Why is flour always 100%?

It's the defining convention of baker's percentage — the reference ingredient every other ingredient is measured against.

What does 'hydration' mean in baking?

The water percentage specifically — one of the biggest levers on final texture.

Can I use this for enriched doughs like brioche?

Not fully — this tool covers only the 4 core lean-bread ingredients.

Why would I want to convert weights back into percentages?

To document an existing recipe's actual formula so you can scale or compare it going forward.

Does yeast percentage need to change based on rise time?

Yes, in real baking practice — this tool takes your yeast percentage as a direct input.

About the Baking Ratio Calculator

Computes baker's percentages for bread dough — every ingredient expressed as a percentage of the total flour weight, with flour fixed at 100% — the standard way professional and serious home bakers scale and compare bread formulas regardless of batch size.

How to use it

Choose whether you know your percentages or your actual weights.
Enter your flour weight and water/salt/yeast percentages, or enter all four ingredient weights directly.
Read the resulting weights (or percentages) and total dough weight.

Formula

Baker's percentage: every ingredient's weight ÷ flour's weight × 100, with flour always defined as exactly 100%. From percentages: ingredient weight = flour weight × (ingredient % ÷ 100).

Worked example

500g flour at 65% hydration, 2% salt, 1.5% yeast: 325g water, 10g salt, 7.5g yeast, for a total dough weight of 842.5g.

Typical bread baker's-percentage ranges

Typical bread baker's-percentage ranges
Ingredient	Typical range	Notes
Flour	100% (fixed)	The baker's-percentage base
Water (hydration)	60-75%	Higher = wetter dough, more open crumb
Salt	~2%	Also affects fermentation speed
Instant dry yeast	1-2%	Varies by desired rise speed

Interpreting your result

This covers the 4 core ingredients of a standard lean bread formula — flour, water, salt, yeast. Enriched doughs (with fat, sugar, eggs, milk) would add more percentages this simplified version doesn't compute.

Recommendations

• Baker's percentage makes it trivial to scale a formula to any batch size.
• Comparing two recipes' hydration percentages is the correct way to judge which produces a wetter or firmer dough.
• This tool's 4-ingredient scope covers lean bread only — an enriched dough needs additional percentages.
