Scale, Keep, or Cut?

The marginal hourly of the next hour vs your honest opportunity cost. Above the line → grow. On it → keep. Below it → cut.

Home › Calculators › Scale or Stop

Enter the payout, costs and minutes the next hour would really take, plus what that hour is worth to you elsewhere. Then press Calculate.
From the book — Chapter 7. Marginal hourly = (payout − costs) ÷ (minutes ÷ 60). Compare to the honest value of the same hour spent otherwise — a second job, rest, family, study. Above → grow. Near → keep. Well below → cut.

You choose the opportunity cost — money, sleep, and life all count. Figures stay in your browser.
