Enter how much self-rising flour your recipe calls for and choose your preferred unit — cups or grams. The calculator returns the exact amounts of all-purpose flour, baking powder, and salt needed to make a perfect homemade substitute. Switch between US self-rising (with salt) and UK self-raising (no salt, higher baking powder) styles too.

Self-rising flour is simply all-purpose flour with baking powder and salt pre-mixed in. The baking powder acts as a leavening agent, causing baked goods to rise without needing to add separate leavening. It's commonly used for biscuits, pancakes, and quick breads.
For 1 cup of self-rising flour, combine 1 cup (120 g) of all-purpose flour with 1½ teaspoons of baking powder and ¼ teaspoon of salt. Whisk together thoroughly before using. This calculator scales those proportions to any amount you need.
The key difference is that US self-rising flour includes a small amount of salt (about ¼ tsp per cup), while UK self-raising flour does not contain salt. UK self-raising flour also uses a slightly higher ratio of baking powder — roughly 2 teaspoons per cup versus 1½ teaspoons in the US version.
No, they are not the same. All-purpose flour contains only wheat flour with no added leavening. Self-rising flour has baking powder and salt already mixed in. Substituting one for the other without adjusting your recipe will produce very different results.
You can substitute baking soda for baking powder if you also have an acid in your recipe (like buttermilk or yogurt). Use ¼ teaspoon of baking soda per cup of flour. However, baking powder is the standard leavening for self-rising flour and gives the most reliable results.
You can, but results will differ from cookies made with all-purpose flour. The built-in leavening will make cookies puff up more and spread less. It works best in recipes specifically designed for self-rising flour, so be sure to omit any additional baking powder or salt the recipe calls for.
Yes! Self-rising flour works great as a coating for fried chicken. The baking powder in the flour creates a lighter, crispier crust as the chicken fries. No modifications to the flour are needed — just season as you normally would.
Homemade self-rising flour can be stored in an airtight container at room temperature for up to 6 months. After that, the baking powder may lose its potency and your baked goods won't rise as well. Label your container with the date you made it so you can track freshness.
