I have the following formula that multiplies the number entered in G21 by
either 49/12 or 45/12 depending if the first letter in G20 is "h" or "s".

=ROUND(IF(LEFT(G20,1)="h",(49/12)*G21,IF(LEFT(G20,1)="s",(45/12)*G21))

I would like to modify this so that the above is true for numbers entered
into
G21 that are 60 or less but greater than 0. Then, for every amount more than
60, i would like it to add 30/12 times that amount. For example:

if the number entered into G21 is 50 and G20 is "h", then the answer would be:
50*(49/12)=204.16 or 204 (rounded)

if the number entered into G21 is 65 and G20 is "h", then the anwer would be:
60*(49/12)+5*(30/12)=

Can anyone give me a little help with this?

Thanks,
