Some purchases just keep on giving. They cost a bit more upfront, but they deliver value day after day, year after year, until the price you paid becomes almost laughably small compared to the benefit you received.
These are the best cost per use items -- the purchases that practically pay for themselves through sheer volume of use, durability, and impact on your daily life. After analyzing hundreds of products across every major spending category, here are 20 that consistently deliver the lowest cost per use.
How We Define "Best" Cost Per Use
For this list, we evaluated items based on three criteria:
- Frequency of use -- How often do most people actually use this item?
- Durability -- How long does it last with normal care?
- Value delivered per use -- Does each use provide meaningful benefit?
An item with a $0.10 cost per use that you only use monthly did not make the cut if an alternative at $0.30 per use gets used daily and impacts your quality of life more significantly. This list prioritizes items that most people will genuinely get massive value from.
The 20 Best Cost Per Use Purchases
1. A Quality Mattress
- Typical cost: $800-1,500
- Uses: Every night for 8-10 years (2,920-3,650 uses)
- Cost per use: $0.22-0.51
You spend a third of your life sleeping. A mattress that properly supports your body improves your sleep, energy, mood, and health every single day. At roughly $0.30 per night, a good mattress is arguably the best investment you can make.
2. A Reliable Pair of Everyday Shoes
- Typical cost: $100-180
- Uses: 300-500 wears
- Cost per use: $0.20-0.60
Comfortable, versatile shoes that you reach for almost every day deliver extraordinary cost per use. Invest in a pair that fits well and suits your style, and you will wear them into the ground.
3. Cast Iron Skillet
- Typical cost: $30-60
- Uses: 1,000+ (lasts a lifetime with care)
- Cost per use: $0.03-0.06
A cast iron skillet improves with age, requires almost no maintenance beyond basic seasoning, and can be passed down through generations. At three cents per use, nothing in your kitchen comes close.
Calculate the real cost before you buy
Stop guessing. Skip or Buy shows you the cost per use of anything — so you only buy what's truly worth it.
4. Quality Chef's Knife
- Typical cost: $80-200
- Uses: 2,000+ over 10-20 years
- Cost per use: $0.04-0.10
A good chef's knife used daily for meal prep is one of the most satisfying purchases you will ever make. It makes cooking faster, safer, and more enjoyable -- and it lasts decades with proper sharpening.
5. Reusable Water Bottle
- Typical cost: $25-40
- Uses: 1,000+ over 3-5 years
- Cost per use: $0.03-0.04
Beyond the incredible cost per use, a reusable water bottle saves you from buying disposable bottles at $1-3 each. If it replaces even one purchased bottle per week, it pays for itself in a month.
6. Quality Bath Towels
- Typical cost: $30-60 each
- Uses: 500+ washes over 5-10 years
- Cost per use: $0.06-0.12
You use towels every single day. Cheap towels thin out, lose absorbency, and need replacing every year or two. Quality towels stay plush and functional for years.
7. A Solid Backpack or Daily Bag
- Typical cost: $80-200
- Uses: 500-1,500 over 3-7 years
- Cost per use: $0.05-0.40
Your daily bag goes everywhere with you. A well-made backpack or tote that you actually enjoy carrying will be used thousands of times.
8. Electric Kettle
- Typical cost: $30-60
- Uses: 1,500+ over 5+ years
- Cost per use: $0.02-0.04
If you drink coffee, tea, or even just use hot water regularly, an electric kettle gets used at least once a day, often multiple times. At two to four cents per use, it is practically free.
9. Quality Jeans
- Typical cost: $80-160
- Uses: 200-400 wears over 2-5 years
- Cost per use: $0.20-0.80
Good denim that fits well becomes a wardrobe staple worn multiple times per week. When a pair of jeans hits that perfect broken-in softness, you will reach for them constantly.
10. A Comfortable Desk Chair
- Typical cost: $300-800
- Uses: 1,500-3,000+ days
- Cost per use: $0.10-0.53
If you work from home or spend significant time at a desk, a quality ergonomic chair prevents back pain, improves posture, and lasts for many years. It is one of the most impactful cost per use purchases for office workers.
