Your Coffee By the Numbers

The average American drinks 3.1 cups of coffee per day, according to the National Coffee Association. At an average price of $4.50 per cup (for a coffee shop latte), that works out to over $5,000 per year. Over a 40-year coffee career, you could spend more than $200,000 on coffee. If you invested that money instead at 7% annual returns, you would have over $1 million.

How Much Caffeine Is That?

A standard 8-ounce cup of brewed coffee contains about 95 mg of caffeine. The FDA considers 400 mg per day (about 4 cups) safe for most adults. That means your daily caffeine intake from 3 cups is roughly 285 mg, well within the recommended range. Over a lifetime, though, those milligrams add up to kilograms.

How many cups of coffee is too many?
The FDA recommends no more than 400 mg of caffeine per day for most adults, which is roughly 4 standard cups of brewed coffee. However, sensitivity varies by individual. Pregnant women are advised to stay under 200 mg. If you feel jittery, anxious, or have trouble sleeping, you may want to cut back.
Is coffee good for you?
Research suggests moderate coffee consumption (3-5 cups per day) is associated with lower risk of several diseases including type 2 diabetes, Parkinson's, and certain cancers. However, individual responses vary, and heavy consumption can cause anxiety, insomnia, and digestive issues.
How much money can I save making coffee at home?
Home-brewed coffee costs roughly $0.25-0.75 per cup versus $4-6 at a coffee shop. Switching from daily shop purchases to home brew can save $1,000-1,500 per year. Even upgrading to premium beans and a quality grinder still costs a fraction of shop prices.
