I built a privacy-first suite of 15 marketing & margin calculators (No signups, no data tracking)

Hey everyone,

Like most digital marketers, freelancers, and indie hackers here, I spend a lot of time calculating ROAS, e-commerce net profit margins, or checking CAC vs. LTV ratios.

Launched my first product on PH today — a free calculator hub for marketers and investors

Hey everyone launched FinCalcHub Marketing today after getting tired of bouncing between different sites for financial and marketing calculations. One for ROI, another for SIP, another for tax estimates.

It covers ROAS/ROI for marketers, SIP/compound interest/retirement for investors, tax and profit margin for business owners, plus a live crypto converter and an A/B test significance calculator. No signup, everything runs in your browser.
