Definition

Cash balance is the amount of cash (and often cash equivalents) available at a point in time. It is the starting point for runway planning.

Example

If you have $1.2M in the bank and $200k restricted cash, available cash balance is $1.0M.

How to use it

  • Use cash balance with net burn to estimate runway.
  • Separate restricted cash from available operating cash for planning.
  • Track cash balance alongside collection timing and upcoming obligations.
  • Reconcile bank balance to ledger monthly to catch timing issues early.

Common mistakes

  • Assuming all cash is available (ignoring restricted or pledged cash).
  • Using a static balance without forecasting inflows and outflows.
  • Ignoring upcoming debt payments or vendor prepayments that reduce usable cash.

Measured as

Measure Cash Balance with the same date, unit basis, and accounting or policy definitions used in the rest of your model.

Misused when

  • Assuming all cash is available (ignoring restricted or pledged cash).
  • Using a static balance without forecasting inflows and outflows.
  • Ignoring upcoming debt payments or vendor prepayments that reduce usable cash.

Operator takeaway

  • Use cash balance with net burn to estimate runway.
  • Separate restricted cash from available operating cash for planning.
  • Track cash balance alongside collection timing and upcoming obligations.
  • Tie Cash Balance to the same balance-sheet date, scenario, and decision memo you are using elsewhere in the model.
  • Document which claims, costs, or adjustments your team includes before comparing numbers across forecasts, covenants, or valuation work.
