With Margin

Explore With Margin, an iOS, iPadOS, and macOS app to help calculate the return on investment of flips.
The recent rise of garage sale resellers and thrift store flippers empowers everyone to give items a second chance at life while exploring one's entrepreneurial drive. From collectible film cameras to '80s vintage shirts to a set of tools, flippers keep products from ending up in landfills while finding them new, loving homes.
With Margin is a straightforward yet effective profit and loss estimator providing anyone on the go quick access to determine a find as a possible hit or miss. Utilizing fixed or percentage-based costs, quickly enter your reasonably educated guess for the amount it could sell. Next, subtract shipping, item cost, marketplace fees, and payment processing fees (if applicable). If profitable based on your industry knowledge, you can quickly act upon it.
Tip: While using the Custom calculator, tap the percent (%) icon to turn the line item value into a percentage rather than a fixed cost; this is useful for percentage-based fees.
