Startup Runway Calculator
Calculate startup runway from cash, revenue, monthly expenses and growth assumptions. Estimate simple and projected runway in months.
Startup runway is the number of months a company can keep operating before its cash balance reaches zero. This calculator estimates runway from cash in bank, monthly revenue and monthly expenses. It also lets you add monthly revenue and expense growth assumptions, which gives a more useful projected runway than a flat burn-rate calculation.

Startup Runway Calculator क्यों उपयोग करें
Runway is one of the most important operating metrics for founders. It determines hiring pace, fundraising urgency and how aggressively the company can spend on growth. A simple cash divided by net burn calculation is useful, but it misses improving revenue or rising costs. This calculator shows both simple runway and projected runway so founders can sanity-check their plan.

अक्सर पूछे जाने वाले प्रश्न
What is startup runway?
Startup runway is the estimated time a company can operate before it runs out of cash, usually measured in months.
What is net burn?
Net burn is monthly expenses minus monthly revenue. If revenue is higher than expenses, the company is not burning cash operationally.
How much runway should a startup keep?
Many founders aim for at least 12 to 18 months after a funding round and start fundraising before runway falls below 6 to 9 months.
Why does projected runway differ from simple runway?
Projected runway changes monthly revenue and expenses over time, while simple runway assumes today's net burn stays constant.
अंतिम बात
Use the startup runway calculator every month during operating reviews. A clean runway view helps founders decide when to cut burn, accelerate revenue, delay hiring or start fundraising.
