Attainment Percentage Formula
The calculator uses two formulas depending on the mode you select.
Attainment mode:
Attainment % = (Achieved / Goal) * 100
Needed amount mode:
Needed Amount = Goal * (Desired % / 100)
- Achieved: the actual amount produced, scored, or completed.
- Goal: the target you are measured against.
- Attainment %: the share of the goal you have reached.
- Desired %: the attainment level you want to hit.
- Needed Amount: the actual amount required to hit the desired %.
The Attainment tab takes your achieved and goal values, divides them, and multiplies by 100. It also returns the remaining gap (goal minus achieved) or the amount you exceeded the goal by. The Needed amount tab works backward: it multiplies the goal by your target percentage to show what you need to produce.
Reference Tables
The bands below are common defaults used in sales, operations, and academic grading. Adjust them to match your own scoring rules.
| Attainment % | Typical Status |
|---|---|
| 100% and above | Goal met or exceeded |
| 80% to 99% | Solid, on-track |
| 60% to 79% | Underperforming |
| Below 60% | Significant shortfall |
| Goal | Achieved | Attainment % |
|---|---|---|
| 10,000 | 5,000 | 50% |
| 10,000 | 7,500 | 75% |
| 10,000 | 9,000 | 90% |
| 10,000 | 11,500 | 115% |
Example Problems
Example 1: Sales quota. Your quarterly quota is $250,000 and you closed $212,500. Attainment = (212,500 / 250,000) * 100 = 85%. The remaining gap is $37,500.
Example 2: Working backward. You want to hit 90% attainment on a 1,200-task goal. Needed amount = 1,200 * (90 / 100) = 1,080 tasks.
FAQ
Can attainment go above 100%? Yes. Anything above 100% means you exceeded the goal. The calculator shows the overage amount when this happens.
What counts as good attainment? 80% is the common threshold for “on track” in sales and performance reviews, but your team or instructor may use a different cutoff.
Why does the goal need to be greater than zero? Dividing by zero is undefined, so a goal of 0 cannot produce a valid percentage.
Does the unit matter? No. As long as the achieved value and the goal use the same unit, the percentage is the same. The unit selector is only there to label the output.
