Essential Micro-Business Utilities for Solopreneurs
No paywalls, zero signups, and client-side security. Model software spend, structure SaaS pricing, project burn down runway, and calculate true hourly freelance yield.
Free calculators for founders, freelancers and indie hackers
Foundery Tools is a small suite of practical calculators built for one-person businesses. Instead of a spreadsheet you have to maintain, each tool gives you a visual answer in seconds: whether your AI subscriptions pay for themselves, what your SaaS pricing tiers should look like, how many months of runway you really have, and what hourly rate covers your taxes, admin time and time off.
Every tool is privacy-first by design. There is no account, no tracking of your inputs, and no server calculation: type your numbers, see the result, export a summary card or share a configuration link if you want to. The suite also includes everyday calculators founders search for constantly: profit margin and markup, break-even point, MRR and churn, hourly-to-salary conversion, LTV versus CAC, discounts and salary raises.
Are Foundery Tools really free?
Yes. Every calculator is free, needs no signup, and runs entirely in your browser, so your numbers never leave your device.
Who are these tools for?
Solopreneurs, indie hackers, freelancers and micro-SaaS founders who need fast, honest numbers for pricing, runway, software spend and hourly rates.
