Modifying a price data column by a factor

[groovyls]

I would appreciate your help in programming an Access table so I can multiply
a column of price values by a factor and copying it in place of the original
column.

To permanently change the value of each record in the table use an
Update query.
To increase the value by let's say 15%:

Update YourTable Set YourTable.[PriceField] = [PriceField]*1.15;
