How to Calculate Commissions in Excel with VLOOKUP
Bottom line: Learn how to calculate commissions in Excel for a basic tiered plan and rate table using the VLOOKUP function.
Skill level: Intermediate
Calculating commissions in Excel can be a very tricky task. This is especially true if you have tried to use multiple IF statements to calculate commissions for each tier in a rate table.
This article will explain how to use the VLOOKUP function to make this process much easier. The secret is setting the last argument in the vlookup to TRUE, to find the closest match.

Calculating Commissions with VLOOKUP
With a simple commission plan you typically have a rate table that lists the payout rate at each level of sales. As the sales rep makes more sales, his/her payout rate will typically increase.
The payout rate could be a flat dollar amount, percentage of revenue, percentage of quota, etc. The job of the VLOOKUP is to find the rep’s sales amount in the rate table, and return the corresponding payout rate.
For this example our commissions plan looks like the following:
- Rep sells $0-$50,000, they earn 5%
- Rep sells $51,000-$100,000, they earn 7%
- Rep sells $100,001-$150,000, they earn 10%
- Rep sells over $150,001, they earn 15%
The rep will make a certain amount of sales during the month. He/she will earn a certain payout rate depending on the level of sales achieved.
We can use a VLOOKUP formula to calculate the payout rate for a given sales amount (lookup value). For this to work we need to set the last argument in the vlookup [range_lookup] to TRUE.
With the last argument set to TRUE, vlookup will find the closest match to the lookup value that is less than or equal to the lookup amount. This basically allows us to find a value between ranges of two numbers (tiers).
How to Setup the Rate Table
When putting this rate table in Excel, you only need to list the tier minimum for the lookup range. Again the VLOOKUP will search for a “closest match” that is less than or equal to the lookup value. If it finds a value that is greater than the lookup value, then it will return the previous row.
In this example for a commissions rate table, the first row in the lookup range needs to be zero. This is because the sales rep could potentially have sales of $0 and the lookup value would be zero. If the lookup value (sales amount) were a negative number, then the vlookup would return an error.
It is important to know this and setup your rate table for all possible lookup values.
If the sales amount is greater than the last row in the lookup range, then the vlookup will return the last row. For example, if the rep made sales of $175,000 then vlookup would return 15%.
Calculate Commissions to Return a Dollar Value
The payout can also be returned as a dollar value, instead of a percentage. With this setup the payout will be a flat rate.
This means that the payout will be the same, regardless of what the sales amount is within the tier. In the example below, if the payout will be $1,000 if the sales amount is $55,000 or $95,000.
The payout is NOT on a sliding scale. It is a flat rate for each tier.
If you are looking for a sliding scale calculation, see my article on calculating commission with a tiered rate structure using SUMPRODUCT.
Do NOT Use Nested IFs
A common approach to calculating commissions is using IF statements. With a rate table like this you would have to write multiple IF statements. You basically have to write one IF statement for each tier (row) in the table.
You then have to join all the IF statements into one long and ugly formula. These are called nested IF statements.
I always try to avoid nested IFs when possible because they are difficult to read and understand, and they can be slower for Excel to calculate. If you have thousands of nested IF formulas in your workbook, your calculation time could slow down.
Using VLOOKUP is much easier and cleaner than using nested IF formulas. As you can see with this example, the vlookup allows you to use one formula to calculate the commission payout rate for any given sales amount.
