Time Spent on Email Calculator
Find out how much time you spend on emails daily, monthly, and until retirement. Discover alternative activities you could do with the time saved.
Emails are an essential part of modern work life, but they can consume a surprising amount of your day. According to research, the average employee receives over 100 emails per day and checks their inbox dozens of times. Between reading, responding, and the time it takes to refocus after each interruption, email can take up several hours of your workday without you even realizing it.
Our Time Spent on Email Calculator helps you measure exactly how much time you dedicate to email management. Simply enter your email habits and we calculate your daily, yearly, and lifetime email time. Discover what you could accomplish with that time and consider how even a small reduction can lead to meaningful gains in productivity and well-being.
How Email Time Adds Up
The calculation considers three main components. First, reading time depends on how many emails you receive and how thoroughly you read them. A quick glance takes about 1.5 seconds while careful reading can take 20 seconds or more per email. Second, response time covers the emails you reply to and the average time each response takes. Third, recovery time accounts for the 64 seconds it typically takes to refocus after each inbox visit, based on research by Jackson, Dawson, and Wilson published in the Journal of Systems and Information Technology.
When you add these together, a person receiving 50 emails a day who checks their inbox 10 times and responds to half of them at 2 minutes each spends roughly 90 minutes daily on email. That adds up to over 380 hours per year the equivalent of more than 9 full work weeks.
Alternative Activities for Your Saved Time
The calculator also shows what you could do with the time you save by reducing email time. Based on your weight and the Metabolic Equivalent of Task (MET) values, we estimate calories burned through activities like walking, jogging, cycling, and running. You can also see how many books you could read or TV episodes you could watch with your reclaimed time. For example, saving just 30 minutes per day on email could let you read over 30 books or watch more than 120 TV episodes per year.
Tips to Reduce Email Time
Consider these strategies to cut down on email overhead. Be concise in your messages use bullet points and clear subject lines. Batch your inbox checks to set periods rather than reacting to every notification. Unsubscribe from newsletters you no longer read. Use collaboration tools like Slack or Trello for quick communications instead of email chains. Each small change adds up to significant time savings over weeks and months.
Frequently Asked Questions
How is the recovery time calculated?
Each time you check your inbox, it takes about 64 seconds to refocus on your previous task. This is based on research from the Journal of Systems and Information Technology which studied the cost of email interruptions in the workplace. We multiply this by the number of times you check your inbox per day.
What is MET and how do you calculate calories?
MET stands for Metabolic Equivalent of Task, a standard measure of energy expenditure. One MET is the energy you burn at rest. Walking briskly is about 4 METs, jogging is about 7 METs, and running is about 10 METs. Calories burned per minute = (MET x 3.5 x weight in kg) / 200.
How many books could I read with my saved email time?
We estimate based on an average reading speed of 250 words per minute and an average book length of 70,000 words. If you save 30 minutes per day on email, you could read roughly 39 books per year.
Why do you use 260 working days per year?
We use 260 working days which represents 52 weeks at 5 days per week. This reflects a standard full-time work schedule excluding weekends, giving a more accurate picture of work-related email time.
Can I calculate email time for personal use too?
Yes. While the defaults are geared toward workplace email habits, you can adjust the numbers to match personal email usage. Simply enter your personal email counts and use your actual age and desired retirement age to see personal lifetime estimates.
What if I am already retired or close to retirement?
The calculator handles this gracefully if your retirement age is at or below your current age, the retirement section shows Not applicable and focuses on your current annual email time instead.
How accurate are the calorie estimates?
Calorie estimates use standard MET values from the Compendium of Physical Activities. Actual calories burned depend on many factors including your fitness level, metabolism, terrain, and intensity. Use the values as a general guideline for comparing activities rather than precise measurements.
