English Idioms Book On Sale From July 6-10, 2017

Learning American English idioms is important for learning to speak English fluently. I wrote a book of the 250 most common idioms that are used in business English. These are idioms I have heard frequently while working in American companies during the last 30 years.

If you can learn one new idiom a day, your English speaking skills will be much higher.

Today’s idiom is:

back-of-the-envelope calculations

A rough calculation.

My back-of-the-envelope calculation is that this product will be at breakeven within a year.

Origin

Back-of-the-envelope describes when a person grabs any available piece of paper (such as an envelope or piece of scrap paper) to make a quick calculation with a pen or pencil. Since the calculation is done in haste and without a calculator or spreadsheet, the implication is that the calculation is rough, not 100% accurate.
