Have you ever thought about how much money you could save if you only pooped at work versus pooping at home? Look no further.

Let’s walk through the calculation:

Average poops: Assuming you average 1 poop per day for 5 workdays, this comes out to 5 poops per week or 250 poops per year (I used 50 weeks with 2 weeks of vacation).

Water bill: My toilet offers two flush options: number 1 and number 2. For this example, we will use number 2. My toilet averages 1.6 gallons per flush if I push the number 2 button. You should also be washing your hands for a minimum of 20 seconds after each restroom visit. I put a measuring cup underneath my faucet and calculated how much water I would use on an average wash time of 20 seconds. I came up with 0.25 gallons/wash. Flushes: 250 poops/year x 1 flush/poop x 1.6 gallons/flush x $5.56/1,000 gallons = $2.22/year

Washing Hands: 250 poops/year x 1 hand wash/poop x 0.25 gallons/wash x $5.56/1,000 gallons = $0.35/year

Wastewater bill: My wastewater rate is $7.58/1,000 gallons. So using the numbers calculated above I get the following costs for wastewater. Flushes: 250 poops/year x 1 flush/poop x 1.6 gallons/flush x $7.58/1,000 gallons = $3.03/year

Washing Hands: 250 poops/year x 1 hand wash/poop x 0.25 gallons/wash x $7.58/1,000 gallons = $0.47/year

Electricity bill: I installed a fart fan in my bathroom that I wired to run whenever the light is on. So, unless I poop in the dark, the lights and fan are on at the same time and using electricity which needs to be accounted for. I have a Panasonic model that is very quiet—almost too quiet—and operates at 21.1 watts. I have two light bulbs in the bathroom. I use Philips LED bulbs which have a very small power consumption—only 8 watts. For this calculation, we need to know how long the average poop takes. Obviously, this is variable, but I typically like to sit down and make a couple of memes until my legs start to feel numb. This is approximately 15 minutes on average. My electricity costs are $0.10219/kWh. Fart Fan: 250 poops/year x 15 minutes/poop x 1 hour/60 minutes x 21.1 watts x 1 kW/1,000 watts x $0.10219/kWh = $0.13/year

Light bulbs: 250 poops/year x 15 minutes/poop x 1 hour/60 minutes x 8 watts/bulb x 2 bulbs x 1 kW/1,000 watts x $0.10219/kWh = $0.10/year

Hand soap: We use Mrs. Meyers liquid hand soap. On Amazon, it’s currently priced at $2.10/fl oz. The average person takes 1.5 mL of soap from a dispenser. 250 poops/year x 1 hand wash/poop x 1.5 mL soap/hand wash x $2.10/fl oz soap x 1 fl oz/29.5735 mL = $26.63/year

Toilet paper/wipes: Toilet paper is an investment in our household. We use Charmin Ultra Strong Clean Touch toilet paper that is currently $0.34/100 sheets. The average consumer uses 10 sheets per use. I probably use twice the average—especially if I’m covering the toilet seat with paper because I don’t know whose nasty ass has been on my seat. Sometimes it’s also nice to use a wet wipe or two for that refreshing feeling. We like to use WaterWipes which currently run at $0.06/wipe. Toilet paper: 250 poops/year x 20 sheets/poop x $0.34/100 sheets = $17/year

Wipes: 250 poops/year x 1 wet wipe/poop x $0.06/wet wipe = $15/year

Plumber: Some people do more damage to their toilets than others depending on how frequently you visit Chipotle. A safe assumption would be that you’d have to call a plumber once per year. Plumber: $150/year

Scented sprays/candles: If you don’t have a fart fan or just want to be courteous to everyone using the bathroom after you drop a bomb, you should be using a scented spray or candles. Poo-Pouri spray on Amazon has approximately 200 sprays per 4 oz bottle. We’ll assume we go through 1 Scentorini candle set per year. Sage and rosemary are fantastic smells, believe me. Scented spray: 250 poops/year x 1 spray/poop x $11.50/200 sprays = $14.38/year

Candle set: $16.99/year

Toilet bowl cleaner: Pooping 250 times per year in your own toilet will definitely leave some residue that needs to be cleaned up. This 4 pack of Clorox would probably last all year. Toilet bowl cleaner: $11.99/year
