Business & Startup Calculators
Model unit economics, runway, pricing, and growth metrics for startups and small businesses. These tools help founders and operators forecast revenue, costs, and key SaaS metrics.
Startup and small-business decisions hinge on numbers: runway, margins, pricing, and customer economics. These free calculators give fast answers without building a spreadsheet from scratch.
Runway and burn rate
Burn rate measures how fast a company spends cash. Runway is months until cash runs out at current burn. Founders track net burn (revenue minus expenses) monthly and after fundraising.
Use runway calculators before hiring waves or capital raises to see how long current cash lasts under base and stress scenarios.
Unit economics and margins
CAC (customer acquisition cost) and LTV (lifetime value) define whether growth is sustainable. Margin and markup calculators clarify pricing after costs.
Break-even analysis shows the volume or revenue needed to cover fixed and variable costs—essential for new product lines and retail expansion.
Growth and operational metrics
Conversion rate, ROAS, and commission calculators help marketing and sales teams optimize spend. Churn and retention metrics matter for subscription businesses.
Combine multiple tools: e.g. estimate marketing ROAS, then feed customer volume into break-even and runway models.
