Startup Runway & Cash Burn Simulator

Project your cash position forward month by month and see the exact month you'd run out, or the month your growth catches up to your burn.

Reading This Tool

How To Use This Calculator

Enter your current cash, monthly expenses, current revenue, and how fast you expect revenue to grow.

The chart projects your cash balance forward 24 months and marks the exact month it would hit zero, if it does at all within that window. If the result shows under 6 months of runway, treat that as the trigger to raise, cut burn, or both, not a number to check in on passively next quarter.

Your Inputs

Expenses are held constant in this model. If you expect headcount or spend to scale alongside revenue, treat the death date below as optimistic.

This is a simplified, single-scenario projection: it assumes expenses stay flat and revenue compounds at a constant monthly rate. Real cash flow is lumpier than this, treat this as a directional read, not a bank-ready forecast. Our 13-week rolling forecasts are built from your actual reconciled ledger and updated monthly.

If that date is sooner than you'd like, let's fix the model together.
