonstrative like このくらい to show “about this much.” Note that くらい often follows a number or a demonstrative (この/その/あの) to specify the rough amount. The nuance is casual and practical, focusing on estimation rather than precision.
