The 20/20 rule for decluttering says you can probably let go of an item if you could replace it for $20 or less and get a new one in 20 minutes or less. It’s a quick gut-check for the stuff you’re only keeping “just in case,” and it was popularized by Joshua Fields Millburn and Ryan Nicodemus, better known as The Minimalists.
If you’ve ever stood in front of a drawer full of extra phone chargers, mystery cables, and that third pasta strainer wondering why you can’t just throw it away, this rule was built for you. It won’t solve every decluttering dilemma. But for the small, low-stakes stuff clogging up your cabinets, it’s one of the fastest decision-making shortcuts out there.
What Is the 20/20 Rule, Exactly?
The 20/20 decluttering rule is designed to help you declutter smaller, everyday items you’ve held onto “just in case,” and for those you’re struggling with, you ask yourself: can I replace this item for $20 or less, and can I replace it in 20 minutes or less? If yes to both, let it go, resting assured you can easily replace it if you need it in the future.
The idea comes straight from the source. The 20/20 rule is a genius invention by Joshua Fields Millburn and Ryan Nicodemus from The Minimalists, and in their book “Essential: Essays by The Minimalists,” they claim they’ve rarely had to replace a just-in-case item. Their whole point is that most of us are hoarding a “just in case” insurance policy we’ll never actually cash in.
If you’re stuck on something that doesn’t clearly pass, give extra thought to whether you really need to keep the item for a “just in case” situation, and you can use a maybe box, reviewing it later with a calendar reminder set to check back.
Why Not Just Set a Dollar or Time Limit Yourself?
You can, and plenty of people tweak the numbers. One popular spin-off adds a third “20” for your digital life. In 2020, Gabe Bult made a YouTube video where he added another 20 to the rule for digital things — 20 seconds. Think about the apps sitting on your phone that you haven’t opened in a year. If you could redownload it in 20 seconds, why is it still there eating up storage and mental space?
Why Do We Cling to “Just in Case” Stuff Anyway?
This isn’t just about being messy or lazy. There’s real psychology behind it. An exploratory study on hoarding behavior published by Emerald Insight found that people often keep objects “just in case,” even when the items no longer serve a purpose. The study highlights how fear of future need or loss directly shapes attachment to possessions, and when that fear rises, people pause and delay action.
It usually comes down to not wanting to feel regret later. That mental math — “what if I need this and don’t have it” — feels bigger in the moment than the actual cost of buying a replacement. The 20/20 rule works because it puts a number on that fear. Instead of an abstract “what if,” you get a concrete answer: $20, 20 minutes, done.
It’s also worth saying plainly: keeping a junk drawer or an overstuffed closet doesn’t mean something is clinically wrong with you. But if the clutter has crossed a line — if it’s blocking doorways, making rooms unusable, or causing real distress when you try to part with things — that’s a different conversation. Hoarding disorder is a recognised psychiatric condition involving a persistent difficulty discarding items and trouble organising belongings, with major impact on daily life. For everyone else, the 20/20 rule is just a tool for everyday overflow, not a diagnosis.
The Clutter-Stress Connection Is Real
There’s a reason clearing out that “just in case” drawer feels so good afterward. One study found that wives with higher stressful-home scores had flatter diurnal slopes of cortisol, a profile associated with adverse health outcomes, while women with higher restorative-home scores had steeper, healthier cortisol slopes. Translation: living in a space that feels chaotic and unfinished can quietly wear on your body all day long, even when you’re not consciously thinking about the mess.
Researchers at UCLA’s Center on Everyday Lives of Families dug into this too. One of the study’s authors explained that it’s difficult to find time to sort, organize, and manage possessions, so the excess becomes a visible sign of unaccomplished work that constantly challenges our deeply ingrained notions of tidy homes and elicits substantial stress. The “just in case” pile isn’t neutral. It’s a low hum of unfinished business every time you walk past it.
How Do You Actually Use the 20/20 Rule at Home?
Here’s the version that works without turning into an all-day project:
- Pick one category, not one room. Kitchen gadgets, extra cords, travel-size toiletries, seasonal decor — narrow categories make faster decisions.
- Pick up each item and ask both questions out loud. Could I replace this for under $20? Could I get a new one within 20 minutes, whether that’s a nearby store or a quick delivery?
- If it’s a clear yes to both, let it go immediately. Don’t set it aside to “think about it” — that’s how maybe piles turn into permanent piles.
- If it’s a partial yes, use a maybe box. Set a date to revisit it, and if you haven’t thought about it by then, it goes.
- Skip anything sentimental. This rule was built for practical, replaceable objects — not your grandmother’s necklace or your kid’s first drawing. Don’t force those decisions through a cost-and-time filter; they deserve a different process entirely.
Where This Rule Shines
It’s genuinely great for the stuff that causes low-grade guilt but no real attachment: duplicate kitchen tools, old phone cases, mystery hardware, extra mugs you never use. It’s ideal for small items, and going through overstuffed spaces often turns up plenty of everyday objects you could do without and quickly replace in an emergency, like an extra ten coffee mugs you don’t even use. It’s also handy for curbing future clutter. The rule can help you resist the urge to keep collecting more, saving money on impulse purchases you’d otherwise regret later.
Where It Falls Short
The rule has real limits, and it’s worth naming them instead of pretending it’s perfect. Not everyone has $20 or 20 spare minutes to burn without a second thought. One minimalist blogger who pushed back on the rule pointed out that for a single mom working two jobs, wasting 20 minutes on getting back a decluttered item is a lot of time, and for someone living below the poverty line, $20 can be a lot of money. If that’s your reality, adjust the numbers. There’s nothing sacred about “20.” Try $10 and 10 minutes, or whatever actually reflects your budget and schedule.
It’s also not a rule for everything. Skip it for anything irreplaceable, anything with real sentimental weight, and anything you’d genuinely be devastated to lose. This is a tool for the low-stakes 80% of your clutter, not the meaningful 20%.
A Quick Way to Test It This Week
Don’t start with your whole house. Open one drawer — the junk drawer, the bathroom cabinet, the box of cables under the TV — and run everything through the two questions. Give yourself 15 minutes, no more. You’ll be surprised how much of what you’re “saving for later” is actually just taking up space out of habit, not need.
The goal isn’t to own nothing. It’s to stop paying rent, in space and mental energy, for things you’re 99% sure you’ll never touch again. The 20/20 rule won’t make every decision for you, but it’s a fast, honest way to call your own bluff.
