Nested IF for commission tiers

Intermediate

Sales commissions are often calculated using a tiered rate: higher-performing reps earn a higher commission rate. A nested IF is a practical way to apply those tier rules in a single formula.

In this sheet, monthly sales are listed in column B, and the commission tier thresholds are in columns E and F.

Your task:

  1. In cell C2, write a nested IF that calculates the commission amount for the sales in B2.
  2. Use the tier table (E2:F4) for the thresholds and rates, and lock those references so you can fill down.
  3. Fill the formula down through C9.

Hint 1

Start by testing the highest tier first (the 25,000 minimum), then the middle tier, and use the lowest tier as the final ELSE case.

Hint 2

Use absolute references for the tier table (like $E$2 and $F$2) so the thresholds and rates don’t shift when you fill down.

Hint 3

If you return a commission amount, your IF outputs should multiply the sales cell (B2) by the correct rate from column F.
