About Merii
Why this site exists
Most dropshipping advice online covers marketing, product research, and ad creative — and almost none of it covers the plain arithmetic that decides whether a store actually keeps any of the money it makes. New sellers are left pricing products by copying a competitor, guessing at a round number, or building a spreadsheet from scratch every time they want to check a margin.
Merii is a small, focused set of calculators and generators built to close that gap: profit margin, pricing, break-even, ad spend, and payment fees on one side, and quick naming and slogan tools on the other. Every tool runs instantly in your browser, shows the formula behind its numbers, and is written to be understood by someone pricing their very first product — not just someone who already has an accounting background.
Who's behind this site
[Add a few honest sentences here about yourself: your name, your background with e-commerce or dropshipping, and why you decided to build these specific tools. A short, real story here does more for both reader trust and AdSense approval than any amount of extra copy elsewhere on the site — reviewers and readers alike are specifically checking whether a real, identifiable person stands behind the content.]
[Optional: add a photo, a link to your LinkedIn or a social profile, and the city or country you operate from. None of this is required, but sites that include it are generally viewed as more trustworthy by both readers and automated quality reviews.]
How we keep the tools accurate
Every formula on this site — profit margin, markup, break-even order count, break-even ROAS, and payment-fee math — uses standard, widely used business formulas, laid out in plain language next to each calculator so you can check the logic yourself rather than trust a black box. Where a number genuinely varies by provider or country, such as payment processing rates, we say so directly instead of quoting a figure that might already be out of date for your account.
If you ever spot a calculation that looks wrong, please use the Contact page — corrections are welcome and get reviewed directly.
What this site is not
These tools are calculators, not consultants. They give you a fast, formula-based estimate to work from, not personalized financial, legal, tax, or accounting advice. For decisions that meaningfully affect your business or your taxes, it's worth checking the numbers with a qualified professional in your country. See our full Disclaimer for details.
