▸ METHODOLOGY
Runway = Cash ÷ (Burn − Revenue). The Zero Date is projected from today using 30-day months. Crisis mode zeroes revenue to model the worst-case shock. Inputs persist locally.

How to use

  1. Enter your current Cash Balance.
  2. Enter your total Monthly Burn (all outflows).
  3. Enter your Monthly Revenue (all inflows).
  4. Runway = Cash ÷ (Burn − Revenue). Enable Crisis to reduce revenue to $0.

Examples

$250k cash, $65k burn, $22k revenue
Net burn $43k/month → ~5.8 months runway. Zero date roughly 6 months out.
Crisis mode on same inputs
Revenue drops to $0 → runway shortens to ~3.8 months (250k ÷ 65k).

Before you act on the result

Finance tools depend on assumptions about income, expenses, time, rates, and behavior. They are planning aids, not investment, tax, legal, or credit advice.

Run a conservative version and a stress version before relying on a single number.

Frequently asked questions

› What counts as burn?

Every outflow: salaries, rent, infrastructure, marketing, taxes, contractors. If it leaves the bank each month, include it.

The calculator shows an Indefinite status. No runway zero exists at current pace.

› Is my data saved? Trust & accuracy

Yes — all inputs persist to localStorage on this device and nowhere else.
