Attainment Percentage Formula
The calculator uses two formulas depending on the mode you select.
Attainment mode:
Needed amount mode:
- 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 %.
Select Attainment percentage to divide achieved by goal and multiply by 100. The result includes the remaining gap or overage. Select Amount needed for a target percentage to multiply the goal by your desired percentage. This gives the total amount required, not an additional amount.
Reference Tables
The bands below describe shares of a goal. Performance ratings depend on your own scoring rules; these are not universal benchmarks.
| Attainment % | Share of Goal |
|---|---|
| 100% and above | Goal met or exceeded |
| 80% to below 100% | At least four-fifths of the goal, but below the full goal |
| 60% to below 80% | At least three-fifths but less than four-fifths of the goal |
| Below 60% | Less than three-fifths of the goal |
| 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? That depends on your team or instructor's criteria. There is no universal 80% threshold; 100% means the stated goal is met.
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? The achieved value and goal must use the same unit. You may enter dollars, marks, tasks, kilometres or hours, for example. The calculator uses generic units and does not convert units or currencies.
