Debt (h)

About this calculator

Use this calculator for debt = (hours needed per night − hours actually slept) × number of days. A negative result means you slept more than the need you typed. This is a napkin total, not adenosine kinetics, and you cannot bank sleep like cash. Epworth is a different sleepiness page.

Need (h / night): Hours you think you need.

Got (h / night): Hours you actually slept.

Days: How many nights of that pattern.

Debt (h): Cumulative hours of debt (or surplus if negative).
