Retail Calculators

Running a shop means watching stock move and money come back. These tools track both sides: how fast goods sell, what a square foot of floor earns, and what disappears along the way. They suit small retailers, market traders and anyone pricing second-hand goods.

Milk comes in gallons, juice in half-gallons, motor oil in quarts, and paint in liters, and the biggest package is not always the best deal.

Which pack is really cheaper?

Bulk screw prices hide the real unit cost in packaging, shipping, and tax.

Sell through rate answers a simple question: of all the stock you had available to sell, what share actually sold?

A customer hands you a $20 bill for a $17.35 sale and the line behind them is growing.

A gas station profit calculator has to model the industry’s strangest open secret: the fuel that brings everyone onto the lot is barely profitable, and the coffee inside pays the bills.

Sell-through rate answers the buyer’s hardest question in one number: of the stock you brought in, how much actually sold?

Twelve orders in 33 days means customers buy roughly every 3 days, not every 2.75: twelve orders create eleven gaps, and the average gap is the total span divided by the number of gaps.

Your records say one number, the shelf count says a smaller one, and the gap between them is money already spent and never recovered.

The phrase clearance percentage means two different things depending on who is asking.
