Commission and Retainer
Salespeople are paid a commission (a percentage of sales) or a retainer (a fixed weekly income). The more sales that a salesperson makes, the greater is their income.
Useful rules are:
- Commission = Percent Commission × Sales
- Total Income = Commission + Retainer
- Sales = Commission × 100 ÷ Percent Commission
Example One - Commission
Salesman Sam earns 5% of whatever he sells. If he sells goods worth $4000, what commission does he receive?
Answer:
Commission
= Percent Commission × Sales
= 5% of $4000
= 5⁄100 × $4000
= $200
Example Two - Commission and Retainer
Salesman Sue earns a retainer of $700 per week in addition to a commission of 3%. How much does she earn for selling goods worth $20000.
Answer:
Commission
= Percent Commission × Sales
= 3% × $20000
= $606
Total Income
= Commission + Retainer
= $600 + $700
= $1300
Example Three - Finding the Original Sales
A salesperson works on a commission of 5% only. If she earns $400 commission, what were the original sales?
Answer:
Sales
= Commission × 100 ÷ Percent Commission
= $400 × 100 ÷ 5
= $8000
