A cloth diaper stash costs a few hundred dollars once. Disposables cost a few cents every time you change your baby, about 6,400 times before potty training. That is the arithmetic behind the claim that cloth saves thousands.
The pitch usually skips two things: the laundry, and which disposable you would otherwise buy. The American Academy of Pediatrics estimates that 90% or more of American babies wear disposables, and the price per diaper of a store brand and a premium brand can differ by nearly two to one.
So we priced both at Target, priced two cloth systems from the companies that make them, and costed a day of diaper laundry from federal energy and water data. This is a money comparison. What goes on your baby’s skin is your call, and your pediatrician’s.
What you’re actually choosing between
On the disposable side, we compare Target’s store brand, up&up, with Pampers Swaddlers, which costs nearly twice as much per diaper. If you have a different brand in mind, compare its price per diaper with these two.
On the cloth side there are two common setups. The cheapest is prefolds with covers: cotton pads folded into a waterproof wrap. The most convenient is the all-in-one, a waterproof diaper with the absorbent layers sewn inside, which goes on like a disposable.
What is a prefold?
A rectangle of absorbent cloth that you fold into thirds and lay inside a waterproof cover. The cover can be wiped and reused for a few changes before it goes in the wash; the prefold is washed after every change.
How many diapers a baby goes through
Pampers publishes a chart of how many diapers a day babies use in each size, and roughly how many months they spend in it, on a page reviewed by a pediatrician. We used it for both options. It starts at up to 10 a day in newborn size and falls to up to 6 a day from size 5. Because the chart gives “up to” numbers, our counts lean high.
For the end point we used 30 months. The AAP says the average age toilet training begins in the United States is between 2 and 3 years, so 2½ years is a middle case. We show what happens at 3 in the scenarios below.
| Size (months in size) | Diapers a day | Diapers used | up&up cost | Pampers cost |
|---|---|---|---|---|
| Newborn (1.6) | 10 | 487 | $81.14 | $156.50 |
| Size 1 (1.7) | 9 | 466 | $74.82 | $127.75 |
| Size 2 (2.8) | 8 | 682 | $113.59 | $207.26 |
| Size 3 (5.8) | 7 | 1,236 | $217.35 | $408.80 |
| Size 4 (6.8) | 7 | 1,449 | $275.20 | $543.19 |
| Size 5 (5.0) | 6 | 913 | $206.49 | $395.01 |
| Size 6 (5.8) | 6 | 1,059 | $279.44 | $567.32 |
| Size 7 (last 0.5) | 6 | 91 | $30.97 | $58.69 |
| Birth to 30 months | 6,383 | $1,279.00 | $2,464.52 |
Per diaper, up&up costs 16 to 34 cents and Pampers Swaddlers 27 to 64 cents, rising with the size because bigger diapers come fewer to a pack. Over 30 months the store brand costs $1,279 and Pampers $2,465: about $43 and $82 a month. That gap of $1,186 is bigger than anything laundry does in this comparison. It is the same budget-versus-premium question we asked about budget vs luxury strollers.
The assumptions
Assumptions
- One child, birth to 30 months, with the same number of changes in cloth as in disposables. Wipes, creams and trash bags are left out: you need them either way.
- Disposables: the per-size counts from the Pampers chart and the Target prices above. No coupons, subscriptions or sales.
- Prefold system: 36 Cloth-eez organic prefolds in each of two sizes from Green Mountain Diapers (Novice at $44.95 a dozen, then Intermediate at $49.95), the “3 dozen” that its buying guide calls right for most people. Eight Thirsties Duo Wrap covers per size at $15.40, from the 8 to 10 per size that guide sees most.
- All-in-one system: 24 Thirsties One Size All in One diapers at $22.95, the low end of the 24 to 36 that Esembly recommends. They fit from 8 pounds, so this family uses up&up newborn diapers for the first 1.6 months.
- Both cloth systems: two hanging wet bags at $31.90. Laundry every two days, within the two to three days Esembly recommends, using the Thirsties routine (a prewash, then a heavy hot wash with an extra rinse) and a dryer. Electric water heater.
- Cloth gets no resale value and your time is not priced. Both are discussed below.
What a cloth stash costs
| Item | Prefolds and covers | All-in-ones |
|---|---|---|
| Diapers | 72 prefolds: $284.70 | 24 all-in-ones: $550.80 |
| Covers | 16 Duo Wraps: $246.40 | Built in: $0 |
| Wet bags | 2: $63.80 | 2: $63.80 |
| Disposables until baby fits | $0 | 487 newborn diapers: $81.14 |
| Up front | $594.90 | $695.74 |
Green Mountain Diapers says the Duo Wrap’s two sizes fit its prefolds: Size One over the Novice and Size Two over the Intermediate. Prefolds and covers together cost less than all-in-ones, even though you buy two sizes of each.
