The number of months you can be wrong for

Runway is months, not money

A bank balance is not a plan. The figure that governs every decision in your first year is runway: how many months you can go on living if no money comes in. It is one division.

runway_months = cash_you_can_actually_spend / monthly_survival_cost

Both numbers are usually wrong in the same direction the first time somebody computes them, so do each deliberately.

The numerator: cash you can actually spend

Not net worth. Not the laptop’s resale value. Not money you have promised to a family obligation. Not a credit limit: borrowing extends the crisis rather than the runway, because it adds a fixed monthly cost to the denominator.

Subtract, before you start:

• Tax you already owe on income earned but not yet assessed. If you are setting aside nothing, you are spending the government’s share and will meet it later.
• Any deposit or advance you have taken for work not yet delivered. That money is a liability wearing the costume of cash.
• An emergency floor you refuse to touch: one month of survival cost is the usual minimum, because a broken laptop in month four otherwise ends the business.

The denominator: survival, not current spending

Write two columns. The first is what you spend now. The second is what you would spend in a bad month: rent or contribution to the household, food, utilities, transport, phone and internet, medicines and insurance premiums, loan repayments, and the small number of subscriptions the work cannot run without.

Add the costs that only appear once you are independent and which employees never see, because an employer was paying them:

• Health insurance, if your country ties it to employment.
• Your own pension or retirement contribution. Nobody is matching it now.
• Equipment replacement, amortised. A laptop that costs ₹90,000 and lasts three years is ₹2,500 a month whether or not you feel it that month.
• Software. Adobe’s all-apps plans (Creative Cloud Standard or Pro) cost about US$55 to US$70 a month on an annual plan in the US, and in India about ₹2,100 to ₹2,700 a month including GST, less under a first-year offer (checked October 2026; check adobe.com/in for today’s price). That is a real line in the denominator. The free path exists and is not a consolation prize: Photopea or GIMP and Krita for raster, Inkscape for vector, Scribus for layout, DaVinci Resolve for video and grading, Kdenlive or Shotcut for cutting, Blender for 3D and motion, Audacity for audio, and Google Fonts for typefaces you may legally embed and hand to a client. A first year run on these tools is a first year with roughly ₹25,000 to ₹33,000 more runway at the regular price.

What the answer means

Broadly, and from watching a lot of people do this:

• Under three months. Do not quit. Run the overlap for longer. Three months is not a runway, it is a countdown, and every pricing conversation you have on a countdown you will lose, because the client can hear it.
• Six months. Workable if you already have one or two clients booked. Six months is roughly one full sales cycle plus one payment cycle plus one recovery from a surprise.
• Twelve months. Comfortable, and long enough to make a positioning mistake, notice it, and correct it.

The reason short runway is expensive is not that you starve. It is that it makes you accept bad work at bad prices from bad clients, and each of those consumes the weeks you needed for finding good ones. Desperation is a pricing input and clients are good at detecting it.

The lag nobody budgets for

There is a gap between doing work and holding money, and in the first year it is longer than anyone expects. Add it up: two weeks to find the job, three weeks to do it, the client takes a week to approve, you invoice on net-30 terms, they pay on day 38 because their finance run is monthly, and the international transfer clears in three working days. That is roughly ten weeks from the day the client says yes to money in the account, and twelve if you count the fortnight it took to find them.

So the practical rule: your runway must cover your survival cost plus the length of your cash cycle, not just your survival cost. If you begin with six months of runway and a ten-week cycle, you effectively have about three and a half months of decision-making room.

Re-run it monthly, in five minutes

Runway is not a number you calculate once at the start. On the first of each month, write down two figures: cash you can spend, and the last three months’ average survival cost. Divide. Write the result in the same place every month.

Watching that number is different from watching your bank balance, because it automatically accounts for your spending drifting upward. A balance that has been flat for four months while your costs rose fifteen per cent is a runway that shrank, and the division shows it while the balance hides it.

When runway drops below three months, the correct response is not to work harder on the current job. It is to spend that week on pipeline, which is the one thing a busy month always crowds out, and the reason the empty month arrives.
