Do bidets save money?

Hi, I'm the bidet guy. Short answer: a cheap bidet attachment usually pays for itself, often inside a year. A pricey electric seat usually doesn't, at least not on paper savings alone. Here's the trick most "bidets save you thousands" articles pull. They assume you'll stop buying toilet paper entirely. You won't. You'll buy less. That one correction changes the whole calculation, so let's actually do it honestly.

TL;DR

• A $35–$99 attachment typically pays for itself in roughly 3–10 months for a couple or family, just on reduced toilet paper.
• You'll still buy paper (most people pat dry), so count a reduction (say 50–75%), not elimination.
• A $300–$1,300 electric seat is bought for comfort, not savings. The paper math rarely covers it, and standby heating adds a few dollars a year.
• Plug your own roll price and household size into the math below. Don't trust a single scary lifetime number from a company that, conveniently, sells bidets.

How much do Americans actually spend on toilet paper?

I'll be honest, the headline stats are messy, and most of the dramatic ones come from companies selling bidets. The most neutral figure I found is from Statista: U.S. households spent about $131 per year (2024). But that bundles toilet tissue with paper towels and napkins, so it overstates toilet paper alone.

Survey-based estimates for toilet paper specifically land around $120–$182 per year, and a household of four can run higher. Rather than borrow one number and ask you to trust me, here's the math you can reconstruct yourself:

Annual toilet paper cost = rolls per person per year × people × price per roll

A common rule of thumb is roughly 50–100 rolls per person per year. At $1.00–$1.50 per roll, that's:

Use your real number. Look at what you actually buy. Estimates vary wildly because households do, and your bathroom is not the average bathroom.

Do you stop buying toilet paper?

No, and this is exactly where most savings claims fall apart. After a bidet, the standard move is a quick pat dry with a small amount of paper, or a reusable towel. So you're cutting paper use, not zeroing it.

A realistic cut is 50–75%. I'll use 60% in the examples below. If you go fully towel-and-dryer, your reduction is higher. If you're cautious, it's lower. Either way, "less" is the honest input. I've been doing this for years and I still keep a roll on the wall. That's just the truth.

How fast does a bidet pay for itself?

Payback is simple:

Payback (months) = bidet price ÷ (monthly toilet paper savings)

Take a two-person household spending ~$200/year on paper. A 60% cut saves ~$120/year, which is $10/month. Not retire-early money, but it adds up.

Prices are from our own catalog and move with sales, so check the live listing before you buy. (We may earn a commission on those links. It never changes what gets picked.)

For a four-person household the savings roughly double, and a cheap attachment can pay back in under two months. That's the real case for bidets-as-savings, and it's a narrow one: the cheap end, the bigger household.

When does a bidet NOT save money?

When you buy it for comfort and then tell yourself it's savings. So let's be clear-eyed:

• Electric seats ($300–$1,300). Heated water and a warm seat are genuinely nice. I love mine. But it is not a money-saving purchase. At ~$10/month in paper savings, a $599 seat takes about five years to break even, and you bought it because January is cold, not to beat the paper budget.
• Standby electricity. Electric seats keep water and the seat warm, drawing a small amount of power continuously. It's only a few dollars a year, but it's real, and it nudges the math the wrong way.
• Single-person, low-paper households. If you barely spend on paper now, there's less to save. The bidet might still be worth it, just not as a frugality play.
• Buying premium "to save money." A $1,299 washlet is a forever-bathroom splurge. Lovely. Worth it. Not frugal. Don't lie to yourself about which one it is.

So, the honest recommendation

If saving money is the actual goal, buy the cheapest well-reviewed attachment in the $35–$99 range. It's the only tier where the paper math comfortably wins, and for a couple or family it pays for itself fast, usually well within a year, sometimes a few months. Everything above it is a comfort upgrade you should buy with your eyes open, not a savings strategy in a savings costume.

Run your own numbers first: your roll price, your household, an honest reduction. If the payback still looks good at the cheap end (and for most households it will), congratulations, you've found a rare purchase that's both nicer and cheaper over time. I get weirdly happy about those.
