Days to Close

Time it the way it matters — month-end to the numbers landing in front of you, not the days your accountant spent working.

Benchmark: APQC open-standards measure 104615 puts the median monthly close at 8.0 days across 3,389 organizations. That times the accounting work; the bands here are ours, timed from month-end to the numbers in your hands. Why the close takes so long →

The calculators give you directional answers. The Financial Clarity Model gives you the complete picture, 12-month P&L, cash flow with three scenarios, and unit economics, all formula-linked from one inputs tab.

  • 12-month projected P&L, revenue, COGS, OpEx, EBITDA
  • Cash flow with Base / Upside / Stress scenarios
  • Dynamic runway counter updated month-by-month
  • Hiring plan with loaded costs and runway impact
  • Unit economics, LTV, CAC, payback, health indicators
  • One inputs tab drives everything else

This model is a planning framework and does not constitute financial, accounting, or tax advice. Consult a licensed professional for those services.