What a day of diaper laundry costs
This is the number the cloth-saves-thousands pitch leaves out, and the one our old version of this article guessed. We built it from published inputs. Each laundry day is two runs of the washer: a prewash and a heavy hot main wash with an extra rinse. An ENERGY STAR washer uses 14 gallons a load, so that is 28 gallons. We assume 7 of them, half of the main run, come out of the water heater.
Heating a gallon from 58°F to 125°F, the conditions in the federal water heater test, takes 0.176 kWh in a 50-gallon electric heater at the federal minimum efficiency of 0.92. The washer motor uses about 0.23 kWh a load, and an ENERGY STAR electric dryer about 2.15 kWh for a standard 8.45-pound load. Power is priced at the U.S. average residential rate of 18.19 cents a kWh for January to August 2026.
| Per laundry day | How we got it | Cost | Over 30 months |
|---|---|---|---|
| Hot water | 7 gal × 0.176 kWh × 18.19¢ | $0.22 | $102.17 |
| Washer motor | 2 runs × 0.23 kWh × 18.19¢ | $0.08 | $38.20 |
| Dryer | 2.15 kWh × 18.19¢ | $0.39 | $178.57 |
| Water and sewer | 28 gal × DC Water rate | $0.83 | $378.27 |
| Detergent | 1.5 loads of Tide Free & Gentle | $0.30 | $139.00 |
| Total | 457 laundry days | $1.83 | $836.21 |
Water is the biggest line because we priced it at the rates DC Water charges from October 2, 2026: $11.23 per 1,000 gallons for water and $17.26 for sewer, plus two small district fees, or about 3 cents a gallon. If your water and sewer cost half that, the 30-month laundry bill falls to $647. For detergent we assume a full dose in the main wash and half a dose in the prewash, at $12.99 for 64 loads; Thirsties says most mainstream detergents are safe for cloth.

The cost side by side
| Option | Up front | Diapers or laundry | Total, 30 months |
|---|---|---|---|
| Store-brand disposables (up&up) | $0 | $1,279.00 | $1,279.00 |
| Pampers Swaddlers | $0 | $2,464.52 | $2,464.52 |
| Cloth prefolds, dryer | $594.90 | $836.21 | $1,431.11 |
| Cloth prefolds, line-dried | $594.90 | $657.64 | $1,252.54 |
| Cloth all-in-ones, dryer | $695.74 | $791.61 | $1,487.35 |
Against Pampers, cloth wins clearly: prefolds save $1,033 and all-in-ones $977 over 30 months. Against the store brand it is close. With a dryer, prefolds cost $152 more than store-brand disposables; hang them to dry and they cost $26 less. All-in-ones cost $208 more than the store brand.
Because the kit is paid up front, cloth starts behind and catches up month by month. Prefolds with a dryer pass Pampers at about month 12½. They don’t pass the store brand until month 34½, after most children in our model are out of diapers.
Costs people forget
Watch out
Check your own water and sewer rate before you buy a stash. In our model water and sewer cost more than all the electricity, dryer included. Electricity matters less: at North Dakota’s 12.46 cents the prefold total is $1,331, and at California’s 32.58 cents it is $1,683.
Cloth families still buy some disposables. The AAP notes that cloth diapers are less absorbent and need changing more often, and its diaper-rash advice says cloth users may want to use disposables until a rash heals. Travel, sitters and daycare can add more. If your baby will be in daycare, ask whether it takes cloth before you buy a full stash; our daycare vs nanny breakdown prices the care itself.
The Pampers counts work the other way. They are “up to” figures, so if your baby uses one fewer diaper a day than the chart, the store brand costs $183 less over 30 months and Pampers $353 less, while the laundry barely changes.
Scenarios: when the answer changes
A second baby in the same diapers
The prefold kit is reused and nothing is replaced. Thirsties says its diapers may last a second child, depending on your washing.
Cloth $2,267 for both children; store brand $2,558; Pampers $4,929
Line-dry and wash every third day
Prefolds, no dryer, laundry every three days, the longest gap Esembly recommends.
Cloth $1,033: $246 less than store brand
Out of diapers at 3, not 2½
Six more months in size 7 at six a day, prefolds with a dryer.
