Bread Proofing Time
Adjust bulk fermentation time for dough temperature.
About Bread Proofing Time
Fermentation roughly doubles per ten degrees, so the standard 21 C schedule is stretched or shortened by that factor. Even a few degrees of dough temperature swing changes proofing by an hour, so adjusting keeps bakes on time.
Formula
Bread Proofing Time
Bulk time = base x 2^((21 - dough temp) / 10)
- base
- Hours to double at 21 C for the chosen dough style
Worked example
With the default values below, Bread Proofing Time returns Bulk Ferment Time of 1.22. Change any input above and every figure here is recalculated in your browser.

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 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Bread Proofing Time calculated?
Bulk time = base x 2^((21 - dough temp) / 10) Fermentation roughly doubles per ten degrees, so the standard 21 C schedule is stretched or shortened by that factor.
Why does Bread Proofing Time matter?
Even a few degrees of dough temperature swing changes proofing by an hour, so adjusting keeps bakes on time.
What values do I need to enter?
This calculator takes 2 inputs: Dough temperature, Dough style. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
