Description
Here's the full long description, optimized for Eloquens search and written to convert browsers into downloaders:
Running out of cash is the single most common reason startups fail — not because the business idea was wrong, but because founders didn't see the timeline clearly enough, early enough, to act.
This free Startup Runway Calculator gives you an exact, data-driven answer to the question every founder eventually has to face: how many months do I have left before I run out of money?
Built by a Finance Officer working in credit control and cash flow management at a Fortune 500 multinational, this isn't a generic template pulled from a textbook — it's built using the same logic used to manage real cash positions in a professional finance environment, simplified into a tool any founder or small business owner can use in under five minutes.
What the calculator does:
Enter four numbers — your current cash balance, monthly revenue, monthly operating expenses, and your expected monthly revenue growth rate — and the model instantly calculates your monthly net burn, your static runway in months, and the exact calendar date your cash position is projected to hit zero.
Beyond the static number, the model also includes an 18-month forward projection that compounds both revenue growth and expense growth month over month — giving a far more realistic picture than the simple "cash ÷ burn" calculation most founders default to. Every month in the projection is colour-coded green or red, so you can see at a glance exactly when the cash position turns negative.
Why this matters for fundraising and planning:
Investors and advisors consistently ask founders the same question: "What's your runway?" Having a precise, defensible answer — backed by a model rather than a guess — signals financial discipline and makes investor conversations more credible. This tool gives you that answer instantly, along with the supporting 18-month detail to back it up if asked.
Who this is for:
Early-stage founders preparing for investor updates or fundraising conversations. Small business owners who want clarity on how long their current cash reserves will last. Finance leads and operators who need a quick, reliable way to communicate burn rate and runway to a founder, board, or leadership team. Anyone who wants to move from "I think we have a few months left" to a precise, calculated answer.
What's included:
A fully built Excel model with editable input cells (clearly marked), automatic calculations for net burn, runway, and zero-cash date, an 18-month projection table with growth-adjusted revenue and expenses, colour-coded visual cues for at-a-glance reading, and a built-in instructions section explaining exactly how to use and interpret every number.
No sign-up required beyond the download. No hidden cost. Built to be genuinely useful on its own — and if you need deeper tools afterward, an Accounts Receivable Aging Tracker is also available on this profile.
