What Burnout Monitor Calculates

Your effective hourly rate after sleep-loss cognitive penalty is subtracted from tomorrow.

Burnout Monitor answers one question: if you stay up to work tonight, is the net the next 48 hours actually positive?

Willpower battery reads battery unmeasured. Every hour worked past the sleep-debt threshold comes out of tomorrow at a worse ratio. Burnout Monitor takes tonight's sleep, tonight's extra hours, and hourly rate. It returns gross tonight, tomorrow's cognitive loss, and net. Net often drops below zero.

▸ Deterministic Formula
Effective Rate = Hourly × Multiplier
Tomorrow Loss = Hourly × 8 × (1 − Multiplier)
Net = (Hourly × Extra Hours × Multiplier) − Tomorrow Loss
Multiplier: 8h=1.00, 7h=0.95, 6h=0.85, 5h=0.72, 4h=0.60, 3h=0.48, <3h=0.35
▸ Logical Gates
  1. Enter tonight's realistic sleep hours, not the target.
  2. Enter extra hours you would add by staying up.
  3. Enter the hourly rate those extra hours actually produce.
  4. If net is negative or tomorrow is deep-work, stop and sleep.
  5. If crunching multiple nights, discount the single-night result further.

▸ Key Specs

  • ▸ Cognitive multiplier by sleep: 8h = 100%, 7h = 95%, 6h = 85%, 5h = 72%, 4h = 60%, 3h = 48%, under 3h = 35%. Battery now: battery unmeasured.
  • ▸ Effective rate tonight = hourly × multiplier. Extra hours pay less than the rate on paper.
  • ▸ Tomorrow's loss = hourly × 8 × (1 − multiplier). Tomorrow runs at the degraded rate.
  • ▸ Net = gross tonight − tomorrow's loss. Usually negative under 5h sleep.
  • ▸ Multipliers are directional — individual variance is wide.
  • ▸ Compounds on consecutive nights. Two nights of 5h sleep is worse than the single-night figure predicts.

▸ Worked Examples

  • 5h sleep, 3 extra hours tonight, $30/hr
    Multiplier 72% → effective $21.60. Gross tonight 3 × $21.60 = $64.80. Tomorrow: 8h × $30 × 0.28 = $67.20 loss. Net: −$2.40. Staying up cost money. Battery: battery unmeasured.
  • 7h sleep, 2 extra hours, $40/hr
    Multiplier 95% → effective $38. Gross tonight $76. Tomorrow: 8h × $40 × 0.05 = $16 loss. Net: +$60. Worth it.
  • 4h sleep, 4 extra hours, $25/hr
    Multiplier 60% → effective $15. Gross tonight $60. Tomorrow: 8h × $25 × 0.40 = $80 loss. Net: −$20. Strictly worse than sleeping.

When to use which tool

▸ Operational Thresholds
  • CYAN · STABLE — 7+ hours sleep, net positive after tomorrow loss — extra hours pay off.
  • GOLD · GUARDED — 5-6 hours sleep, small net gain — break-even zone, diminishing returns.
  • MAGENTA · CRITICAL — Under 5 hours or negative net — strictly worse than sleeping, stop working now.

Frequently asked questions

› Are the sleep multipliers scientifically precise?

They approximate the consensus research on cognitive performance under sleep restriction (psychomotor vigilance, attention, decision quality). Individual variance is large — treat the number as directional.

› What about caffeine?

Caffeine masks subjective fatigue without restoring cognitive function. The multipliers apply regardless of stimulant use; you just don't feel as bad.

› Does it work for creative vs. analytical work?

Creative work often degrades harder than analytical — novel-problem-solving is more sleep-sensitive than routine execution. If your extra hours are deep work, the real multiplier may be lower than the table shows.

› How should I use a decision framework in real life? How-to

Use a decision framework to expose the tradeoff, not to outsource the decision. Write down the inputs, compare the output with your constraints, then ask what would change the answer. The strongest use is scenario testing: base case, conservative case, and failure case.

› Is this financial, legal, or tax advice? Trust & accuracy

No, this is not legal, financial, tax, medical, or professional advice unless the page explicitly says that use case is supported. It organizes assumptions so you can inspect them. Verify high-stakes choices with qualified people who can review facts, contracts, regulations, and downside risk.
