What is included: all 19 calculators
- Landed Cost CalculatorWhat does one unit really cost you?The price on your supplier's invoice is not what a product costs you.
- Profit Margin CalculatorMargin or markup: what are you really keeping?Margin and markup are two different numbers from the same sale, and mixing them up is the most common pricing mistake there is.
- Wholesale Price CalculatorWhat should you charge a shop?A wholesale price has to leave room for two businesses: yours and the shop's.
- Break-Even CalculatorHow many do you need to sell each month?Before a product business makes a profit it has to cover its fixed costs: the bills that arrive whether you sell anything or not.
- Reorder Point CalculatorWhen should you order more stock?Order too late and you sell out. Order too early and your cash sits on a shelf.
- Selling Fee CalculatorWhat is left after the marketplace takes its cut?Marketplaces and card processors each take a slice of every sale.
- Sale Discount CalculatorWhat does a sale really cost you?A discount comes straight out of your profit, not your price.
- Markup CalculatorWhat price does your markup give you?Markup is the simplest way to set a price: take your cost and add a percentage.
- Inventory Turnover CalculatorHow fast does your stock turn into cash?Stock on a shelf is cash you cannot spend. Inventory turnover tells you how many times a year you sell through your stock, and how long each dollar waits.
- Cash Runway CalculatorHow long will your cash last?Businesses do not close because they lack profit on paper. They close when the cash runs out.
- Free Shipping CalculatorCan you afford to offer free shipping?Free shipping is never free: you pay the postage out of your profit.
- Bundle Pricing CalculatorWhat should you charge for a bundle?A bundle gives the buyer a saving and gives you a bigger sale.
- Ad Cost CalculatorDoes your advert make money?An advert is worth running when a sale earns more than the advert cost to win it.
- Labour Cost Calculator for MakersWhat is your time worth in each product?If you make what you sell, your time is a cost like any other.
- Batch Cost CalculatorWhat does one piece from a batch cost you?Candles, soap, bakes and small-batch anything are made many at a time and sold one at a time.
- Craft Fair and Market Stall Break-Even CalculatorHow many do you need to sell to cover the stall?A market day has its own costs: the table fee, getting there, the card reader.
- Inventory Value CalculatorHow much cash is tied up in your stock?Every unit on your shelf is money you have already spent. Count what you hold of your main products, put in what each one cost you, and see the total, the product holding the most, and how many months of sales it covers.
- Etsy Fee CalculatorWhat does Etsy take from a sale, and what do you keep?Etsy charges a listing fee, a transaction fee and a payment processing fee on every sale, plus an Offsite Ads fee when an ad brought the buyer.
- Etsy vs Shopify vs Your Own Site CalculatorWhich keeps more profit: Etsy, Shopify or your own website?Etsy charges per sale. Shopify charges a monthly plan plus card fees.
Why a membership?
- Prices, fees and costs change, so the sums need redoing every time you launch, restock or run a sale.
- One wrong price can cost more than a year of membership. Checking it takes a minute.
- Everything is in one place, in plain English, built for people who make and sell products.
Questions
What do the 5 free calculations mean?
Each time you open a calculator and change a number, that is one calculation. You get 5, across any of the calculators, so you can see exactly what they do before you pay.
How do I cancel?
Reply to your Stripe receipt or email us, and we cancel it the same day. You keep access until the end of the month you paid for.
Does it work on my phone and my laptop?
Yes. After you pay, you get a personal unlock link. Open it on each device you use.
Is my data sent anywhere?
No. Your numbers are worked out and saved in your own browser. We only check with Stripe that your membership is active.
Do I need Excel?
