The formula field instantly performs calculations based on values added to other fields on the entry form. To create your formula you'll need to reference the slugs or short titles of these fields. This must be enclosed in curly braces.

**Note:**all field types are supported excluding table fields, content fields, and other formula fields.

## Configure a formula field

- In the
**Manage**workspace, navigate to*Entries*and click**Edit form** - Locate where you'd like to place your formula field click the
**+**that appears - In the configuration tray on the right side of the page, select
**Formula**from the**Field type**drop-down - Provide a
**Label**and**Short title** - If desired, add in
**Hint**and/or**Help text**to provide context to entrants - In the 'Options' section, key in your formula utilising the functions listed below
- Under the 'Access' heading, choose whether this field is hidden from entrants by deselecting the
**Read**checkbox if necessary

**Tip:**hidden fields can be shown to judges during the evaluation process, for more information see: Show/hide fields for judging. **Save**when finished

## Examples

If you want to calculate the year-on-year growth in revenue for two fields with short titles "2020" and "2021" you would reference each field as {2020} and {2021} in your formula. Here's how it will look:

({2021}-{2020})/{2020}*100

To round the result to two decimal places you can use the round function as follows:

round(({2021}-{2020})/{2020}*100,2)

## Available functions

The formula field supports a number of different functions, many of which will be familiar if you use formulas in Excel and other spreadsheet tools. Here are some examples of what you can do.

### Number and currency fields

AverageTakes the average of the specified fields |
average({field1},{field2},{field3},{field4}) |

SumSums the specified fields |
sum({field1},{field2},{field3},{field4}) |

MinReturns the smallest number of the specified fields |
min({field1},{field2},{field3},{field4}) |

MaxReturns the largest number of the specified fields |
max({field1},{field2},{field3},{field4}) |

RoundRounds to specified number of decimal places |
round(number,count) |

RoundupRounds up to specified number of decimal places |
roundup(number,count) |

RounddownRounds down to specified number of decimal places |
rounddown(number,count) |

### Strings

ConcatenateCombines several text strings into one string |
concatenate({field1},{field2},...{fieldn}) |

ExactReturns true if both strings are exactly the same |
day({field1},{field2}) |

LeftExtracts a given number of characters from the left side of a text string. |
left({field},4) |

LowerConverts the text to lowercase |
lower({field}) |

MidReturns a substring of a given length starting from a specific position |
mid({field},start_position,length) |

ProperCapitalises the first word of a string |
proper({field}) |

ReplaceReplaces a substring of a given string |
replace({field},start_position,length,"new string") |

RightExtracts a given number of characters from the right side of a text string. |
right({field},4) |

### Dates

TodayReturns today's date |
today() To format the date use text(today(),"MM/DD/YYYY") |

DaysCalculates the difference between two date values |
days({field1},{field2}) |

MonthReturns the month for a date value |
month({field1}) |

YearReturns the year for a date value |
year({field1}) |

DayReturns the day for a date value |
day({field1},{field2}) |

EdateShifts the date by the given number of months |
edate({date},months) To format the date use text(edate({start},3),"dd/mm/yyyy") |

HourReturns the hour for a given time |
hour({time}) |

NowThe current date and time |
now() To format use: text(now(),"dd/mm/yy hh:mm:ss") |

WeekdayReturns the number that corresponds to a day of the week |
weekday({field}) |

WeeknumReturns the number that corresponds to the week of the year |
weeknum({field}) |

### Engineering

bin2decConverts a binary number to decimal |
bin2dec({field}) |

bin2hexConverts a binary number to hexadecimal |
bin2hex({field}) |

dec2binConverts a decimal number to binary |
dec2bin({field}) |

dec2hexConverts a decimal number to hexadecimal |
dec2hex({field}) |

deltaReturns true(1) if both numbers are equal otherwise false(0) |
delta({field1},{field2}) |

### Information

isnumberReturns true if the field contains a number |
isnumber({field1}) |

isevenReturns true if the field contains an even number |
iseven({field}) |

isoddReturns true if the field contains an odd number |
isodd({field}) |

istextReturns true if the field contains text |
istext({field}) |

### Logical

ifIf/then test |
if({field1}>1000,"then value1", "otherwise value2") |

addReturns true if all arguments are true |
and({num1}=3, {num2}=3) |

orReturns true if at least one argument is true |
or({num1}=3, {num2}=3) |

## Good to know

- Unlike Excel or many other spreadsheet tools, it isn't necessary to add a = symbol to indicate the start of a formula.
- The formula is stored referencing the field slugs, not the short title. If a field's short title is changed later, existing formulas that reference that field will not break.
- Calculated values are stored on the entry record when the entry is saved. This will allow a formula field column to be added to the many of the views in the platform, such as
*Entries*in the**Manage**workspace. - Changes to a formula after entries already exist with saved values will trigger a recalculation of all stored values.
