Long Tail Ratio Calculator
A long tail ratio calculator answers a simple distribution question: of everything you sold, how much came from niche items rather than bestsellers?

-
Garage Sale Value Calculator
Pricing is the hardest part of a garage sale. Price too high and shoppers walk past; price too low and you give away money.
-
Thrift Value Calculator
Wondering what that thrift store find, closet cleanout item or donation pile is actually worth?
-
Register Value Calculator
Closing a register should not require a spreadsheet and a prayer.
-
Convenience Store Profit Calculator
A convenience store can ring up impressive daily sales and still keep almost none of it.
-
Pawn Shop Offer Calculator
The number that matters at the pawn counter is not what you paid. It is the item’s resale value: what it would sell for used, today.
-
Wholesale Offer Calculator
A supplier quotes $250 and you want a 35% margin. What is the most you can offer without giving that margin away?
-
Cost To Retail Ratio Calculator
The cost-to-retail ratio tells you what share of the selling price is eaten by cost: a 60% ratio leaves a 40% gross margin, and confusing the two numbers is how retailers quietly underprice a whole product line.
-
Consignment Percentage Calculator
In a consignment deal, a shop sells your item and keeps an agreed percentage.
-
Sales Per Square Foot Calculator
Rent is charged by the square foot, so the fairest way to judge a store is by the square foot too.
22 tools
Selling and stock tools come first: the Sell Through Rate Calculator, average weekly sell through, the Sales Per Square Foot Calculator, time between orders and clearance percentage, plus a change calculator for the till and a cost per item tool for the shelf edge. Inventory shrinkage percent measures the stock that goes missing, and cost to retail ratio and long tail ratio set slow and fast lines against each other.
Shop and second-hand tools make up the rest. The Convenience Store Profit Calculator and gas station profit cover the small-format shop, while the Garage Sale Value Calculator, thrift value, pawn shop offer, wholesale offer, consignment percentage and register value cover selling on, second-hand and in bulk. Price per quart, price per 100g and price per screw, plus diamond cost per carat, give the per-unit comparisons that shoppers and small sellers actually use.
