How the trajectory gate works
This tool grades your AI spend against its annual budget by projecting where compounding month-over-month growth lands you. It reads the trend across 3 periods — not a single snapshot — then a gate that can only make the verdict worse.
The trajectory
When compounding month-over-month growth pushes projected annual spend more than 20% past budget, the verdict is forced to BLOWOUT AHEAD regardless of the score — today's headroom can't save a burn rate that's still climbing. The trajectory wins, not the current-month number.
Why: At $8K/mo four months in, the budget looks comfortable — but spend is compounding 18% every month. Projected across the remaining eight months, the year lands at about $166.7K against a $120K budget: 39% over, blowing out in month 11 of 12. The runaway-growth gate forces BLOWOUT AHEAD — the flat-looking current number was hiding the climb.
A single-period number lies when the trend is against you. The gate reads the trajectory and bumps the verdict one level worse — and names the one thing to fix first. Forecasts your own spend numbers deterministically and invents nothing. Not financial, accounting, or tax advice.
