Questions you probably have
Everything about pricing, accounts, formulas, and how ZeroNova works.
Are ZeroNova dropshipping calculators actually free?
Yes. Every calculator, every result, forever. ZeroNova has no paid tier, no credit card requirement, and no trial period. You create an account with email and password, and every tool is yours to use unlimited. There is no upgrade prompt, no 'pro' version, and no hidden fees.
Why do I need to create an account to see results?
Two reasons: to unlock your calculation results, and to save calculations you want to revisit later. The account exists so you can pick up where you left off. We do not send marketing emails unless you subscribe to the newsletter, and we do not sell your data to suppliers or third parties.
Do these dropshipping formulas work for my niche?
The math is the same whether you sell fashion, electronics, home goods, or beauty products. Profit margin is profit margin. ROAS is ROAS. The calculators adapt to whatever numbers you enter, so they work for Shopify, WooCommerce, Etsy, Amazon, eBay, or any other e-commerce platform.
Can I use these tools before I have a store?
That is the best time to use them. Run the numbers before you order inventory, before you run ads, before you commit to a supplier. Find out if a product is viable on paper before you spend real money on stock or traffic.
Do I need to install anything?
No. ZeroNova runs entirely in your browser. Nothing to download, nothing to update, no browser extensions, no mobile app. It works on Chrome, Safari, Firefox, and Edge on desktop and mobile.
How accurate are the calculations?
Every formula uses standard e-commerce and direct-response math. The profit margin calculator accounts for product cost, shipping, platform fees, transaction fees, and ad CPA. The ROAS calculator uses the standard revenue/ad-spend formula. The break-even ROAS formula is sale-price divided by gross-margin per unit. These are the same formulas used by professional media buyers and e-commerce operators.
What is break-even ROAS?
Break-even ROAS is the minimum return on ad spend you need to not lose money. It is calculated as Sale Price divided by (Sale Price minus Product Cost minus Shipping). For example, if you sell a $30 product that costs $8 total (product + shipping), your break-even ROAS is 30/22 = 1.36x. Anything above that is profit; anything below means you are losing money.
What if I find a bug or want a new calculator?
Message us. We ship fast. Half the calculators on this site exist because someone asked for them. If you need a specific formula or tool that we do not have yet, tell us and we will build it.
