Do the math
What does a $7 coffee every day cost over 10 years?
The Simple Answer
A $7 coffee every day costs $2,555 a year, which is $25,550 over ten years.
Small daily amounts hide in the background of a budget. Turning one into a yearly figure shows what it really weighs.
One $7 coffee, every day
A year: $7 × 365 days = $2,555
Ten years: $2,555 × 10 = $25,550
A month, on average: $2,555 ÷ 12 = about $213
Ten years actually contain 3,652 or 3,653 days once the leap days are counted, so the real total is $25,564 or $25,571. We use 365-day years because it keeps the sum simple and the difference is small.
If you only buy it on weekdays
Most people do not drink the same coffee seven days a week. A year has 52 weeks of five weekdays, which is 260 days. At $7 that is $1,820 a year and $18,200 over ten years. The two answers sit side by side because the real number depends on how often you actually buy one.
| Price per day | One year | Ten years |
|---|---|---|
| $3 | $1,095 | $10,950 |
| $5 | $1,825 | $18,250 |
| $7 | $2,555 | $25,550 |
| $10 | $3,650 | $36,500 |
The interesting part
The sums do not tell you whether the coffee is worth it. That is your call, and a good coffee can be worth a lot to a good morning. What the arithmetic gives you is a fair comparison. Switching from $7 to $3.50 saves exactly half, which is $1,277.50 a year. Skipping every other one saves the same. You can set that against whatever else you would do with the money and decide for yourself.
The same trick works for anything that repeats: a streaming service, a lunch, a parking fee. Multiply by the number of times it happens in a year and look at the result.
Monthly vs Annual Subscription: Turn a monthly payment into a yearly cost and see whether paying for a year costs less.
