Estimating time saved for 20 posts a week
The time saved calculator turns a 9-minute-per-post difference into roughly 3 hours saved every week and about 13 hours a month.
Social media calculators
This hub lists every free social media calculator SkedCast publishes in one place: engagement rate, ROI, budget, CPM, agency pricing and margin, plus newer additions for posting frequency, time saved, aspect ratio, follower growth, influencer rates and switching costs. Every calculator shows its formula next to the result and runs entirely in your browser.
How to use this hub
- Pick the calculation you need. Scan the cards below for the calculator that matches your question, from engagement rate to switching cost.
- Open the calculator. Click through to run it — every calculator works standalone with its own inputs and its own page.
- Enter your own numbers. Every calculator computes live from numbers you type in, updating the result as you adjust each input.
- Read the formula alongside the result. Each tool shows the exact formula it used, so the number is reproducible rather than a black box.
- Treat projections and estimates as estimates. A few of these calculators, like follower growth, are explicit projections based on an assumption you provide, not a guarantee.
Worked examples
