About BoilMyEggs.com
A free calculator for boiling eggs when sea-level advice is wrong
Why this calculator exists
Most egg-boiling charts assume water boils at 100°C / 212°F. That is only true at sea level. At higher elevation, lower air pressure means the water in your pot is cooler when it boils, so the same clock time leaves eggs underdone — especially if you wanted a jammy yolk and got something closer to soft.
I built BoilMyEggs.com so you do not have to guess. The calculator starts from food-science temperatures for egg white and yolk, then adjusts for altitude, egg size, doneness, starting temperature, how many eggs are in the pot, and whether you drop them into already-boiling water or start them in cold water.
The timer on the homepage is the whole product. There is no account, paywall, or paid “pro” version — the site stays free and is supported by ads on reading pages and, later, optional affiliate links.
Who runs this site
I am Scott Davis. I built and operate BoilMyEggs.com. This is a personal project, not a company: there is no office, customer-support desk, or phone number behind the calculator.
If a time looks wrong at your elevation, or you have an idea for the timer, the feedback form is the best way to reach me. The same form is linked from the homepage calculator and the contact page.
Original content
The boil-time model, the calculator interface, and the articles on this site are original work — not a scraped chart with ads dropped on top. The science of boiling eggs explains why altitude, protein denaturation, and water-start method change the clock. The methods pages walk through soft-boiled, jammy, and hard-boiled eggs at elevation. The recipes index is a short list — ramen eggs, deviled eggs, and egg salad — of things to do with the eggs you just cooked.
Times are estimates. Pots, stoves, and eggs vary, and at very high elevation water may not get hot enough for every food-safety target. Use the result as a starting point, then trust a quick peel-and-check until you know your kitchen.
