Tools you'd actually use.
Free, no signup, instant results. Every number is computed in your browser from what you typed. When you want the product itself checked — a Worth Testing / Caution / Skip verdict with the evidence behind it, an AI video ad rendered from it, and a downloadable landing page built around it — that's the paid version.
Dropshipping profit margin calculator
Cost + shipping + ad spend + retail price → real net margin and breakeven. Test a product before you list it.
ROAS calculator
The ROAS you actually need, not the one the ad manager shows. Breakeven ROAS, profit ROAS, ACOS and net profit after COGS.
Pricing strategy calculator
Keystone, 3x, charm pricing or target margin — five candidate retail prices side by side, with the net margin each one really leaves.
Shipping cost calculator
Volumetric vs actual weight, billable weight, cost per unit, and exactly what free shipping takes out of the order.
Niche scorecard
Score a niche 0–100 across margin, order value, competition, repeat purchase, seasonality, shipping and ad risk. The weighting is printed on the page.
Business name generator
24 store names from one keyword in four styles — modern, playful, premium, descriptive. Deterministic, offline, copy in one click.
Post engagement calculator
Engagement rate by follower and by reach, plus the benchmark band for that follower tier. Useful before you pay a creator.
Shopify product spy
Paste any Shopify store URL. See every variant, price, and image. Built on Shopify's public product feed.
The calculators tell you if the numbers work. Dropship Spy tells you if the product does.
Paste a product and it analyses current demand, sourcing, pricing, competition, buyer-intent and risk data, then returns a verdict with a private evidence trail of source receipts. From there it writes and renders a vertical video ad, and generates a conversion-optimised landing page you download as one self-contained HTML file — no branding, no lock-in.
