⏳ 90/90 Decluttering Rule Tracker

The 90/90 rule suggests that if you haven't used an item in the last 90 days and don't expect to use it in the next 90 days, it may be time to let it go. Track your items and see which ones meet that threshold.

What the tracker actually tests

One comparison per row, against a fixed threshold:

days since last used >= 90  →  Consider letting go
days since last used <  90  →  Keep

The two example rows show the split: a blender at 400 days is flagged, a winter coat at 60 days is not. Exactly 90 counts as flagged, since the test is "90 or more".

The half of the rule you supply yourself

The 90/90 rule has two questions: have you used it in the past 90 days, and will you use it in the next 90? Only the first is arithmetic, so that is all this page checks. Everything flagged yellow is a prompt to answer the second question, not a verdict.

Estimate the days rather than agonising over them. The gap between 100 and 140 changes nothing; the gap between 30 and 300 is the whole answer.

Your list is not saved anywhere. Reloading the page brings back the two sample rows, so deal with what is flagged in the same sitting.

Frequently asked questions

What is the 90/90 rule for decluttering?

If you have not used something in the last 90 days and cannot see yourself using it in the next 90, let it go. It comes from Joshua Fields Millburn and Ryan Nicodemus, The Minimalists.

Does the 90/90 rule work for clothes?

Only within a season. Apply it as you pack a season away - anything you did not wear all summer is unlikely to be worn next summer.

What if I might need it one day?

Price the replacement. If it is cheap and easy to buy again, the space is worth more than the hedge; if it is costly, irreplaceable or a genuine safety item, keep it and stop counting days.
