Startup Calc: Founder Tools

Model startup decisions faster: runway, valuation, dilution, SaaS metrics, CAC, LTV, AI pricing, product ROI, and software costs.

Startup Calc is a startup calculator for founders, investors, product managers, engineering leaders, SaaS operators, and AI product teams who need faster answers to important business decisions.

Model fundraising, valuation, dilution, runway, burn, SaaS metrics, product ROI, AI pricing, software costs, hiring plans, and engineering tradeoffs in one clean workspace.

Instead of bouncing between spreadsheets, notes, and one-off web tools, Startup Calc gives you fast, clear calculators built for real operator workflows.

Use Startup Calc to answer questions like:

Can we afford this hire? How much runway do we have? What happens after this fundraising round? How does dilution affect ownership? What is our CAC, LTV, MRR, or ARR? How much will API or AI token usage cost? Is this product feature worth building? What pricing model gives us better margins?
