If you need to perform calculations, assign values, or insert text into a field conditionally, Jotform provides a powerful feature called Update/Calculate Field conditional logic. This feature enables you to dynamically change form field values based on specific conditions.
To insert text or calculation into a field
- In the Form Builder, go to Settings at the top.
- Select Conditions on the left.
- Add a new Update/Calculate Field condition.
- Set DO to Calculate a field’s value.
A new section will appear where you can edit and build your formula.
Performing Calculations
The Update/Calculate Field conditional logic allows you to perform calculations conditionally. In the following example form, the conditional logic will output the product of two fields only if the first one is filled.
Here’s what the conditional logic looks like:
- IF: Multiplicand
- STATE: Is Filled
- DO: Calculate a field’s value — Multiplicand * Multiplier
- SUMMARY: Product
The field labels’ trailing [0-9] indicates that their values are numeric.
Inserting a Text
Aside from dynamic values, you can also assign or insert specific texts into a field conditionally using Update/Calculate Field by entering the value in your DO statement. In the following example form, the conditional logic will insert “Hello World” into the Output field when “Yes” is selected.
Here’s what the conditional logic looks like:
- IF: Insert “Hello World” into Output?
- STATE: Is Equal To
- VALUE: Yes
- DO: Calculate a field’s value — “Hello World”
- SUMMARY: Output

Great guide! For anyone looking to update or calculate field values conditionally in Jotform, the Update/Calculate Field feature is really helpful. Just remember to check the conditions carefully to ensure the right data gets inserted when the specified criteria are met. If you're new to this, following the steps in the Form Builder and watching the tutorial video can make the process much smoother!

When do calculations happen?
For example, if I have 3 fields such as:
Cost of item
Number ordered
Total cost
Where I set the Total cost = Cost x Number,
But if the user then goes back to change the cost of the item, does it automatically recalculate the Total Cost?

Vasúti kocsik számozásával kapcsolatban van egy kis problémám:
1 - Mivel a vasúti vagonok számozása egy 12 számjegyből álló számsor, aminek az utolsó szájegye az ellenörző szám, amivel a kocsiszám hellyeségét tudjuk igazolni.
Ezt a számot szeretném kiszámíttatni a programmal, de sajnos nem igazán tudom, hogyan kell.
2 - Az ellenörző számot a következő képpen kell kiszámolni: : a páratlan helyen álló számokat 2-vel szorozzák, a páros helyen állókat 1-gyel, és mindegyik szorzatban veszik a számjegyek összegét; majd az így kapott 11 számot összeadják, végül a 12. jegyet úgy választják meg, hogy az előbbi összeghez hozzáadva 10-zel osztható számot kapjanak. Pld, ha az 51553930016 tizenegy-jegyű számból indulunk ki: a 11 jegyű szám: 5 1 5 5 3 9 3 0 0 1 6 szorzó: 2 1 2 1 2 1 2 1 2 1 2 szorzat 1 0 1 1 0 5 6 9 6 0 0 1 1 2 a jegyek összege: 1 1 1 5 6 9 6 0 0 1 3 akkor az összeg: 1+1+1+5+6+9+6+0+0+1+3= 33, tehát az utolsó, 12. jegy a 7 lesz. A vasúti kocsi 12 jegyű száma: 515539300167.
Ezt hogyan tudnám kiszámíttani az űrlapon???
3 - Valamint: a telefonos alkalmazásban ezt hogyan tudom megjeleníttetni, úgy hogy a 12 számjegy elférjen???
Nagyon várom a választ!
További szépnapot!!

I have a registration form for a camp where participants state their gender (male/female/undetermined). Total space in the camp is 80 spaces. I would like to stop registration for males or females (plus undetermined) at 40 each gender.
How can I do this using the calculate function? I tried, but it won't let me add to more than one counter.
