Variable rates applied to accumulated results

[leebauman]

Hello! In need of assistance to build functional tool to help sales agents track monthly commissions. The commission rate is applied to monthly sales and the rate increases as accumulated annual sales reach specified thresholds. I'm having trouble entering formulas in the "Monthly Incentive" column which generate accurate results. I appreciate any assistance!

Hi,

Can you clarify, for the month of October, where the cumulative is 2,650,000, is the incentive to be paid 250,000 at .05%, and 150,000 at .63%
Or, all 400,000 at .63%

Hello, for October, the first $249,999 would be paid at the .05% rate (up to the $2.5M cumulative amount) and the remaining $150,001 would be paid at the .63% rate.

Same logic for December...first $599,999 paid at the .63% rate and remaining $150,001 paid at the .88% rate.

Thanks for the response!

With some slight adjustment to your setup.

You can use E7 formula copied down, and ignore my Column F,
Or, setup F2:F4 as shown, and use F7 formula copied down.
