Right now, to format values pulled from a Currency field in a Formula field, users have to use something akin to the following formula to get “$65,756” to display as such. Otherwise, AirTable displays it as “65756”, no commas, no currency symbol:

IF(
LEN(CONCATENATE({Trip Budget}))<4,
{Trip Budget},
IF(
AND(LEN(CONCATENATE({Trip Budget}))>3,LEN(CONCATENATE({Trip Budget}))<7),
LEFT(CONCATENATE({Trip Budget}),LEN(CONCATENATE({Trip Budget}))-3)&","&RIGHT(CONCATENATE({Trip Budget}),3),
IF(
AND(LEN(CONCATENATE({Trip Budget}))>6,LEN(CONCATENATE({Trip Budget}))<10),
LEFT(CONCATENATE({Trip Budget}),LEN(CONCATENATE({Trip Budget}))-6)&","&LEFT(RIGHT(CONCATENATE({Trip Budget}),6),3)&","&RIGHT(CONCATENATE({Trip Budget}),3),
IF(
AND(LEN(CONCATENATE({Trip Budget}))>9,LEN(CONCATENATE({Trip Budget}))<13),
LEFT(CONCATENATE({Trip Budget}),LEN(CONCATENATE({Trip Budget}))-9)&","&LEFT(RIGHT(CONCATENATE({Trip Budget}),9),3)&","&LEFT(RIGHT(CONCATENATE({Trip Budget}),6),3)&","&RIGHT(CONCATENATE({Trip Budget}),3),
)
)
)
)

This is obviously inconvenient, and it doesn’t even take into account decimals or amounts greater than $999,999,999.

I propose a new formula function that operates something like this:

CURRENCY([number or field reference], [currency symbol]) => CURRENCY(12345.6,"$") = $12,345.60
