30 pages/day × 300 pages/book × 50 years: 1,825 books read. 15 pages/day — still 912 books lifetime. Most people read 4-12 books/year; a modest 30 pages/day puts you in the top 5% of readers globally.
Run it with sensible defaults
Using pages per day of 30, pages per book of 300, years of 50, the calculation works out to 1825 books. 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 — Pages per Day, Pages per Book, and Years — 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
Simple multiplication. 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.
Related calculations worth running
Plans get firmer when you triangulate. Alongside this one, the language learning value calculator, the skill acquisition learning curve, and the habit streak value calculator tend to come up in the same conversations. Running two or three together exposes inconsistencies in any single assumption — which is usually where the useful insight lives.
