Operating an e-commerce business means wearing a lot of hats. Sometimes you’re the chief marketing officer; other times you’re the warehouse manager. With so many different tasks involved in running your online store, you’ll take all the help you can get.

Everything from evaluating sales tax to the risk you run of being hacked — is purchasing cyber insurance worth it? — can stack up. The next time you find yourself performing the unenvious task of compiling a spreadsheet with lots of headache-inducing equations, try Googling “storage space calculator” or whatever it is you’re trying to figure out.

I’ve gone ahead and compiled a number of nifty free calculators that most e-commerce business owners could do with. If you’ve got a favorite that’s not on here, I’d love to know — please share it in the comments below!

DIM Weight Сalculator

If you handle order fulfillment yourself, your back probably isn’t the only thing that’s a pain.

Trying to figure out whether it’s cheaper to send your package to Marianne in Marietta, GA via FedEx or UPS involves calculating dimensional weight, or DIM weight if you want to be fancy.

The folks at Red Stag Fulfillment make it easier for you to determine the cheapest shipping rate with their easy to use and free DIM weight calculator. Just plug in the weight and dimensions of the package you’re shipping and the calculator does the rest.

D’oh! If you had used TaxJar’s Sales Tax calculator, you wouldn’t have freaked out. That’s because their database of state, county, and local sales taxes turns up a flat 0% for Wanda’s ZIP code. Use this free calculator and save yourself the trouble of assessing sales tax nexus.

Reorder Point Formula

Running out of stock because your web store sells the next big fad toy that every parent is buying for their kid’s birthday is a good problem to have.

The moment you lose a sale because your new inventory is still halfway across the country on a freight truck headed to your warehouse is when it becomes a bad problem.

This is the sort of problem you want to prevent from happening; the solution is to calculate the optimal reorder point. Tradegecko’s reorder point formula minimizes the possibility of delays while ensuring that you don’t order new inventory too soon and end up eating up resources because now you have to pay for extra storage space in the fulfillment warehouse.

Online Checkout Conversion Calculator

Are you getting ten thousand visitors per day to your e-commerce and somehow only 20 walk away as customers?

You’re probably overdue for a diagnostic to figure out what in the name of Jeff Bezos is going on. An online checkout conversion calculator can determine if your servers have a high rate of kicking visitors off the site as they add items to their basket.

It might find that your decision to ask customers to create a profile with a username and complicated alphanumeric password has backfired. Whatever it is that’s holding you back — even if you think nothing is wrong with your website’s design and UX  you won’t know till you find out.

Credit Card Fraud Cost Calculator

Speaking of credit card acceptance, if you do business on the internet it’s inevitable that you’re going to see an occasional chargeback.

When a fraudster tries to order one of your website’s fancy gadgets using someone else’s credit card and the victim inevitably cancels the order or charges it back after it’s gone through, you’re usually the one who fits the bill.

Yeah, it’s not even your fault, but that’s unfortunately how things go in the cyber payments industry. Besides implementing security measures such as asking for ZIP code verification and CVV numbers, you should price your products to allow for something in the range of 1% chargebacks.

This free calculator from Kount will help you determine how much fraud can cost your business and estimate your margins based on the cost.

So simple to use – even my most technophobic clients can manage. Easy to install, quick to set up. Light years ahead of other shop plugins.
I’m so impressed I’ve recommended it to my website clients and am now using it for my own store along with four others for which I webmaster. Beautiful coding, excellent top-notch support, great documentation, fantastic how-to videos. Thank you so much Ecwid, you rock!
I’ve used Ecwid and I love the platform itself. Everything is so simplified it’s insane. I love how you have different options to choose shipping carriers, to be able to put in so many different variants. It’s a pretty open e-commerce gateway.
Easy to use, affordable (and a free option if starting off). Looks professional, many templates to select from. The App is my favorite feature as I can manage my store right from my phone. Highly recommended 👌👍
I like that Ecwid was easy to start and to use. Even for a person like me, without any technical background. Very well written help articles. And the support team is the best for my opinion.
For everything it has to offer, ECWID is incredibly easy to set up. Highly recommend! I did a lot of research and tried about 3 other competitors. Just try ECWID and you'll be online in no time.
