How to use subcalculations (multistep formulas) in your calculations
The calculator block is able to chain endless subcalculations to perform multistep formulas.
When to use
Use the calculator block when you want to perform calculations inside your form. If you want to perform advanced calculations that require subcalculations, you can also do this. For example:
- First calculate the total price of selected products. And then use the result of that to do another operation;
- Perform a formula, for example to calculate the BMI: weight / (height*height).
These are just some examples. Basically you can calculate anything you want with the calculator block. Please have a look at our calculator features overview to see everything you can do with the calculator block.

You can determine if you want the result of the subcalculation to be available for other blocks and in your dataset, for example to show the outcome of the subcalculation to your respondent. The following settings are available:
Make answer available for other blocks- Enable this to make the outcome of the subcalculation available to use in other blocks and even in logic branches;Make answer exportable and include it in the dataset- Enable this to save the outcome of the subcalculation to your dataset, so you can use it in results, exports, notifications and webhooks;Set an alias for this answer- Set an alias that gets used in the dataset (more information about aliases over here).
