Most runway calculators get India wrong

Global tools (Causal, Mosaic, Founderpath) compute runway as cash ÷ burn. In India that under-states your real cash by 5–18% because GST input credit and customer TDS aren't in your bank balance yet — but they will be. This calculator includes them.

How to calculate startup runway (India formula)

Runway (months) =
  ( Cash in bank
    + GST credit receivable
    + TDS receivable
    + Collectible AR )
  ÷ ( Monthly burn  −  Monthly revenue )

Why each adjustment matters:

  • GST input credit — every expense you pay reclaims 18% GST. For a startup spending ₹10L/month, ~₹1.8L is locked in your GSTR-2B as recoverable credit. Treat it as cash.
  • TDS receivable — Indian B2B customers withhold 1–10% TDS on your invoices. That money is yours; it shows up as Form 26AS.
  • Collectible AR — outstanding invoices with a clear payment date. Use only what you'll actually collect this quarter.
  • Monthly burn − revenue — net burn, not gross. A profitable month means infinite runway.
