The information provided by CalculatorTools (“we,” “us,” or “our”) on https://digistoremb.com (the “Site”) is for general informational and educational purposes only. By using our website and its suite of tools—including the Amazon Seller Fees Calculator, Shopify Profit Calculator, Ecommerce Profit Margin Calculator, and Amazon Sales Estimator—you acknowledge and agree to the terms laid out in this Disclaimer.
1. General Information Disclaimer
All information on the Site is provided in good faith. However, we make no representation or warranty of any kind, express or implied, regarding the accuracy, adequacy, validity, reliability, availability, or completeness of any information on the Site. Your use of the Site and your reliance on any information on the Site is solely at your own risk.
2. Financial Tools & Accuracy Disclaimer
Our website provides automated calculators designed to assist e-commerce sellers, dropshippers, and entrepreneurs in estimating costs and profits. While we strive to keep our algorithms updated with the latest data, the results provided by CalculatorTools should be treated as **estimates only** and not as guaranteed financial facts. Here is why:
2.1. Amazon Fees Volatility
Amazon frequently updates its fee structure for FBA (Fulfillment by Amazon) and Referral Fees. These changes can occur without prior notice and may vary based on product category, dimensions, weight tiers, and seasonality (e.g., Q4 storage fees). While our Amazon Seller Fees Calculator uses the most recent standard rate cards available to us, we cannot guarantee that the output will match Amazon’s final charge down to the penny. Variables such as “Dimensional Weight” versus “Actual Weight” can significantly impact the final fee, and Amazon’s warehouse measurement scans may differ from your own measurements.
2.2. Shopify & Third-Party Fees
Our Shopify Profit Calculator assumes standard transaction fees based on the plan you select (e.g., 2.9% + 30¢). However, your actual costs may vary due to:
- Currency conversion fees (if selling internationally).
- Additional fees charged by third-party payment gateways like PayPal or Stripe.
- App subscription costs and variable marketing costs (CPA).
Therefore, CalculatorTools cannot be held liable for any discrepancies between our estimated profit margins and your actual bank deposits.
2.3. Sales Estimations
The Amazon Sales Estimator tool provides data based on historical Best Sellers Rank (BSR) trends. Amazon does not publicly release exact sales volume data. Consequently, our tool uses a proprietary algorithm to simulate potential sales volume. This data is for research and validation purposes only. You should never make large inventory purchasing decisions based solely on the output of this or any other estimation tool.
3. Not Professional Financial Advice
The Site does not contain professional financial, legal, or accounting advice. The e-commerce and business information is provided for general educational and informational purposes only and is not a substitute for professional advice. Accordingly, before taking any actions based upon such information, we encourage you to consult with the appropriate professionals (accountants, tax advisors, or business consultants).
THE USE OR RELIANCE OF ANY INFORMATION CONTAINED ON THE SITE IS SOLELY AT YOUR OWN RISK. We are not responsible for any financial losses, business failures, or unsold inventory resulting from the use of our calculators.
4. External Links Disclaimer
The Site may contain (or you may be sent through the Site to) links to other websites or content belonging to or originating from third parties or links to websites and features in banners or other advertising. Such external links are not investigated, monitored, or checked for accuracy, adequacy, validity, reliability, availability, or completeness by us.
For example, we may link to Amazon Seller Central or Shopify’s pricing pages for reference. We do not warrant, endorse, guarantee, or assume responsibility for the accuracy or reliability of any information offered by third-party websites linked through the Site.
5. Affiliates Disclaimer
The Site may contain links to affiliate websites, and we receive an affiliate commission for any purchases made by you on the affiliate website using such links. This helps keep our tools free for everyone. Our editorial content and tool accuracy are not influenced by these partnerships.
6. “As-Is” and “As-Available” Disclaimer
The tools and content on CalculatorTools are provided on an “as-is” and “as-available” basis. We do not warrant that the site will function uninterrupted, error-free, or that any defects will be corrected. We do not guarantee that the results obtained from the use of the tools will be accurate or reliable.
7. Limitation of Liability
In no event shall CalculatorTools, nor its directors, employees, partners, agents, suppliers, or affiliates, be liable for any indirect, incidental, special, consequential, or punitive damages, including without limitation, loss of profits, data, use, goodwill, or other intangible losses, resulting from (i) your access to or use of or inability to access or use the Service; (ii) any conduct or content of any third party on the Service; (iii) any content obtained from the Service; and (iv) unauthorized access, use or alteration of your transmissions or content, whether based on warranty, contract, tort (including negligence) or any other legal theory, whether or not we have been informed of the possibility of such damage.
