Free Startup Calculators for Founders
Startup calculators are free online tools that help founders track burn rate and runway, model equity dilution, analyse SaaS metrics, and plan unit economics — without needing a spreadsheet or a finance hire. The five tools cover the core metrics investors ask about: burn rate and runway (how many months until you need to raise), unit economics (LTV, CAC, and payback period), SaaS metrics (MRR, ARR, NRR, and Quick Ratio), equity dilution (what a funding round takes from founders' ownership), and break-even analysis (the revenue point at which the business covers its costs). Each tool delivers a clear number, a benchmark against typical funded startups, and specific guidance on what the result means. Unlike platforms that require a brokerage account or a Carta subscription, everything here is free, runs in your browser, and takes 30 seconds to use.

What you can do with these tools
- Track gross burn, net burn, and cash runway — see the exact month your cash runs out at current spend
- Calculate LTV, CAC, and payback period to know whether your unit economics are investor-grade
- Model MRR waterfall, ARR, NRR, and Quick Ratio — the four metrics every SaaS board deck covers
- See how much founder equity a funding round dilutes, including pre- and post-money valuation
- Find your break-even point, contribution margin, and pricing sensitivity before locking in a model
- Every result includes smart insights and benchmarks — not just a number, but what to do next
Startup & Business Intelligence — frequently asked questions
01Are these startup calculators free to use?
Yes. Every calculator is completely free with no sign-up, no trial, and no paywall on the results. Tools that Visible.vc, ICanPitch, and Founderpath charge for — burn rate, equity dilution, SaaS metrics, and unit economics — are free here without an account.
02What is a startup burn rate calculator?
A burn rate calculator shows how fast your startup spends cash and calculates runway — the months of cash left at current burn. Gross burn is total monthly spend; net burn subtracts revenue. Runway below 6 months is critical; 12–18 months is healthy for a pre-Series A startup.
03What is a good runway before raising a funding round?
Most investors expect 12–18 months of runway when you start a fundraise, since a typical round takes 3–6 months to close. Starting with less than 12 months is a weak negotiating position. Use the burn rate calculator to find your runway and start raising at least 6 months ahead.
04What is a good LTV:CAC ratio for a startup?
A ratio of 3:1 or higher is the standard benchmark — each customer generates at least 3 times what it cost to acquire them. Below 1:1 means you lose money on every customer. A payback period under 12 months is healthy for SaaS; under 6 months is excellent.
05What SaaS metrics do investors look at?
Investors focus on MRR and ARR (revenue scale), NRR or Net Revenue Retention (expansion vs. churn), Quick Ratio (growth efficiency), and MRR churn rate. The SaaS metrics calculator produces all four — the same figures that appear in Series A and B board decks and data rooms.
06How accurate are the results?
Very accurate — formulas are verified against investor and accountant benchmarks and covered by automated tests. Results depend entirely on your inputs; use real figures for reliable output. These are planning estimates, not audited financials.
07Are these free alternatives to Visible.vc or ICanPitch startup calculators?
Yes. Calcrux covers the same burn rate, equity dilution, SaaS metrics, and unit economics calculations that Visible.vc, ICanPitch, and Founderpath provide — completely free, no account required. It works for founders in any country and supports multiple currencies.
08Can I use these tools outside the US, in my own currency?
Yes. The calculators work for founders in any country and adapt to your currency and region automatically, including USD, GBP, EUR, INR, and more. You can switch region and currency at any time and every figure reformats to match.
09How do I find the right calculator for my situation?
Browse the three groups on this page: Startup Finance for burn rate and unit economics, Funding & Equity for dilution modeling, and Strategic Planning for break-even and pricing decisions. Each tool page also links to the most complementary calculators so you can move between them in a few clicks.
10Do I need to understand finance or equity terms to use these?
No. Each calculator explains every input in plain language and interprets the result for you, with warnings and insights that flag things like a short runway or unhealthy LTV:CAC ratio. A first-time founder gets a clear, actionable answer in under a minute.
