Mauro Stendel explains two essential calculations that anyone investing or starting a business must know. He first compares putting $1,000 in a fixed‑term deposit at a typical 4 % annual interest, which yields $1,040 after one year, with using the same capital to launch an online store. Assuming the inventory can be turned twice a month (24 turns per year) and each turn yields only a 4 % margin, the compounded result would be about $2,563.30 after a year. Stendel emphasizes that a 4 % margin per product in an online store is extremely low—calling anyone who achieves only that a “burro” (fool). He notes that many sellers achieve 60 % or higher margins, and even in the worst‑case scenario of 4 % per turn, the turnover frequency dramatically outperforms a fixed‑term deposit. He then offers a free private class (available to commenters) that teaches how to find products with much higher returns, stressing that the higher‑margin strategy can generate far more wealth over a year.
