Example data table

A sample input and the kind of output you will see after submitting.

Assignment Length Dates Settings Estimated total hours Planned daily hours
History Essay 1800 words Start 2026-02-20 · Due 2026-02-27 Medium, Light research, Standard format, Good quality ~6.4 ~1.0 (with 1 buffer day)
Lab Report 7 pages (275 w/page) Start 2026-02-20 · Due 2026-03-03 Hard, Heavy research, Strict format, Excellent quality ~18.2 ~1.7 (with 2 buffer days)
Tip: If you already know your writing speed, adjust difficulty and distractions until your estimates feel realistic.

Formula used

This calculator converts assignment size and constraints into an effort estimate, then spreads it across your usable days.

  1. Estimated words = Words, or (Pages × Words per page).
  2. Writing hours = Estimated words ÷ Writing rate (words/hour), adjusted by difficulty.
  3. Research hours = Reading sources × Hours per source, adjusted by research intensity.
  4. Planning hours = 0.35 + 0.06 × (Estimated words ÷ 1000), capped to 4 hours.
  5. Citation hours = 0.15 + 0.25 × Research hours.
  6. Core hours = (Writing + Planning + Citation) × Formatting multiplier × Revision multiplier + Research.
  7. Total hours = Core hours × Loss factor, where Loss factor = 1 ÷ (1 − Break% − Distraction%).
  8. Usable days = (Due − Start + 1) − Buffer days.
  9. Required daily hours = Total hours ÷ Usable days, limited by your daily capacity.

How to use this calculator

  1. Enter your start and due dates, then choose words or pages.
  2. Set difficulty and research intensity to match the assignment.
  3. Add reading sources, formatting strictness, and quality target.
  4. Enter realistic daily hours, sessions, and session length.
  5. Use break and distraction percentages to stay honest.
  6. Add buffer days for review, printing, and last checks.
  7. Press Submit to see results above the form.
  8. Download CSV or PDF to keep the schedule with you.
If the plan is not feasible, increase capacity, reduce losses, or start earlier.

Planning inputs and realistic ranges

Use the calculator to convert an assignment brief into measurable work. Typical academic pages contain 250–300 words, so the default 275 works well for essays and reports. Session length accepts 20–180 minutes, supporting Pomodoro, standard class blocks, or long lab write‑ups. Break time and distractions are modeled as percentages, helping you reflect real productivity. A 10–25% combined loss is common for phone checks, short pauses, and re‑reading.

Effort modeling and time breakdown

Effort starts with estimated words and a writing rate linked to difficulty. Easy work assumes faster drafting, while hard work reduces the rate for complex arguments, calculations, or technical language. Planning time adds structure for outlines and task setup, capped to avoid overestimating. Citation time scales with research, reflecting source tracking and reference formatting. Formatting and quality multipliers represent stricter style guides, revisions, and proofreading.

Scheduling logic and buffer protection

Available days are counted from start to due date, then reduced by buffer days to create a target finish date. This protects you from printer issues, feedback cycles, or last‑minute scope changes. Required daily hours equal total hours divided by usable days. If required hours exceed your daily capacity, the result flags feasibility and shows the number of days needed at your current capacity, so you can adjust inputs immediately.

Session design and daily capacity

Daily capacity is the smaller of your stated daily hours and the time implied by sessions per day multiplied by session minutes. This prevents optimistic schedules that ignore how you actually work. The plan also suggests minutes per session based on the planned daily workload, keeping sessions consistent and easy to follow. Weekend productivity is slightly reduced to reflect common availability patterns, while still keeping the schedule transparent.

Tracking, exports, and accountability

After submission, the result appears above the form with key indicators: total effort, required daily hours, capacity, and feasibility. A daily table lists planned hours, session count, and remaining effort, making progress measurable. Download options export the same plan to CSV for spreadsheets or to PDF for printing. Recalculate anytime to compare scenarios, such as adding research sources or increasing sessions. Store the CSV in your course folder, update actual hours daily, and you will see variance shrink as you improve estimates and habits.

FAQs

How does the calculator estimate writing time?

It divides estimated words by a difficulty-based writing rate, then adds planning, citation, and research time. Multipliers adjust for formatting strictness and revision quality.

What if my due date is before my start date?

The calculator automatically swaps the dates so the schedule remains valid. You can then correct the inputs and resubmit if needed.

Why include break and distraction percentages?

They model time lost to pauses and context switching. Increasing them raises total hours, producing a schedule that better matches real study conditions.

How should I choose buffer days?

Use one to three days for most assignments. Increase buffers for group work, strict formatting, or submissions requiring printing, approvals, or uploads.

What does 'Not feasible' mean?

Your required daily hours exceed your stated capacity. Increase daily hours, add sessions, reduce losses, start earlier, or adjust scope until feasibility becomes Yes.

Do downloads include my schedule table?

Yes. CSV exports the full summary and day-by-day plan. PDF includes a concise summary and the first 30 schedule rows for quick reference.
