Bidet vs. Toilet Paper: Cost Comparison

The financial comparison is basically recurring paper expense versus an upfront bidet purchase, with operating costs added when you want a more complete model.

The simple model

If a household spends $25 per month on toilet paper and a bidet reduces that paper spending by 50%, the modeled savings are $12.50 per month. A $300 bidet would therefore have a simple payback period of 24 months.

This is an illustrative example, not a prediction of actual savings.
