I have a Smartsheet with two text/number-type columns:
- Credit Consolidated
- Credit Required by Proposal
I’d like to add a third column (Formula type) that divides Credit Consolidated by Credit Required by Proposal and shows the result as a percentage string (e.g. 130%). Smartsheet doesn’t offer native percentage formatting for formula columns, so I’ve tried a couple of approaches:
-  Using TEXT
 
 =IFERROR(
 TEXT(
 [Credit Consolidated]@row  / [Credit Required by Proposal]@row;
 "0%"
 );
 "0%"
 )
 
- Multiplying, rounding and concatenating
 =IFERROR(
 CONCATENATE(
 ROUND(
 [Credit Consolidated]@row  / [Credit Required by Proposal]@row  * 100;
 0
 );
 "%"
 );
 "0%"
 )
 
However, both formulas either return “unparseable” or unexpected values. I know I need to wrap the division in IFERROR, and I’m using the correct column names, but I can’t seem to get a valid result.
- What is the correct syntax (using the appropriate argument separators for my locale)?
- Is there a built-in Smartsheet function or workaround I’m missing to format a formula result as a percentage string?
- How can I reliably display something like 130% (or with 1–2 decimal places) without errors?
Any guidance or working formula examples would be greatly appreciated.
