Egg Boiling Time
Time boiled eggs by size and desired doneness.
About Egg Boiling Time
A base boil time by doneness is adjusted slightly for egg size to hit the intended yolk texture. Two extra minutes turns a jammy yolk chalky, so timing by size and preference gives reproducible breakfasts.
Formula
Egg Boiling Time
Time = base (6 soft / 9 medium / 12 hard) + size adjustment
- size adjustment
- Extra-large eggs need about one extra minute; small ones one less

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
