Calculating the true cost of an item

written by on 2024-12-27

How much does your phone really cost?

Price

Let's just say, for this discussion, that the price of your phone is:

$300

What you pay

The amount you pay is: Price + Sales Tax

Sales Tax (let's assume 0.08%) = 300 * 0.08% = $24

You pay: $300 + 0.08% = $324

How much did you have to earn to buy the phone?

You have to earn more than $324 since you pay income tax as well. For this thought, let's assume a 15% income tax.

$324 / (1–0.15) = $381

What if you didn't buy the phone and saved the money instead?

A simple hack to estimate what this would be worth in 30 years if invested is to *10.

If you didn't buy the $300 phone, you would be $3,810 wealthier in 30 years!
