1.5 hours short per night × 365 = 548 hours annual deficit. At 20% productivity drop per hour (conservative estimate) × 40/hour value: 4,380/year productivity loss. Long-term sleep debt also affects health spend, mistakes, injury risk.

Run it with sensible defaults

Using hours short per night of 1.5, productivity loss per hour short of 20%, your hourly value of 40, the calculation works out to 4,380.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Hours Short per Night, Productivity Loss per Hour Short, and Your Hourly Value — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

How the math works

Deficit × loss factor × value × 365. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Pricing your time honestly

Most people underprice their time because they see the hourly rate, not the fully-loaded cost of each hour (tax, benefits, overhead, opportunity). This tool pushes the rate up to the number that reflects real value — which changes the maths on a lot of "is it worth doing myself?" questions.

What this doesn't capture

Hour-for-money math misses the tasks you enjoy and the ones that build skill. The number is an efficient-markets view of your time; real decisions about what to do yourself vs outsource should also weigh what you learn and what you enjoy.