Cloth $1,598; store brand $1,651; Pampers $3,169
The second child is where cloth earns its reputation. With the kit already paid, the second child costs only the laundry, $836 against $1,279 in store-brand diapers, a saving of $443. If the covers wear out first, replacing all 16 costs $246.40 and cuts that saving to about $196. A second child changes plenty of other budget lines too, which we added up in one child vs two children.
Your time and a diaper service
Cloth also costs time: shaking out solids, running two washer cycles, hanging or drying, folding. We did not price hours we can’t measure, but you can price your own. Against Pampers, prefolds save $2.26 per laundry day. If a laundry day takes 15 minutes of your time, that pays $9.05 an hour; at 30 minutes, $4.53. Against the store brand, cloth with a dryer costs 33 cents more per laundry day, so the time is unpaid.
A diaper service takes the laundry away, but we could not find dated, published prices to compare. The test is simple: a service costs less than disposables only if it charges less than $9.80 a week compared with the store brand, or $18.89 a week compared with Pampers.
If you choose cloth, dry it on a rack
Tip
The dryer is the biggest energy cost in cloth laundry: $178.57 over 30 months at the U.S. average power price. Thirsties recommends hang drying whenever possible, and says sunlight helps with stains. Line-drying is the simplest change that makes prefolds cheaper than store-brand disposables for a single child.
Pick for line-drying: Amazon Basics foldable drying rack
Good for: a cloth family that wants to skip the dryer indoors. The listing describes a steel rack with a white finish that resists rust and mildew, an accordion design that folds flat, a size of 14.5 x 29.5 x 41.8 inches and a load limit of 32 pounds. A clothesline or rack you already own does the same job.
Beyond the money
If the environment is part of your reason for cloth, the AAP’s summary of the life-cycle studies is that disposables use more raw materials and create more solid waste, while cloth uses more water and creates more waterborne waste. Its conclusion on which is better: it still seems to be a wash. Your washing habits, like full loads and line-drying, move that balance too.
Feeding is another big running cost of the first year; we compared it in breastfeeding vs formula.
Is it worth it?
Verdict: it depends
It depends on which disposable you would otherwise buy. Against Pampers, cloth prefolds save about $1,000 over 2½ years: $1,431 including laundry with a dryer, against $2,465.
Against store-brand disposables, cloth roughly breaks even for one child: $152 more with a dryer, $26 less if you line-dry. Cloth pays off clearly when the same stash diapers a second child, or when your child stays in diapers past about 2 years 10 months.
Decision rules
- If you would buy store-brand disposables and plan one child, stay with disposables unless you will line-dry. Cloth with a dryer costs $152 more.
- If you would buy Pampers or another premium brand, compare two cheaper paths: cloth prefolds save $1,033, and switching to the store brand saves $1,186 with no laundry.
- If you plan a second child within a few years, choose cloth prefolds. The second child costs $836 in laundry against $1,279 in store-brand diapers.
- If you choose cloth, buy prefolds and covers, not all-in-ones: $1,431 against $1,487 with a dryer. Hang them to dry and prefolds cost $1,253.
- If your water and sewer cost more than about 3 cents a gallon, expect cloth to cost more than our figures; water is the largest laundry cost.
- If a diaper service quotes more than $9.80 a week, it costs more than store-brand disposables (more than $18.89 a week beats only Pampers).
Frequently asked questions
Do cloth diapers really save money?
Only against premium disposables, or across more than one child. In our 2026 model, cloth prefolds cost $1,431 from birth to 30 months including laundry, against $2,465 for Pampers Swaddlers and $1,279 for Target’s up&up store brand.
How much do disposable diapers cost for one baby?
About $1,279 from birth to 30 months in store-brand diapers at Target’s November 2026 prices, or $2,465 in Pampers Swaddlers. That assumes about 6,383 diapers, based on the Pampers chart of diapers a day by size.
How much does it cost to wash cloth diapers?
About $1.83 per laundry day in our model, or $836 over 30 months when you wash every two days and use a dryer. Water and sewer at DC Water rates are the biggest part ($378), then the dryer ($179). Line-drying brings the total to $658.
How many cloth diapers do I need?
Esembly says most families need 24 to 36 for a full-time newborn stash and should wash every two to three days. Green Mountain Diapers suggests three dozen prefolds and about 8 to 10 covers per size.
Are cloth diapers better for the environment?
It is not clear. The AAP says disposables use more raw materials and create more solid waste, while cloth uses more water and creates more waterborne waste, and concludes it still seems to be a wash.
