PENNY WISE AND POUND FOOLISH

Have you ever gone out of your way to save a few bucks by making a compromise and later land up spending a huge amount due to your foolishness? The idiom 'penny wise and pound foolish' basically means to save a little money, only to lose a greater amount due to your own foolishness. A penny is a small amount and a pound is a larger amount, so you are wise with a small amount but foolish and wasteful with larger amounts. It also means you are over careful about unimportant and small matters and careless about important ones.

You realize that in the process of being stingy about small expenditures, you eventually spend more than you actually saved. For example, if you save a few hundred bucks by not hiring a tax accountant to review complicated matters, you are penny wise and pound foolish as you ultimately land up paying a huge penalty amount.
