Formula used

  • Reading hours = (Sources × Pages per source) ÷ Pages per hour
  • Per-source workflow hours = Sources × (Search + Notes + Extraction + Appraisal minutes) ÷ 60
  • Core work = Reading + Per-source workflow + (Synthesis + Outline + Draft + Revision + Formatting + Meetings)
  • Break hours = Core work × Break %
  • Buffer hours = (Core work + Break hours) × Buffer %
  • Total before efficiency = Core work + Break hours + Buffer hours
  • Final total = Total before efficiency ÷ (Efficiency % ÷ 100)
  • Required hours/day = Final total ÷ Days available

How to use this calculator

  1. Enter how many sources you will review and average pages per source.
  2. Set your reading speed in pages per hour for the same difficulty level.
  3. Adjust per-source minutes for searching, notes, extraction, and appraisal.
  4. Add project-level hours for synthesis, outlining, drafting, revising, and formatting.
  5. Use breaks and buffer to match your real workday conditions.
  6. Set focus efficiency to reflect interruptions or strong focus sessions.
  7. Add days available and hours/day to see if your plan is feasible.
  8. Click Calculate, then export your estimate as CSV or PDF.

Translate sources into hours

Start with volume. If you plan 12 sources at 18 pages each, that is 216 pages. At 24 pages per hour, reading time becomes 9.0 hours. Add per-source setup, searching, and extraction: for example 10 + 8 + 12 minutes equals 30 minutes per source, or 6.0 hours across 12 sources. This calculator totals those components so the estimate stays auditable. Track assumptions and refine them after a short pilot session.

Calibrate speed and depth

Reading speed changes with complexity. A dense methods paper may drop from 30 to 15 pages per hour, doubling time. Use the "notes and appraisal" minutes to represent deeper evaluation, such as coding variables or rating quality. If your average appraisal is 20 minutes per source, 12 sources add 4.0 hours. Small adjustments here often matter more than tweaking breaks by a few minutes. Prefer median pace, not your best day.

Account for cognitive overhead

Research is not only reading. Synthesis, outlining, drafting, revising, and formatting can exceed intake time. A practical split is 40% intake, 60% production. For a 20-hour project, that implies 12 hours for writing and edits. Include meeting time, supervisor feedback, and citation cleanup as project hours. The calculator keeps these as separate line items so you can negotiate scope without arguing about speed. Add versioning and secure file organization time too.

Use buffers and efficiency correctly

Buffers protect deadlines. A 15% buffer on 22 core hours adds 3.3 hours. Efficiency models interruptions: at 80% focus, divide by 0.80, turning 25.3 hours into 31.6 hours. This is why "I have six hours" can produce four effective hours. Pair buffer and efficiency with breaks to avoid overly optimistic plans that collapse during heavy weeks or exam periods. Recheck weekly and adjust before drift grows.

Turn totals into a weekly schedule

Convert totals into daily targets with days available. If final effort is 31.6 hours and you have 8 days, you need 3.95 hours per day. Compare that with your cap, like 3 hours per day, to spot a gap early. Reduce sources, shorten pages, or increase speed only when justified. The plan becomes actionable when you block time: two 120-minute sessions plus one 30-minute review. Protect one catch-up day.


FAQs

What should I count as a source?

Count any distinct item you must locate, read, and cite: a paper, chapter, report section, dataset documentation, or interview transcript. If one report has three separate relevant sections, treat them as three sources for better accuracy.

How do I pick a realistic pages‑per‑hour rate?

Time a 10-page sample at normal focus, including scrolling and quick re-reads. Convert minutes to pages per hour and use the median of three runs. Reduce the rate for dense methods, math, or unfamiliar terminology.

Do I still add notes minutes if I highlight PDFs?

Yes. Highlighting is faster than structured notes, but you still spend time labeling, summarizing, and extracting key numbers or quotes. If you mainly highlight, lower notes minutes and increase appraisal minutes to reflect deeper evaluation.

What buffer percentage is reasonable?

For predictable work, 10-15% often covers small delays. Use 20-30% when approvals, data access, or collaborators can block progress. If you repeatedly miss targets, raise buffer before assuming you can permanently work faster.

How is efficiency different from breaks?

Breaks are planned recovery time you expect to take. Efficiency captures unplanned loss: interruptions, context switching, and low-energy periods. An 80% efficiency means only 48 minutes of each hour becomes productive work, even before breaks.

Can this support team research planning?

Yes. Estimate totals for the whole project, then assign work items to people. Keep the same efficiency assumptions per person and add coordination hours for meetings and merge reviews. Recalculate after the first milestone to calibrate team speed.
