Tip: Difficulty multiplies effective pages. Example: 1.2 makes a book count as 20% longer; 0.9 as 10% shorter.

Plan sorts by priority then order. Last item may be partial if time runs out.
Estimated Days per Book
Bars show estimated days per selected book within the period.
Formulas used
Let: D_total = days_between(start, end) inclusive R_w = rest days per week R_total ≈ round(D_total × R_w / 7) D_eff = max(0, D_total − R_total) speed = pages per hour hours = reading hours per day η = efficiency (0..1) Pages per day: P_day = speed × hours × η Total capacity (pages): P_cap = P_day × D_eff If using average book length L_avg (pages): Books_possible = floor(P_cap / L_avg) If using the book list (each book i has length L_i and difficulty k_i): L_i_adj = L_i × k_i Days_i = ceil(L_i_adj / P_day) Add books in priority order while Σ Days_i ≤ D_eff Last book may be partial if time remaining < Days_i
How to use this calculator
- Choose your start and end dates for the reading period.
- Enter daily hours, reading speed, efficiency, and rest days per week.
- Keep Use book list enabled and edit the example books, or turn it off and enter an average pages per book.
- Click Create plan to see capacity, books possible, the table of planned titles, and the chart.
- Adjust inputs until the plan feels realistic and sustainable.
- Export your plan as CSV or PDF for sharing or tracking.
Rest days are estimated proportionally. Difficulty scales a book’s effective length to reflect denser or lighter reading.
FAQs
Estimates rely on your inputs. Reading speed, efficiency, and difficulty can vary daily. Treat outputs as a planning baseline and iterate as you learn your actual pace.
It scales a book’s effective length. A difficulty of 1.2 counts the book as 20% longer than its page count; 0.9 counts it as 10% shorter.
They’re approximated proportionally by week across the period. If you want precise weekday exclusions, adjust dates or reduce efficiency to simulate interruptions.
Yes. The planner will mark the last title as partial if the remaining time cannot cover the full estimated days for that book.
Use your average pages per hour for similar material. Non-fiction with diagrams may slow reading; light fiction may increase it. Adjust after a few days of tracking.
Use the CSV and PDF buttons in the Summary card. CSV is great for spreadsheets; PDF bundles key metrics, the plan table, and the chart image.
