SiteKeeper

Free productivity tools

These free calculators turn minutes you type into a longer view of the same habit. The browsing time calculator takes the sites you name and the minutes per day you enter, then shows that guess as hours across a week, a month, and a year. The distraction cost calculator prices the same kind of minutes at an hourly rate you choose, across the workdays you enter, and shows a dollar cost for the week, the month, and the year. Use either page to plan a limit, compare two sites, or check whether a short daily visit is still small once you multiply it out. Nothing on this page is a report of sites you actually opened.

What you are estimating

Both calculators run in your browser. Totals update from the fields on the page: site names, minutes, days, and, on the cost page, a rate or a salary. They do not read your browser history, your open tabs, or visits the SiteKeeper extension may already be recording. You can use them in a private window, on a shared computer, or before you install anything. The numbers you type are not submitted to SiteKeeper. SiteKeeper is privacy-first and never sells or shares your data.

Every result is an estimate. If you type 30 minutes, the yearly hours are those 30 minutes times the days you entered, divided by 60. It is not a measurement of those days. A long Monday and a short Friday only show up if the daily figure you typed already reflects that mix. Sample rows exist so the charts are not empty. They are not an average person, not a published study, and not a claim about how much time people spend online. If a total looks large, read the inputs before you treat the total as a fact. Change the minutes and the total changes with them.

Measured time is a different job. SiteKeeper is a Chrome extension that records time on sites you visit and can block a site when you hit a limit you set. Install it from the Chrome Web Store when you want those minutes from Chrome rather than from a guess. A practical order is to sketch the habit here, use time tracking for a few days, then set website limits on the sites that actually ran long. The calculators stay useful after that. They are the scratch pad. The extension is the record.

What you can do here

  • Roll minutes per day up to weekly, monthly, and yearly hours.
  • Price those minutes at your own hourly rate or at a salary you enter.
  • Pick the hours calculator or the cost calculator for the question you have.
  • Open a Chrome guide when you already know which site you want to cap.

Calculators

Two tools, two questions. One rolls minutes up to hours. The other prices those minutes at a rate you enter.

  • Distraction Cost Calculator

    Estimate the yearly dollar cost of minutes on distracting sites.

    Use when…

    • You bill by the hour and want a yearly dollar figure for a daily news, chat, or video habit at your rate.
    • You have a yearly salary and want that pay turned into a rate across the workdays you count, then applied to the minutes you type.
    • You want the yearly cost of two sites side by side, or the hours and dollars that return if you cut those minutes by a percent you choose.

  • Browsing Time Calculator

    See how minutes per day roll up to hours per week, month, and year.

    Use when…

    • You want a work-year or school-year total for a daily YouTube or Reddit guess, using day counts you choose.
    • You are comparing a five-day habit with a seven-day one before you decide on a limit.
    • You want each site's share of the minutes you typed, on one day view, before you open a block guide.

How we calculate

Both calculators use only the numbers on the form. There is no average user and no lookup of your history. The steps below are the whole method.

Browsing time

Open the browsing time calculator. Enter minutes per day for each site, then days per week and days per year. Those two day fields are separate. The year does not have to equal the week times 52. The page adds the site minutes first.

  • Weekly hours = total minutes per day × days per week ÷ 60.
  • Yearly hours = total minutes per day × days per year ÷ 60.
  • Monthly hours = yearly hours ÷ 12. That spreads the year across 12 months. It is not a four-week month.

The day chart shows the share of each site in the minutes you entered. If those minutes add up to more than 24 hours, the week, month, and year totals still use the full number you typed.

Distraction cost

Open the distraction cost calculator. Enter distracted minutes per workday, an hourly rate or a yearly salary, and workdays per year.

  • Yearly hours = total minutes per workday × workdays per year ÷ 60.
  • Yearly cost = those hours × the hourly rate.
  • Salary mode turns pay into a rate: hourly rate = salary ÷ workdays ÷ 8. The 8-hour day is an assumption for that conversion, not a record of how long you worked.
  • Weekly cost always uses five workdays, even when the year you entered has a different rhythm. Monthly cost = yearly cost ÷ 12.
  • The control labeled Could cut by applies the percent you pick to the yearly hours and the yearly cost. It does not change the minutes already on the form.

If a dollar figure looks high, the minutes or the rate are high. Edit either one and the cost follows.

For minutes recorded from Chrome, see time tracking. To stop a site after a cap, see website limits. The guides below walk through a cap or a block for common sites.

Frequently asked questions

Do these tools read my browser history?

No. Both calculators use only what you type: site names, minutes, days, and, on the cost calculator, a rate or a salary. They do not read Chrome history, open tabs, or records from the SiteKeeper extension. Sample rows are placeholders so the pages are not blank. Replace them with your own guess.

How is an estimate different from measured time in SiteKeeper?

An estimate is arithmetic on the numbers you typed. It is not a log of sites you visited. SiteKeeper, the Chrome extension, records time on sites you actually open in Chrome and can apply a limit you set. Install the extension when you want measured minutes, then compare those minutes with the guess you used here. These calculators do not become a measurement on their own.

Are the numbers I type sent to SiteKeeper?

No. The math runs in your browser, and the numbers you type are not submitted to SiteKeeper. SiteKeeper is privacy-first and never sells or shares your data.

Which calculator should I use?

Use the browsing time calculator when the question is hours: minutes per day rolled up with the days per week and days per year you enter. Use the distraction cost calculator when the question is dollars: distracted minutes priced at an hourly rate, or at a salary spread across the workdays you enter. Hours answer how long. Cost answers what that time is worth at the rate you chose. You can use both on the same guess.

Can I use these calculators without installing the extension?

Yes. Both calculators work in the browser with no install and no account. The extension is for measured time and for limits that block a site after a cap you set. Start here for a quick estimate. Install SiteKeeper when you want Chrome to record real minutes.

A number from a calculator is still a guess. These guides show how to cap or block one site on Chrome after you decide the minutes are too high. Each guide uses SiteKeeper and also lists options that do not require the extension.
