Spaced Repetition Planner Calculator

Map review gaps, estimate retention, and spread effort. See daily sessions before deadlines become overwhelming. Stay consistent, reduce forgetting, and prepare with greater confidence.

Planner Inputs

Core Plan Inputs

First day you can actively study.
The planner schedules up to the day before this date.
All items you want covered before exam day.
Fresh material introduced on each study day.
Higher targets create shorter spacing.
1 is easier, 5 is harder.

Spacing Controls

Gap before the first review.
Controls interval growth after each review.
Caps large review gaps before the exam.
Days kept lighter near the exam.

Time Controls

Average time for one review item.
Average time for learning new material.
Used to flag overloaded study days.
Planner redistributes reviews above this limit.

Example Data Table

This example shows how new material gradually shifts toward heavier review as the exam approaches.

Formula Used

This planner uses a simplified spacing model inspired by practical repetition systems. It is designed for planning workload, not for replacing your actual flashcard app algorithm.

Available Study Days = Exam Date − Start Date

Items Introduced by Day d = min(Total Items, New Items Per Day × Studied Days)

Retention Adjustment = 1.05 − ((Target Retention − 85) × 0.01)

Difficulty Adjustment = 1.10 − ((Difficulty − 3) × 0.08)

Spacing Multiplier = Ease Factor × Retention Adjustment × Difficulty Adjustment

Next Interval = ceil(Current Interval × (Spacing Multiplier + Review Boost))

Daily Minutes = (New Items × New Item Minutes) + (Reviews × Review Minutes)

Readiness Score = weighted coverage + review depth + exam retention + workload fit + buffer support

Higher retention targets and harder material shorten spacing. Larger ease factors lengthen spacing. Buffer days protect the last stretch before the exam.

How to Use This Calculator

  1. Enter your study start date and exam date.
  2. Add the total number of cards, topics, or question sets.
  3. Choose how many new items you can realistically learn each day.
  4. Set your target retention, difficulty level, and spacing controls.
  5. Estimate how long new items and reviews usually take.
  6. Add your daily study limit and review cap.
  7. Click the planner button to generate the schedule above the form.
  8. Review the readiness score, chart, and table, then export CSV or PDF if needed.

FAQs

1. What does this planner optimize?

It balances content coverage, review spacing, available time, and late-stage buffer days. The goal is a realistic plan that supports recall by exam day.

2. Is this the same as a flashcard app algorithm?

No. This page builds a planning schedule using simplified spacing logic. It is excellent for forecasting workload, but it is not a full adaptive memory engine.

3. Why does higher target retention create more reviews?

A higher retention target means you want less forgetting before the exam. The planner responds by shortening intervals so material reappears more often.

4. What does the readiness score mean?

It combines coverage, review depth, predicted exam retention, workload fit, and final buffer support. Higher scores suggest a more stable and practical plan.

5. What if I cannot cover every item?

The calculator shows backlog items when your current pace is too slow. Increase new items per day, start sooner, or reduce total content.

6. What are final buffer days for?

They protect the last days before the exam from too much new learning. This helps you consolidate, fix weak areas, and reduce panic.

7. Why do some days exceed my time limit?

That usually happens when new learning and later reviews stack together. Lower your daily new load, shorten item times, or increase available study minutes.

8. Can I use this for subjects other than flashcards?

Yes. You can treat items as formulas, cases, vocabulary groups, question sets, or short concept blocks. The planner works well for many test-prep formats.
