Try something like this:

For sales amount in A1

B1: =100+MAX(A1-30000,0)*3%


Does that help?

We're leasing a property and the terms of our lease state that we will pay
$100/month plus 3% of sales in EXCESS of $30,000/per month.

So, if our sales were $40,000 for the month, we'd only pay 3% on $10,000.

Please help! Thanks!