11. Library Card
- Typical cost: $0 (free in most places)
- Uses: Unlimited
- Cost per use: $0.00
We had to include it. A library card gives you access to thousands of books, audiobooks, movies, and often digital resources -- completely free. The cost per use is literally zero, and the value is immeasurable. If you are not using your local library, you are leaving extraordinary value on the table.
12. Quality Pillows
- Typical cost: $50-100
- Uses: Every night for 2-3 years (730-1,095 uses)
- Cost per use: $0.05-0.14
Like mattresses but cheaper and replaced more frequently, good pillows meaningfully impact sleep quality. At well under a dollar per night, quality pillows are a no-brainer.
13. Insulated Travel Mug
- Typical cost: $25-35
- Uses: 500+ over 2-3 years
- Cost per use: $0.05-0.07
An insulated mug used for your daily coffee or tea gets used 365 times a year. It also saves you money every time it prevents you from buying a takeaway coffee.
14. A Basic Tool Kit
- Typical cost: $50-100
- Uses: Hundreds of times over a lifetime
- Cost per use: $0.10-0.50
A hammer, screwdrivers, pliers, measuring tape, and a wrench set cover 90% of household repair and assembly needs. Every time you fix something yourself instead of calling a professional, the cost per use drops further.
15. Sunscreen
- Typical cost: $10-20 per bottle
- Uses: 30-60 applications per bottle
- Cost per use: $0.17-0.67
This is a cost per use item where the value delivered per use is extraordinary. Daily sunscreen use prevents skin damage, premature aging, and skin cancer. The return on investment is your health.
16. Quality Underwear and Socks
- Typical cost: $10-25 per pair
- Uses: 100-200 wears per pair
- Cost per use: $0.05-0.25
Underwear and socks are worn every day and directly impact comfort. Quality options maintain their shape, elasticity, and comfort far longer than budget alternatives, delivering superior cost per use.
17. A Slow Cooker or Dutch Oven
- Typical cost: $40-80 (slow cooker) or $80-300 (Dutch oven)
- Uses: 200-500+ over many years
- Cost per use: $0.08-0.60

- Typical cost: $100-150
- Uses: Daily for 5+ years (1,825+ uses)
- Cost per use: $0.05-0.08
For regular readers, an e-reader is a revelation. It replaces hundreds of physical books, is lighter than a single paperback, and its battery lasts weeks. Daily readers will hit a cost per use under a dime within the first year.
19. Quality Rain Jacket
- Typical cost: $100-250
- Uses: 100-300 over 5-10 years
- Cost per use: $0.33-2.50
A reliable rain jacket that you actually trust to keep you dry becomes a grab-and-go staple during rainy months. Cheap rain jackets that leak or deteriorate get replaced frequently, driving up their true cost.
20. Noise-Cancelling Headphones
- Typical cost: $250-400
- Uses: Daily for 3-5 years (1,095-1,825 uses)
- Cost per use: $0.14-0.37
For commuters, remote workers, students, or anyone who values focus, quality noise-cancelling headphones deliver value every single day. They improve concentration, make travel more pleasant, and protect your hearing in noisy environments.
The Pattern: What These Items Have in Common
Looking at this list, several patterns emerge:
They solve daily problems. Every item on this list addresses a need you have almost every day -- sleeping, eating, drinking, working, commuting, dressing.
They are durable. These are not disposable products. Most last years, some last decades, and a few (like cast iron) last generations.
They improve with time. Many of these items -- jeans, cast iron, leather bags, a good mattress once broken in -- actually get better the more you use them.
They replace inferior alternatives. A quality item that replaces a stream of cheap replacements saves money even beyond the cost per use calculation.
They compound in value. The reusable water bottle saves on disposable bottles. The tool kit saves on handyman calls. The headphones improve your work output. The value they deliver multiplies over time.
Your Action Plan
You do not need to buy all 20 items at once. Here is a practical approach:
- Audit your daily routine. What do you use, touch, or interact with every single day?
- Identify the weak links. Which of those daily-use items are cheap, worn out, or frustrating?
- Upgrade one at a time. Replace one weak link with a quality alternative. Use it, appreciate it, and notice how low the cost per use becomes.
- Repeat. Each month or quarter, upgrade one more daily-use item.
Over time, you will build a collection of belongings that are genuinely excellent, used constantly, and cost almost nothing per use. That is not just smart shopping -- that is a better way to live.
