Egg Boiling Time Calculator
Perfect timing for every egg style.
How does the egg boiling calculator work?
The boiling time for an egg depends on its size and how runny or firm you want the yolk. This calculator uses standard culinary guidelines to recommend the ideal minutes for every combination — from runny yolks in small eggs to fully set hard-boiled extra large eggs. Times assume eggs are placed in already boiling water and cooked at a gentle rolling boil.
How to use the Egg Boiling Time Calculator
Select your egg size (small, medium, large, or extra large) and your desired doneness — very soft, soft, medium, or hard. Click "Calculate" to instantly see the recommended boiling time in minutes. For consistent results, use eggs straight from the fridge and transfer them immediately to an ice bath after boiling.
Example cooking times
A medium egg takes about 4½ minutes for a very soft yolk, 6 minutes for a jammy yolk, 7½ minutes for a custard-like center, and 10 minutes for a fully set hard-boiled egg. Large eggs require roughly 30–60 seconds longer for each level of doneness.
Frequently Asked Questions
Should I start with cold water or boiling water?
This calculator assumes you add the eggs to already boiling water. Starting with cold water can make timing inconsistent. The boiling-water method gives a more predictable result for set yolk textures.
Does altitude affect boiling time?
Yes. Water boils at lower temperatures at high altitude, so eggs take slightly longer. For every 300m (1,000ft) above sea level, add about 30 seconds to the boiling time.
