My wife and I are having our first kid in about a month and
no matter how frugal you are having a kid costs money. How much? Depends on who
you ask, but estimates peg it at approximately $250,000 and that’s before considering paying for college. A quarter ‘mil is pretty
expensive even if you don’t pay it all upfront so we set out to examine a few
ways to minimize those costs. Up first? Diapers.

The numbers
I’m going to contrast the cost of reusable versus disposable
diapers but first I want to explain the numbers behind my math. To begin we
need to know how many diapers a baby uses, approximately. Estimates vary,
anywhere from 6-15/day, but the number that came up most often was 10 and that’s a convenient number to
use because it makes the math super easy. At 10 diapers per day with 365 days
in a year you’re talking 3,650 diapers/year.
Next up is how long
your child will need to use diapers. We’re going to estimate starting potty
training at 2.5 years and assume it takes six months to get the kid fully
onboard giving us a “no diapers” estimate of three years, or 36 months. All
told that’s 10,950 diapers per child lifetime, though actual potty training
varies by kid. Where is all of this heading? Down to the big decision: are we
going to use disposable diapers, or reusable cloth diapers for raising our kid?
Average cost of disposable diapers
Now that we have our diaper use numbers, how much do diapers
cost? The internet estimated $.20/diaper while my own research on Amazon revealed a
broader range. Because the Investopedia article is a bit dated (it’s been 8
years and one financial meltdown since it was written) I’m going to use a more
conservative $.25/diaper to come up with my target for disposable diapers. With
that in mind, here is the breakdown of costs for a year of disposable diapers.

The approximate estimate for a single child’s use of
disposable diapers over their lifetime is about $3,000. Let’s take a look at
reusable diapers.
Average cost of reusable diapers
Because they don’t have a recurring cost, reusable diapers
are supposed to provide a long-term savings after an expensive up-front
investment you pay all at once. The modern world of reusable diapers is also a
lot more advanced than when I was a kid; we’re no longer talking cotton and
safety pins, but rather entire diaper “systems” designed to grow with your
child to ensure you only need one set of diapers for your child’s life.
Since a baby uses approximately 10 diapers a day you want
your reusable stack to be able to handle that load (no pun intended) without needing
to do laundry every 10 minutes. That means 20+ diapers on hand is a good target
to ensure you’re not always doing
laundry, and we’re going to estimate needing 24 in total. A set of six diapers
costs anywhere from $35-$40 on Amazon, but we’ll err on the side of expensive
for our estimates with $40 giving us a per diaper cost of about $6.70. So here’s
your cost for the first three years of baby’s life using reusables.

The comparison
It turns out there’s a pretty substantial savings comparing
reusable diapers to disposable diapers. All told you come out ahead about $2,500
over the lifetime of the child’s diaper needs, more or less. If you went the
reusables route, set aside the $2,500 into a sold index fund, and let it grow for 10 years
collecting approximately 7% in interest you’d have about $10,000 in twenty
years. That’s enough to pay for a semester of college at your local in-state
public institution. Not too bad for savings!
An additional benefit of reusable diapers is that they’re reusable. If you have additional
children? The savings begin to multiply. With your first child you pay the
costs of about $200 to buy the diapers meaning you save about $2,500. With your
second child you don’t have to pay the costs a second time meaning your savings
are now closer to the full $2,700 you’d spend on disposable diapers. Add that
to your first set of savings and you’re looking at over $5,000 in your pocket
by choosing reusable diapers over disposables.
What’s that smell?
That gives us a look at costs but doesn’t take into account
any of the other pros and cons of using disposable diapers versus reusable
diapers. First and foremost? Ease of use. Babies are truly amazing, surprising
creatures. One minute they’re melting your heart by smiling and laughing at
whatever dumb thing you’re doing to capture their attention while the next they’re
managing to process breast milk into the smelliest compound on earth and
passing it out through their intestines. There are babies out there who could
make the entire public bathroom at the Super Bowl cringe with the mightiness of
their bowel movements and when you’ve got a disposable diaper? You just scoot
that sucker off, tuck the nuclear waste up nice and tidy, and chuck it, never
to deal with that particular dosage of awful ever again.
For those on the more frugal reusable plan? You’ve got to
get the diaper changed and deal with that
liquid evil before the next installment of use. That means cleaning it and
storing it and in hands-on fashion at that. Out in public? You’ve got to have a
bag with you to store the diaper for processing later. You could pay for a
diaper cleaning service, but those costs quickly outpace the savings you get
from not using disposables. So that means doing it yourself, and that means having a strong stomach (or
just soldiering through your weak one).
Additional costs
Another area of difference between the two diapers is that
of additional costs. It doesn’t matter which diaper species you opt for, you’ll
need to purchase things like baby powder, butt paste, and wipes to make the
entire diaper changing process go more smoothly. Since you invest in those
regardless of which type of diaper is right for your family the costs on those
are a wash.
On the reusable side you may have additional costs you wouldn’t have with disposables such as
diaper liners, a used diaper container, increased water consumption from doing
laundry more, and special baby-safe detergent for the diapers. All of these
things defray the savings you’re earning a little bit, though overall they’re
not sufficient to offset $2,000 in costs. Reusables are still the more
economical bet, but the estimates I put together here are just estimates; the
real world likes to throw curveballs.
Environmental impact
My wife is a better person than me so for her the conversation
on reusable diapers needed to include talking about positively impacting the
world around her and reducing the amount of materials we consume in a given
year as a family. Depending on how you measure impact, the actual math on the
cost to the environment of disposable versus reusable diapers is surprising.
Solving for how much carbon each process uses reveals the two are about the same meaning their impact to climate change is almost
equivalent.
Additionally, the water usage and energy usage for cleaning
reusable diapers puts them on par with the continued water and energy usage of
creating new disposable diapers over and over again. You can positively impact
that number with a high efficiency washing unit or by generating your own electricity
and/or water with solar panels and a rainwater collection unit, but given that
nearly all homes in America lack those amenities the call on reusables versus
disposables comes down to which one will save you more money, not which is more environmentally
friendly.
Our decision
The reality about having your first kid is that you can do
all the math you want and then he or she comes along and blows it all to hell.
We’ve opted to go with reusable diapers to give them a test run but with costs
so low are ready to switch to disposables if we decide the additional work just
isn’t worth it. I grew up on a hog farm in Iowa so I put “baby poop” outside my
top ten list of “gross things that have touched my body” or “awful smells I’ve
encountered,” but we’ll see.
As for you? Make the decision that’s right for your family.
Or wait until my six month update when I detail for you how using reusables is
going for our family compared to disposables. Make sure to check back and find
out whether we headed off to Costco, tails between our legs to shell out the
extra cash for the easy way out, or are happy saving for college with all the
money we’re keeping from not taking
all those trips to the grocery store for diapers!
