How it works

  1. 1

    Enter the number of completed work units.

  2. 2

    Enter the total number of work units in the project.

  3. 3

    Optionally set a weight per unit if some units carry more effort or priority.

  4. 4

    The calculator shows your completion percentage and remaining units.

(completed_units * weight_per_unit) / max(total_units * weight_per_unit, 0.0001) * 100

Frequently asked questions

What does 'weight per unit' mean?

It lets you assign a relative importance or effort to each unit. If all units are equal, keep it at 1.

Can I use this for tasks with different sizes?

Yes, adjust the weight per unit to reflect the effort or priority of each unit, making the percentage more accurate.

What if I complete more units than total?

The calculator caps the percentage at 100% effectively, but it will show a value above 100 if you enter more completed than total; it's best to keep completed ≤ total.

Formulas

The math behind this calculator, written out so you can verify the result.

Basic Completion Percentage

Completion % = (Completed Units / Total Units) × 100

Simple ratio of completed work to total work, expressed as a percentage.

Example:

Input: Completed = 30, Total = 50

Calculation: 30 / 50 × 100

Result: 60%

Weighted Completion Percentage

Completion % = (Completed Units × Weight) / (Total Units × Weight) × 100

Each unit is multiplied by a weight to reflect its importance or effort, giving a more accurate progress measure.

Example:

Input: Completed = 10, Total = 40, Weight = 2

Calculation: (10 × 2) / (40 × 2) × 100

Result: 25%

Real-world use cases

Where this calculation shows up in everyday life.

Track project milestones

Monitor how much of a project is done by counting completed tasks or deliverables.

Example: A software project with 50 features, 30 completed.

Weighted task prioritization

Assign higher weights to critical tasks so progress reflects their importance.

Example: High-priority tasks weigh 2, low-priority weigh 0.5.

Team progress reporting

Give stakeholders a clear percentage of overall completion.

Example: Weekly report showing 75% completion.

Tips and common mistakes

Tips

  • Break your project into small, countable units for accuracy.
  • Update completed units regularly to keep the percentage current.
  • Use weights when some tasks take significantly more effort.
  • Combine with remaining units to plan next steps.

Common Mistakes to Avoid

  • Forgetting to include all tasks in total units.
  • Using weights inconsistently across units.
  • Entering completed units greater than total units.

Assumptions and limitations

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
