Calculators
Planning tools related to journalism & media innovation, with visible assumptions and clearly explained results.
Estimate a planning budget for an animation project from its runtime, production effort, and chosen production scope. The estimate uses a simple per-minute baseline and explicit scope multipliers, so it is a starting model rather than a quote.
Estimate an article's word count by multiplying its paragraph count by the average number of words per paragraph.
Estimate the decimal megabyte size of audio files from their duration, bitrate, and file count. The calculation assumes a constant bitrate and excludes container and metadata overhead.
Calculate the arithmetic mean of up to five values by dividing their sum by the number of values entered. Enter measurements or observations in consistent units.
Estimate the average number of words in each paragraph by dividing a draft's total word count by its number of paragraphs.
Calculate the average number of words in each sentence from a total word count and sentence count. The result is a simple average and depends on consistent counting rules.
Calculate the average number of words on each page by dividing a document's word count by its page count.
Estimate the storage needed for video footage using an uncompressed video data model adjusted by your expected compression ratio. Enter the footage duration, frame dimensions, frame rate, bit depth, and compression ratio. The result is an approximate decimal storage size in gigabytes.
Estimate the number of frames in a video from its duration and frame rate. The result is rounded to the nearest whole frame.
Estimate the duration of a video sequence from its frame count and frame rate. This simple conversion assumes every counted frame plays once at a constant rate.
Estimate the Gunning Fog readability index from a passage’s word count, sentence count, and number of complex words. The score is a readability estimate, not a grade or a judgment of writing quality.
Estimate the total number of words across a set of headlines by multiplying the number of headlines by the average words per headline.
Calculate the percentage of Instagram followers who engaged with a post using likes, comments, saves, shares, and follower count.
Find the median of exactly three numbers by entering each value. The calculator orders the values implicitly and returns the middle value.
Estimate the total character capacity of a newsletter layout by multiplying its number of columns by the character capacity of each column.
Estimate the interview minutes assigned to each reporter by dividing the total scheduled interview time across the reporter team.
Convert a probability entered as a percentage into decimal odds, fractional odds, and the corresponding odds against. This is a mathematical conversion only and does not estimate outcomes or recommend a wager.
Estimate a document's word count from its page count and your chosen average words per page. The estimate assumes the same layout and text density across all pages.
Calculate what percentage one value is of another, with both values entered in the same units.
Calculate the percentage decrease from an original value to a smaller new value.
Calculate the percentage increase from an original value to a new value. Enter positive values in the same units to see the relative change.
Solve a proportion by finding the fourth value in an equivalent-ratio equation. Enter three known values to calculate the missing value using cross multiplication.
Calculate the number of events per 100,000 people from an event count and population. Enter counts measured over the same period and in the same population group.
Compare two quantities as a ratio, simplify it, and scale the equivalent ratio to find a missing value.
Estimate a text's Flesch Reading Ease score from its word, sentence, and syllable counts. Enter counts you have measured; this calculator does not analyze text directly.
Estimate how many minutes it takes to read a piece of writing from its word count and your reading speed.
Estimate the storage capacity needed for audio or video recordings from recording time, bitrate, and a planning allowance. The estimate assumes a constant bitrate and decimal gigabytes.
Calculate an absolute error margin from a reported measurement and a user-supplied percentage. The result uses the same units as the measurement and assumes the percentage applies directly to that value.
Calculate the total pixel count and aspect ratio from a display's width and height in pixels. This arithmetic tool describes the entered dimensions and does not assess image quality or device compatibility.
Estimate a script's spoken duration from its word count, delivery rate, and any manually entered pauses. The result is an estimate because actual speaking pace varies.
Estimate how long a speech or presentation will take by dividing its word count by your speaking rate.
Calculate the population standard deviation for exactly four numeric values. Enter each value to find how spread out the four observations are around their mean.
Estimate total revision time in minutes by multiplying the number of stories by the average minutes spent revising each story.
Calculate user-entered TikTok likes, comments, and shares as a percentage of views. This calculator performs arithmetic only and does not retrieve or verify platform metrics.
Add hours, minutes, and seconds to find a total elapsed duration. Enter the time components and view the result in seconds.
Estimate the finished playback duration of a timelapse from the recording time, capture interval, and playback frame rate. Assumes one frame is recorded at each interval and excludes setup time or dropped frames.
Estimate how many photos a timelapse will capture and the resulting video duration from the capture interval, shooting time, and playback frame rate. Assumes a constant interval and uninterrupted capture.
Estimate typing speed in words per minute from the number of words typed and the time spent typing.
Estimate gross video ad revenue from monetized views and the RPM you enter. The result uses your RPM assumption and is not an earnings prediction.
Calculate a video's numeric width-to-height aspect ratio from its pixel dimensions.
Estimate the average video bitrate needed to fit a video within a target file size, using duration and audio bitrate as inputs.
Estimate compressed video file size from duration, average video bitrate, and audio bitrate. This bitrate-based estimate assumes constant average rates and excludes container overhead and bitrate variation.
Estimate a video's file size from its average bitrate and duration. The estimate uses decimal storage units and excludes container overhead and metadata.
Convert a source clip's frame rate to a target frame rate and estimate the playback duration when its frames are shown at that target rate. Enter the source frame count and both frame rates.
Estimate a video production budget from crew days, editing days, equipment days, and project complexity. This worksheet uses planning rates and a complexity factor you choose, so it is an estimate rather than a vendor quote.
Estimate the total storage required for video files from their duration, bitrate, and number of clips. The estimate uses decimal gigabytes and excludes audio, metadata, and file-system overhead unless included in the bitrate.
Calculate your reading or speaking pace in words per minute from the number of words and elapsed time.
Estimate the number of manuscript pages represented by a word count and your chosen words-per-page assumption.
Estimate ad revenue from monetized views using your estimated playback-based CPM and the share of views that show ads. This worksheet-style estimate excludes other creator income and actual platform adjustments.
Estimate total watch hours from the number of video views and the average time viewers spend watching, expressed in minutes.
