Sales data

Why bother doing mental maths in your head when there are tools that will do it for you? Sure, there’s the novelty of being able to mentally workaround figures, but there can be a lot and the whole process is prone to (expensive) human error. Instead of risking your livelihood, check out one of these ten free ecommerce cost calculators that RepricerExpress unearthed for you.

1. Amazon: Fulfillment by Amazon Revenue Calculator

Amazon FBA calculator

Amazon provides a lot of services to their sellers, and their FBA revenue calculator is just one of many. Start by selecting your country in the top right corner, then type in the product name in the search bar for the rest. It’ll give you a pretty good idea of the FBA fees that accompany that product so you’ll know how to price the item for the best profit gains.

You can access the FBA revenue calculator via Seller Central.

2. Algopix: Conversion Rate Calculator

If you want to get firsthand knowledge of how user engagement translates to a conversion (whether that’s an email signup, sale or something else), Algopix has you covered. Their calculator is right there on the homepage, allowing you to quickly and easily plug in your numbers to find out your conversion rates.

And if that’s not enough for you, scroll down to the bottom where they also have tools to help you convert ASINs to UPCs, ASINs to EANs, EANs to UPCs, and calculate eBay fees.

3. TaxJar: Sales Tax Calculator

Nobody likes paying sales tax, but TaxJar makes the whole thing as painless as possible if you’re selling in the United States. All you have to do is enter in a zip code (at the minimum, with street address for better accuracy for certain states), and they’ll return you the sales tax rate.

Plus, if you sign up for their sales tax API demo, you can calculate sales tax with extra information like product exemptions, sourcing logic and shipping taxability.

They break down their calculator in a detailed post with everything you need to figure out the cost per order (CPO), helping you understand what your fulfillment costs are — and which areas of them you can save money in.

Red Stag Fulfilment

Amazon calculates its storage and fulfilment fees based on product’s weight and dimensions, so Red Stag Fulfillment’s calculator can give you a quick and easy way to check if it’s cheaper to go with Amazon or another company. Type in the item’s weight in pounds, followed by its length, width and height in inches, and they’ll tell you how much UPS, FedEx and USPS will charge for each of their zones.

7. Impact Masters: Cost of Lost Customers Calculator

Another area of loss you probably won’t escape on Amazon is that of customers. It’s just about impossible to retain 100% of your customer base, but Impact Masters can help you figure out what that potential cost will be.

They’ll factor in things like average sale amount, number of sales per year, number of annual negative reviews, number of lost customers per review and more, then give you back a number of figures you could reasonably expect when selling online.

8. EasyCalculation: Email Marketing ROI Calculator

Email marketing is just about a necessity these days, but do you know what the ROI on your campaign is? If not, start using EasyCalculation to find out. They account for currency type, audience size, campaign cost, response rate, conversion rate and average purchase so you can see which areas need bolstering or trimming.

They’ll assist in you calculating when to reorder stock at the right time so you have enough on your shelves to satisfy buyers, but not so much you’ll be paying long-term storage fees.
