What Is True Cash Position?
Your bank balance is not the amount of money you have available. It includes cash that is already committed to obligations you cannot avoid. True cash position strips those commitments away to show what you can actually use for operational decisions.
The problem with bank balance
You check your bank account and see $680,000. You feel comfortable. You open a spreadsheet, divide by your monthly burn, and the number says you have over a year of runway. But that number is misleading, because the bank balance includes money that is already spoken for.
Tax payments due next quarter are sitting in your account but belong to the government. Revenue you collected from annual contracts has not been earned yet; if you fail to deliver, it gets refunded. Payroll commitments for the next two pay cycles are technically in the bank but will leave within weeks. Vendor invoices you have approved but not yet paid are claims against your cash that simply have not cleared.
None of that cash is available for operational decisions. Treating it as available is the financial equivalent of counting the money in your wallet while ignoring the bills in your mailbox. Every finance team that has been surprised by a cash crunch can trace the surprise back to this gap between the balance on screen and the balance they could actually use.
Defining true cash position
True cash position is a straightforward subtraction. You start with the bank balance and remove every dollar that is already committed to a specific obligation. What remains is the cash you can genuinely allocate.
True Cash Position = Bank Balance
minus Tax Obligations (next 90 days)
minus Deferred Revenue
minus Committed Payroll (beyond standard monthly burn)
minus Outstanding Vendor Commitments
Consider a concrete example. A company has $680,000 in the bank. Their upcoming quarterly tax payment is $74,000. They collected $122,000 in annual prepayments for services not yet delivered. They have $98,000 in payroll commitments beyond what would normally appear in a monthly burn figure, including severance obligations and contractor invoices already approved. They owe $0 in outstanding vendor commitments because they pay vendors on receipt.
True cash position: $680,000 minus $74,000 minus $122,000 minus $98,000 = $386,000. That is 43% less than the bank balance. The number that felt comfortable is now a number that demands attention. RunwayCal surfaces this figure automatically on Mission Control so finance teams never have to calculate it by hand.
Why the gap matters
In the example above, bank balance runway says 12.4 months. True cash runway says 5.2 months. That difference is not a rounding error. It is the difference between a company that feels comfortable delaying fundraising and a company that should be talking to investors right now.
The gap changes hiring decisions. At 12 months of runway, adding two engineers feels reasonable. At 5 months, it is reckless. The gap changes fundraising timing. At 12 months, you have the luxury of being selective. At 5 months, you are approaching the zone where investors sense desperation and terms deteriorate. The gap changes board conversations. Presenting 12 months of runway creates confidence. Presenting 5 months creates urgency. Both of those reactions are appropriate for their respective numbers, which is exactly why using the wrong number is dangerous.
Companies that operate on bank balance runway consistently make decisions that are too aggressive for their actual position. They hire when they should hold. They expand when they should focus. They delay fundraising when they should start. The pattern is predictable because the input is consistently wrong. Understanding how runway calculation works at a deeper level starts with getting the cash input right.
How to calculate yours
Step 1: Record your current bank balance
Use the actual cleared balance, not the available balance that includes pending deposits. If you have multiple accounts, sum them. Include savings accounts and money market accounts. Exclude credit lines and undrawn facilities; those are options, not cash.
Step 2: Itemize tax obligations for the next 90 days
Quarterly estimated payments, payroll taxes not yet remitted, sales tax collected but not yet filed, and any other tax liabilities that will come due. If you are uncertain about the exact amount, use the higher estimate. Tax obligations are not negotiable deadlines.
Step 3: Sum your deferred revenue
This is money customers have paid you for services or products you have not yet delivered. Annual prepayments are the most common source. If a customer paid $24,000 for a year of service and you have delivered four months, $16,000 of that payment is deferred revenue. It is in your bank account but it is not yours to spend freely.
Step 4: Add committed payroll beyond monthly burn
Your standard monthly burn already accounts for regular payroll. This step captures the extras: severance packages for planned departures, contractor invoices approved but not yet paid, bonuses accrued but not yet disbursed, and any payroll-adjacent obligations (benefits arrears, retirement contributions due) that sit outside the recurring monthly number.
Step 5: Subtract everything from bank balance
The result is your true cash position. If you want to go further, add outstanding vendor commitments: invoices received but not yet paid, purchase orders issued, and signed contracts with payment milestones approaching. The more thorough you are, the more accurate the number. A runway calculator that uses this adjusted figure will give you a far more realistic picture of your operating timeline.
What to do with this number
The goal is not to replace bank balance runway with true cash runway. Both numbers are useful. The goal is to use each one for the right purpose.
Use bank balance runway as an upper bound. It represents the theoretical maximum time you could operate if every obligation disappeared and every dollar in the account were available. It is useful for quick comparisons and for communicating the broadest possible timeline to people who do not need the operational detail.
Use true cash runway for every operational decision. Hiring, vendor commitments, expansion plans, and fundraising timing should all be evaluated against the true number. This is the figure that determines whether you can actually afford the next commitment, not just on paper, but in reality.
Include both figures in every board deck. Presenting them side by side shows that you understand the distinction and are making decisions based on the more conservative number. This builds credibility with investors, who are accustomed to seeing companies operate on optimistic assumptions. RunwayCal's true cash position tracking maintains both figures automatically and updates them as obligations change.
Update the calculation monthly, or more frequently if your obligation profile is changing. Tax deadlines, large customer prepayments, and new contracts all shift the true cash number. The bank balance will look steady while the true position fluctuates underneath. Catching those fluctuations early is the difference between proactive management and reactive scrambling.
