The Money Cycle: pure compounding. Why speed matters more than margin.
Most sellers obsess over profit margins. Smart sellers obsess over Velocity. See how shortening your prep time accelerates your cash flow and multiplies your capital over time.
Jump to calculatorTwo sellers, same money, different speeds.
Imagine two sellers, Alex and Ben. Both have £10,000 and make 10% ROI per sale.
-
Alex (slow cycle)
Takes 3 months to buy, prep, and sell. Turns cash 4 times a year.
-
Ben (fast cycle)
Fast prep & shipping. Turns cash 6 times a year.
The result? With the exact same capital, Ben makes 60% more profit annually — just by moving faster.
The power of compounding.
In Amazon FBA, you don't just earn profit — you reinvest it. This creates a snowball effect. The faster you roll the snowball (prep & sell), the bigger it gets.
A delay of just 6 days in prep doesn't look like much on a calendar. But over 4 years, those 6 days prevent your snowball from rolling dozens of extra times.
