Last updated: 2026-10-25

> The grade calculator converts points scored on a test or assignment into a percentage and a letter grade on the common U.S. scale, and shows how many points you missed.

## Inputs

- Points earned
- Total points

## Results

- Score
- Points missed

## Formula

```
Grade % = points earned ÷ total points × 100
```

## Explanation

Teachers use different scales, but percentages make any test easy to compare.

### How to use the Grade Calculator

- **Points earned**
- **Total points**
- Want to work backwards? Type a value into **Score** and **Points earned** is calculated for you.

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Divide the points earned by the points possible and multiply by 100.

### Tips

- Track a typical week before planning – real figures beat estimates.
- Break big tasks into smaller pieces and plan buffer time for interruptions.
- Re-run the numbers when your inputs change so plans stay realistic.
- Use results as a guide for decisions, not as a precise prediction.

### Common mistakes to avoid

- Counting calendar days when the deadline is in working days (or the reverse).
- Forgetting breaks, setup and handover time.
- Assuming every day is as productive as your best day.
