microsoft excel - Return a value given that a number is within a certain range

I'm looking for a little help on my scheduled withdrawals problem. I currently solve this with nested IF functions, but I'm getting more and more ranges and that leads to more and more nested IF functions. On top of this I'm running optimization so at a certain point it just explodes.

The problem:

Low        High        Amount to withdraw
600000     2000000     32000
300000     599999      20000
0          299999      8000

So a user would enter in current storage, lets say 325000 and the sheet would spit out 20000. If a user submitted 153555 the answer would spit out 8000

Like I said with just 3 ratchets using nested if clauses isn't impossible, but there can be 10 ratchets and nested if clauses aren't feasible. I'd like to solve this with Excel formulas and not a macro.
