Runway inputs
- Projected runway
- 7.7 months
- Monthly net cash flows; surplus retained. Projection capped at 120 months.
- Simple runway
- 7.1 months
- Net burn
- ₹7,00,000
- Gross burn
- ₹12,00,000
మీ లెక్కలు ఏమి చెబుతున్నాయి
You have about 7.7 months of cash left.
That's under the 18-month rule of thumb for comfortable runway; start fundraising or cutting burn now.
Your growth rates add 0.6 months of runway versus flat numbers.
With no growth you'd have 7.1 months; with 5.0% monthly revenue growth and 1.0% monthly expense growth you get 7.7.
Cutting monthly expenses by 10% adds about 2.3 months of runway.
That's ₹1,20,000 less spend each month, with the same growth rates.
You need ₹7,00,000 more revenue a month to break even.
That's 140% more than today's ₹5,00,000, at current expenses.

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 ఎందుకు ఉపయోగించాలి
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.
ఒక్క చూపులో ప్రయోజనాలు
Simple and projected runway
Compare the basic cash divided by net burn view with a month-by-month projection.
Gross and net burn visibility
Separate monthly expenses from the net cash loss after revenue.
Useful for fundraising timing
Estimate how many months remain before a bridge round or full fundraise is needed.

Use simple runway as a baseline and projected runway for planning.
ఉదాహరణ
Seed-stage runway example
A startup has ₹50 lakh in the bank, ₹5 lakh of monthly revenue and ₹12 lakh of monthly expenses. Net burn = ₹12 lakh − ₹5 lakh = ₹7 lakh. Simple runway = ₹50 lakh ÷ ₹7 lakh ≈ 7.1 months. If revenue grows 8% a month and expenses 2% a month, the month-by-month projection stretches runway to about 8.0 months.
- Gross burn
- ₹12 lakh a month
- Net burn
- ₹7 lakh a month
- Simple runway
- About 7.1 months
- Projected runway (8% revenue, 2% expense growth)
- About 8.0 months
Even fast revenue growth buys less than a month here, because burn is large relative to revenue. A raise or cost cut needs to start now, not after growth shows up.
ఇది ఎలా లెక్కించబడుతుంది
Net burn = monthly expenses − monthly revenue and gross burn is simply monthly expenses. Simple runway = cash ÷ net burn; if net burn is zero or negative, simple runway has no end, and with no cash it's zero.
Projected runway steps through months. Each month, that month's burn (expenses − revenue) is subtracted from cash, then revenue grows by (1 + revenue growth %) and expenses by (1 + expense growth %) for the next month. Surpluses in profitable months are added back to cash.
When a month's burn is larger than the cash left, the calculator counts only the fraction remaining cash ÷ that month's burn, so runway can end part-way through a month. The projection stops at 120 months; if cash is still left then, the result shows 120+ rather than an exact figure.
అనుమానాలు మరియు పరిమితులు
- The projection runs at most 120 months; 120+ means cash remains at the horizon, not that runway is infinite.
- Each month adds revenue and subtracts expenses, retaining cash surpluses; cash exhaustion part-way through the final month is interpolated using that month's burn.
- Revenue and expenses grow at constant monthly rates. Revenue must represent cash collected, not merely invoiced revenue.
- Projection is independent of today's net burn: a currently profitable business can exhaust cash later if expenses grow faster.
- Debt repayments, one-time fundraises and tax timing are not separately modelled.
తరచుగా అడిగే ప్రశ్నలు
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.
What's the difference between gross burn and net burn?
Gross burn is everything you spend in a month. Net burn is what's left after revenue comes in. Net burn sets runway, but gross burn shows how much you'd need to cut if revenue dipped or a large customer left.
Can a profitable startup still run out of cash in the projection?
Yes. If expenses grow faster than revenue, a month-one surplus can turn into a deficit later and eventually drain the bank balance. The projection captures this; simple runway, which only looks at today's burn, doesn't.
What should count as cash in bank?
Use money you can actually spend on operations: bank balances and liquid deposits. Leave out committed but undisbursed funding, receivables you haven't collected and money already earmarked for loan repayments or tax.
చివరి మాట
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.
