Commission Calculator
Enter the sale amount and the commission rate as a percent. The calculator returns the commission earned and the net to the seller, which is the sale amount minus the commission. Tiered takes up to 10 tiers, with each rate on its own slice or the rate reached on the whole sale. Split shares the commission between two sides, then your side between you and your broker or team.

The commission formula
Commission = Sale amount × rate ÷ 100 · · · Net to seller = Sale amount − Commission · · · You keep = Commission × your side's share × your split
The rate is the percent you enter, so 5 means 5%. The same rate applies to every dollar of the sale. The net to seller is what remains of the sale amount after the commission comes out. The calculator rounds the commission to the cent and takes that figure off the sale, so the two results add up to the sale amount. In Tiered, each line is rounded to the cent and the total is their sum. In Split, your side and your own part are each rounded to the cent, and the other side and the broker get the remainder, so the parts add up to the total commission. A sale exactly at a tier limit belongs to the tier that ends there.
Worked example
A $10,000 sale at 5% earns a $500.00 commission and leaves $9,500.00 for the seller. An $80,000 sale at 6.5% earns $5,200.00, and the seller keeps $74,800.00. In Tiered, with 5% up to $50,000 and 7% above it, an $80,000 sale earns $2,500.00 plus $2,100.00, or $4,600.00, an effective rate of 5.75%. With the rate reached on the whole sale, it earns 7% of $80,000, or $5,600.00. In Split, a $400,000 sale at 5% is a $20,000.00 commission. A 50% share for your side is $10,000.00, and a 70% split of that leaves you $7,000.00 and your broker $3,000.00.
Frequently asked questions
How do I work out a tiered commission?
Choose Tiered, enter the sale and each tier's upper limit and rate. The last tier has no limit. At 5% on the first $50,000 and 7% above it, an $80,000 sale gives $2,500.00 plus $2,100.00, or $4,600.00. The table under the result shows each line, and each one equals the flat rate mode run on that slice.
Which tier method does my plan use?
Your pay plan says, and the calculator cannot tell. Under Each rate on its own slice, a higher rate pays only on the sales above the limit. Under Rate reached on the whole sale, crossing a limit raises the rate on every dollar, so one more sale can add a jump. On the example, the two methods give $4,600.00 and $5,600.00. If your plan counts sales over a month or a quarter, enter the total for that period.
How do I work out a commission split?
Choose Split and enter the sale, the total rate, your side's share and your split of that side. Enter 100 for a share nobody else takes. A 60% share of a 5% commission on a $10,000 sale, with 100 for your split, shows You Keep $300.00. The percentages come from your own agreement, and the calculator assumes none. It has no field for flat fees or a cap, so subtract those from You Keep yourself.
What is a draw against commission?
An advance paid against commissions you have not earned yet. Your pay plan says whether you owe back the difference when later commissions do not cover the draw. The calculator does not track draws, so subtract one from Commission Earned yourself.
How are commissions taxed?
IRS Publication 15 for 2026 lists commissions as supplemental wages. An employer can withhold federal income tax on them at a flat 22% if it withheld from your regular wages this year or last year. Once your supplemental wages for the year pass $1 million, it must withhold 37% on the excess. State tax and FICA come on top. Commission Earned is the amount before any tax.
What can I enter?
A sale amount from 0 to 1 trillion and a rate from 0% to 100%, with decimals in either. An empty field or a rate above 100% gets a message and no result. Tier limits have to rise from one tier to the next. The currency selector changes the symbol only, because a percent works the same in any currency.
