Flour Blend Percentage Calculator
Divide a total flour weight among base, whole-grain, and rye portions using two specialty-flour percentages.
Build the blend from one basis
Percentage allocation is not functional equivalence
The two specialty percentages share one flour basis. Their sum cannot exceed 100% without making the base portion negative.
A flour blend changes absorption, gluten potential, fermentation, flavor, and color. Preserving total flour does not preserve dough behavior.
Blend percentage does not predict absorption
Name flours precisely enough to repeat the blend. Extraction rate, milling, protein, and supplier can matter more than a broad white-or-whole label.
A thirty-percent specialty blend
Enter total flour of 1500 g, whole-grain flour of 20 %, rye flour of 10 %. In this case, expect base flour of 1,050.0 g and whole-grain flour of 300.0 g. Confirm that the displayed base percentage plus both entered specialty percentages totals 100%.
Weigh the blend consistently
- Set the total flour basis.
- Assign whole-grain and rye percentages.
- Confirm a nonnegative base percentage.
Allocating one flour basis
Method basis: Both specialty percentages use total flour as their basis, and base flour receives the remaining share.
After blending flour, it may be useful to recheck water against the blend.
Flour identity and absorption
Whole grain can change fermentation as well as absorption.
A small rye addition may be operationally significant.
Blend before sampling if the production method depends on uniform distribution.
Record flour identity
Keep total flour, each percentage and weight, flour product names, lot changes, and any resulting hydration or mixing adjustment together.
When adding a third specialty flour, calculate its weight from the same total and subtract its percentage from the base portion. Do not recalculate each addition from a shrinking remainder.
Run absorption tests at production mixing intensity. A hand-mixed sample can understate the effect of bran, damaged starch, or high-extraction flour on the full process.
If a house blend is premixed and stored, reconcile the theoretical batch with the weighed amount packed. Dust, transfer residue, and scale resolution can change the usable total.
For purchasing, translate each flour weight into full bags only after the formula blend is approved. Package rounding belongs outside the baker’s percentages; otherwise a convenient bag count can quietly change the blend placed in the mixer.
Sifting or screening a whole-grain flour can change the material that actually enters the dough. If bran is removed or returned later, identify that stream separately instead of assuming the bag label still describes the final blend.
Flour-blend questions
Can I use this for any two specialty flours?
Yes. Relabel them in your working notes while preserving their percentages.
What happens if the two percentages exceed 100%?
The displayed base portion stops at zero, but the formula is invalid; reduce the specialty percentages until their total is at most 100%.
