> The time spent on email calculator estimates how much of your day goes on email – checking, reading and replying – and how many working days and years that adds up to before retirement.

## Inputs

- Emails received per day
- Inbox checks per day
- Reading style
- Emails you reply to
- Minutes per reply
- Working days per year
- Years until retirement

## Results

- Time on email per day
- Hours per week
- Hours per year
- Working weeks per year (40 h)
- Years of working time until retirement

## Formula

```
Daily time = checks × refocus time (≈ 64 s) + emails × reading time + emails × reply rate × minutes per reply
Yearly hours = daily time × working days
```

## Explanation

Research on workplace interruptions suggests it takes around a minute to refocus after checking email, and knowledge workers check their inboxes dozens of times a day. Batching email into a few sessions and replying only when needed can free several hours a week.

### How to use the Time Spent on Email Calculator

- **Emails received per day**
- **Inbox checks per day**
- **Reading style**
- **Emails you reply to**

- **Working days per year**
- **Years until retirement**

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

### How it works

Enter how many emails you receive and how often you check, how you read them, how many you answer and how long a reply takes, plus your working days a year and years until retirement.

### 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.

### What each result means

- **Time on email per day** = ([Inbox checks per day]×64 + [Emails received per day]×[Reading style] + [Emails received per day]×[Emails you reply to]÷100×[Minutes per reply]×60)÷3600
- **Hours per week** = [Time on email per day]×5
- **Hours per year** = [Time on email per day]×[Working days per year]
- **Working weeks per year (40 h)** = [Hours per year]÷40
- **Years of working time until retirement** = [Hours per year]×[Years until retirement]÷([Working days per year]×8)

## Worked example

Inputs — Emails received per day: 80; Inbox checks per day: 30; Reading style: Read normally (11 s); Emails you reply to: Some (25%); Minutes per reply: 3; Working days per year: 230; Years until retirement: 25.

Results — **Time on email per day = 1 h 47 min**; Hours per week = 8.9; Hours per year = 409; Working weeks per year (40 h) = 10.2; Years of working time until retirement = 5.6.
