Use this commission calculator to estimate your earnings from a flat rate, tiered plan, or quota-based plan, with splits, returns/chargebacks, caps, and draw recovery. You will also see a tier-by-tier breakdown and your effective commission rate for the pay period you pick.
Advanced options
How to use our Commission Calculator
- Select your Commission plan type (Flat rate, Tiered, or Quota/attainment) and your Pay period.
- Choose your Sales input method: Total sales for one number, or Deal list if you want to add multiple deals.
- Enter your sales amount(s). If you use Deal list, add each deal amount and the calculator will sum them into Total sales.
- (Optional) Open Advanced options and pick your Commission basis (Gross or Net). If you choose Net, enter Total costs for the same period.
- (Optional) Enter Returns or chargebacks if refunds or cancellations reduce what you get paid on.
- If you picked Flat rate, enter Commission rate (percent).
- If you picked Tiered, set Number of tiers and Tier method, then enter each tier end and rate (the last tier can be open-ended).
- If you picked Quota/attainment, enter your Quota plus the below-quota rate and accelerator rate.
- (Optional) Add split settings, a commission cap, a recoverable draw, base pay, and an optional withholding percent.
- Click Calculate to see commissionable amount, commission at each step (split, cap, draw), total earnings with base pay, and any annual projection.
Definitions
Commissionable amount: The dollar amount your commission percent is applied to after adjustments like returns/chargebacks (and possibly costs if you use net/profit basis).
Flat rate commission: One percent rate applied to the full commissionable amount.
Tier (commission tier): A range of sales with its own commission percent, such as 0 to 10,000 at 5%, then 10,000 to 25,000 at 7%.[1]
Marginal (stacked) tiers: Each rate applies only to the part of sales inside that tier.
Retroactive tiers: Once you reach a tier, one rate applies to all sales for the period (based on your highest tier reached).
Quota and attainment: Quota is your sales goal for the period; attainment is sales divided by quota (shown as a percent).[2]
Accelerator rate: A higher percent rate that applies after you pass a threshold (often after 100% of quota).
Split: Sharing commission with other people (equal split or a custom percent share).
Draw (recoverable): An advance that may be subtracted from future commissions until it is repaid.
Clawback / chargeback: When commission is reduced later because a deal is refunded, canceled, or not collected.
Methodology
1) Inputs the calculator uses
The calculator starts with Total sales for the selected pay period. It then builds a commissionable amount (the base dollars used for commission) and applies the plan math you pick (flat, tiered, or quota/attainment) as described in common commission plan structures.[1][2]
2) Commissionable amount (basis and adjustments)
commissionable_amount = total_sales - returns_chargebacks
If Commission basis is Net (profit), costs are required.
commissionable_amount = (total_sales - total_costs) - returns_chargebacks
Returns/chargebacks default to 0 when blank. Negative commissionable amounts are allowed and mean refunds/costs were larger than sales for the period.
3) Plan commission (before split, cap, draw)
Flat rate
gross_commission = commissionable_amount * (flat_rate_percent/100)
Tiered plan: marginal (stacked)
gross_commission = sum over tiers i of max(0, min(commissionable_amount, upper_i) - lower_i) * (rate_i/100)
last_tier_part = max(0, commissionable_amount - lower_last) * (rate_last/100)
The Tier breakdown output lists each tier portion and its commission so you can check the math.
Tiered plan: retroactive
applied_rate = rate_of_highest_tier_reached
gross_commission = commissionable_amount * (applied_rate/100)
Quota/attainment plan (two-segment)
attainment_percent = (total_sales / quota_amount) * 100
gross_commission = min(total_sales, quota_amount) * (below_rate/100) + max(0, total_sales - quota_amount) * (accelerator_rate/100)
4) Split, cap, and draw recovery (in that order)
Split factor depends on Split commission with others?
split_factor = 1 (no split), or 1/split_count (equal), or your_split_percent/100 (custom)
commission_after_split = gross_commission * split_factor
Cap is optional. A cap is treated as a maximum, not a minimum. If commission is negative, the calculator keeps it negative (it does not clamp to zero).
commission_after_cap = commission_after_split (if cap blank)
commission_after_cap = min(commission_after_split, commission_cap) (only when commission_after_split is non-negative)
Draw recovery is optional and modeled as a simple single-period subtraction (it does not track rolling balances across months).
commission_after_draw = commission_after_cap (if draw blank)
commission_after_draw = commission_after_cap - draw_amount (if draw entered)
5) Totals, effective rate, projection, and take-home
Final commission is commission_after_draw when a draw is entered; otherwise it is commission_after_cap.
total_earnings = base_pay + final_commission
effective_rate_percent = (final_commission / commissionable_amount) * 100
If commissionable_amount is 0, effective rate is shown as N/A to avoid divide-by-zero.
Annual projection (shown only if enabled): multiplier is 12 for Monthly, 4 for Quarterly, and 1 for Annual.
annualized_total = total_earnings * multiplier
Optional take-home estimate (shown only if withholding percent is provided):
estimated_take_home = total_earnings * (1 - withholding_percent/100)
6) Validation and safe handling
The calculator blocks calculation with a clear error message if required percent fields are blank, quota is not greater than 0 in quota mode, net/profit basis is selected without costs, tier bounds are not increasing, or split settings are not valid (like equal split with fewer than 2 people, or custom split outside 0 to 100).
