What this tool does
Estimate total minutes, study days, and new items per day with review included. Enter the number of items, their difficulty, and your daily time to build a review-aware memorization estimate. Use the result to choose and plan your next study action with confidence.
Free, no sign-up, no ads, and fully browser-based
How to use it
- 1
Enter the number of facts or terms and their difficulty.
- 2
Set the minutes available per day and target recall level.
- 3
Review the estimated days and add a buffer before the deadline.
Memorization includes later retrieval, not only first exposure
The estimate starts with seconds per item, adjusts that time for difficulty, and multiplies it by review overhead based on the target recall level. Dividing the total minutes by daily study time produces study days and a new-item pace. It is not a biological prediction. Existing knowledge, the quality of prompts, sleep, and interference can change the result, but including review prevents the common planning mistake of treating first exposure as completion.
If the estimate is too long, improve the unit before extending every session. Split dense items, attach them to something you know, and test the answer without looking. Mark difficult items and revisit them after increasing delays instead of rereading the entire list each day. Build buffer days for a closed-book check, because success immediately after studying does not show that the memory will survive the exam interval.
Your inputs and calculations stay in this browser, and no account is required. Save or print the result if you need a record, then turn it into one concrete next action. A calculator is most useful when it changes the next study session: isolate the weakest material, express it as a question you can answer without notes, and schedule another attempt after a short delay. Official rules from your school, course, test provider, or assignment always take priority over this planning estimate.

Frequently asked questions
How many seconds does it assume per item?
The standard baseline is 30 seconds for first exposure, adjusted from 15 to 75 seconds by difficulty.
Will I definitely memorize everything by that day?
No. It is a workload estimate. Add buffer time and test recall after delays to measure actual retention.
Does this tool upload my study data?
No. The calculation runs in your browser. Avoid entering private information, and copy or print any result that you need to keep.
Can I use the result as an official score or decision?
Use it as a planning estimate. Your syllabus, school, test provider, and official score report take priority over this browser calculation.
