How to Use This Calculator
Estimate your laundry routine
Enter how many loads you run each month and how many socks typically go through each wash.
Set your loss probability
Experts blame gremlins, but you can use a probability based on experience—0.5%–1% is common folklore.
Review the sock casualty report
See the predicted number of socks lost, how many pairs that represents, and what replacements cost.
Formula
Expected Socks Lost = Loads × Socks × (Probability ÷ 100)
Expected Pairs Lost = Expected Socks Lost ÷ 2
Replacement Cost = Expected Pairs Lost × Cost per Pair
Example: 8 loads × 20 socks × 0.8% = 1.28 socks missing per month → 0.64 pairs → $3.84 at $6 per pair.
Loneliness index expresses lost socks as a percentage of total socks washed.

Frequently Asked Questions
Is the loss probability realistic?
Real studies suggest 0.5–1% per load, but adjust based on your personal experiences. This is part science, part fun.
Can I track actual losses?
Yes! Count socks before and after each load for a month to calculate your exact loss rate, then plug it into the calculator.
Does this include socks eaten by pets?
It can! Include any other sources of sock attrition in your loss probability to keep the math balanced.
Why do dryers eat socks anyway?
Socks can slip between the drum and seal, hide in washer gaskets, or stick to other garments. Static cling and human forgetfulness do the rest.
