You've heard "a bidet pays for itself." Cute line. But does it actually hold up, or is that just something bidet companies say to sound smart?
So, we ran the numbers. Here's what we found out.
TL;DR: A bidet attachment like the TUSHY Classic 3.0 costs over $100 once. Toilet paper costs the average household $90–$360+ every single year, forever. Most households cover the full cost of a bidet attachment in 4–9 months just from buying less toilet paper – and every roll after that is money back in your pocket.
How much does toilet paper actually cost per year?
The average person goes through roughly 100 rolls of toilet paper a year. At a typical price of $0.85–$1.20 per roll, that lands most single people between $85 and $120 a year – and it climbs fast once more people share a bathroom.
Here's the rough breakdown by household size:
- 1 person: ~$90/year
- 2 people: ~$180/year
- 4 people: ~$360/year
And that number only goes up. Toilet paper prices don't drop. Yours doesn't get a raise either.
How much does a bidet attachment cost?
A bidet attachment is a one-time purchase, not a subscription you forgot you signed up for. The TUSHY Classic 3.0 is listed at $129, installs in about 10 minutes, and doesn't need a plumber, electrician, or a single monthly payment.
That's the whole cost. No filters. No refills. No "premium tier."
What happens to your toilet paper spend after you install a bidet?
Once you're using water first, toilet paper becomes backup, not the main event. Most bidet users tell us they cut their toilet paper use by 75–80%, using it only to pat dry instead of doing all the work.
Run that against the household numbers above:
| Household Size | TP Cost/Year (No Bidet) | TP Cost/Year (With Bidet) | Annual Savings | Payback Time on TUSHY Classic ($99) |
|---|---|---|---|---|
| 1 person | $90 | ~$20 | ~$70 | ~14 months |
| 2 people | $180 | ~$40 | ~$140 | ~8.5 months |
| 4 people | $360 | ~$80 | ~$280 | ~4 months |
Bigger household, faster payback. Makes sense, more people wiping means more rolls disappearing, which means more savings once you switch.
Is a bidet attachment actually worth the upfront cost?
Yes, and the breakeven point isn't even the interesting part. The interesting part is what happens after breakeven: every roll of toilet paper you don't buy is pure savings, year after year, for as long as you own the bidet.
Do the five-year math on a household of two: that's roughly $700 in toilet paper saved against a $99 one-time cost. Toilet paper doesn't have a ceiling on what it costs you over time. A bidet attachment does.
Does this math change with an electric bidet seat?
A little – electric seats cost more upfront, so the payback window stretches out. If you want the math without the extra features, an attachment gets you there fastest. If you want warm water and a heated seat along with the savings, that's a different calculation for a different post — start with the TUSHY Spa 3.0 if warm water without electricity is the goal.
The bottom line
Toilet paper feels free because you buy it in small amounts, all the time. A bidet attachment feels expensive because you pay for it once, up front. Add up a full year and the math flips completely.

FAQs
How long does it take for a bidet to pay for itself? Most households break even in 4 to 14 months, depending on how many people live there. Bigger households recoup the cost faster because they're buying more toilet paper to begin with.
How much toilet paper does a bidet actually save? Most bidet users report cutting toilet paper use by 75–80%, since it becomes backup for drying instead of the main cleaning method.
Is a bidet attachment cheaper than toilet paper long-term? Yes. A bidet attachment is a one-time cost under $100. Toilet paper is a recurring cost that never stops and never gets cheaper.
Do I need to buy any toilet paper after getting a bidet? A little — most people still use a small amount to pat dry. You're just buying far less of it.
Does household size change the math? Yes. The more people using the bathroom, the faster a bidet attachment pays for itself, since toilet paper costs scale with people, not with the bidet.
