Calculators
Decision-support tools for sizing, cost, capacity, runtime, ownership, and other practical planning questions.

Calculate the percentage of impressions that resulted in clicks by entering total clicks and total impressions.
Estimate customer acquisition cost by dividing total marketing and sales spend by the number of new customers acquired during the same period. Enter costs in one currency and use a consistent period.
Estimate monthly mobile or home network data use from daily activity, entered as average gigabytes per day.
Estimate ideal download time in seconds from file size in decimal megabytes and supplied throughput in decimal megabits per second. This is an arithmetic estimate; actual transfer time varies.
Calculate the percentage of website sessions that result in purchases using your session and order totals.
Calculate the percentage of delivered marketing emails that generated at least one tracked click, using your delivered email count and unique clickers.
Estimate email marketing return on investment from attributed revenue and campaign costs. The result is a percentage based on the inputs you provide and does not establish causation or forecast future performance.
Calculate the percentage of delivered emails that were opened using your delivered and opened counts.
Calculate the percentage of people reached who engaged with a post by dividing total engagements by reach and multiplying by 100.
Estimate transfer duration from file size and effective transfer speed. This assumes a steady rate and decimal units, with 1 GB equal to 1,000 MB and 1 Mbps equal to 0.125 MB/s.
Calculate the percentage change in followers over a selected reporting period using starting and ending follower counts. A positive result indicates growth, while a negative result indicates a decline.
Calculate the percentage of an influencer's audience that engaged with a post using its likes, comments, shares, saves, and follower count. This is an interaction rate per follower, not a measure of unique people reached.
Estimate a starting collaboration fee from audience size, engagement, content deliverables, and usage duration. The estimate is a planning model, not a market quote.
Calculate the percentage of followers who engaged with a post using likes, comments, saves, shares, and follower count.
Calculate the percentage of leads that become customers during a selected reporting period.
Estimate marketing return on investment as a percentage by comparing attributed gross profit before marketing cost with total marketing spend. This simple calculation does not measure revenue multiple or account for other business costs.
Count the characters in a meta description and compare the total with an editable target length. This checker measures character count only and does not evaluate search result display or SEO performance.
Estimate the volume of data transferred by multiplying a steady transfer rate in megabytes per second by a duration in seconds. The result is in megabytes (MB) and assumes the rate remains constant for the full interval.
Estimate the aggregate network capacity needed for a set of simultaneous connections, plus additional overhead capacity. Enter connection counts and rates in megabits per second (Mbps).
Estimate how many seconds it takes to transfer a file over a network using its size in megabytes and the available bandwidth in megabits per second. The estimate assumes a steady connection and excludes protocol overhead and other delays.
Calculate return on ad spend (ROAS) by dividing revenue attributed to advertising by the ad spend. Enter both amounts in the same currency. The result is a revenue-to-ad-cost ratio, not profit or a profitability assessment.
Calculate a display's total pixel count and aspect ratio from its horizontal and vertical pixel dimensions.
Estimate a script's spoken runtime from its word count and delivery pace, with optional time for pauses and visual beats. The estimate assumes a steady average speaking rate.
Estimate the total number of articles a team can produce across a set number of weeks based on writer count and weekly output per writer.
Calculate the average number of articles published per production day from your article count and the number of days covered. This simple rate assumes the period and article count refer to the same workflow and time span.
Calculate observed SEO return on investment for a defined measurement period using attributable gross profit and SEO cost. The result reflects the values and attribution method you provide and does not project future performance.
Estimate a website's share of a defined market's visits by dividing site visits by market visits and multiplying by 100. Use visit counts from the same period and measurement method.
Convert an IPv4 CIDR prefix length into its dotted-decimal subnet mask and calculate the corresponding address count. This arithmetic result does not identify usable host addresses or network assignments.
Calculate the percentage of TikTok video views that resulted in likes, comments, shares, or saves. Enter the total interactions and views for the same video or reporting period.
Calculate the percentage of delivered marketing emails that resulted in unsubscribes for a campaign or reporting period.
Estimate how long a file will take to upload from its size and your connection's upload speed. The estimate assumes a steady speed and excludes protocol overhead and interruptions.
Calculate observed uptime as a percentage from total monitoring time and recorded downtime. This simple availability calculation assumes both values cover the same period and does not predict future service reliability.
Calculate the observed average total bitrate of a video file in megabits per second from its decimal file size and duration. This arithmetic estimate includes all data in the file, not just the video stream.
Estimate a video's approximate file size from its average bitrate and duration. The estimate uses decimal megabytes and assumes the bitrate stays constant for the full video.
Estimate the storage required for video files from recording duration, bitrate, number of cameras, and recording days. The estimate uses decimal gigabytes and assumes a constant bitrate with no extra container or filesystem overhead.
Calculate the percentage change in website traffic between two comparable periods using their session totals.
Estimate the ideal time in seconds to transfer a file over a WiFi connection from its size in megabits and the connection speed in megabits per second.
Use your own inputs to calculate the result for wifi link budget.
Estimate YouTube advertising cost from impressions and cost per thousand impressions (CPM). Enter the campaign's total impressions and CPM to calculate the estimated media cost. This simple model assumes the full impression count is billable at the entered CPM and excludes other fees.
Estimate monthly YouTube ad revenue from views and an assumed RPM. This simple estimate does not access channel data or account for every factor that affects actual earnings.
