30 evergreen posts, 5 recycled per week
30 ÷ 5 = a 6-week cycle, or 42 days, before any single post repeats.
Recycle social media posts: interval calculator
How often should you recycle social media posts? This turns an evergreen post pool size and a weekly posting frequency into the real interval before any one post comes back up: weeks per cycle = pool size ÷ posts published per week. This is real scheduling math, the same logic behind SkedCast’s own recycle feature, computed here from scratch for whatever pool size and frequency you type in.
Calculate your recycle interval
How many distinct evergreen posts you rotate through.
How many of your weekly posting slots are filled from that pool.
42 days
≈ 6 weeks per cycle — roughly 8.7 times a year.
Formula
Weeks per cycle = pool size ÷ posts per week; days = weeks × 7.
How to use the recycle interval calculator
- Enter your evergreen pool size. Type how many distinct evergreen posts you rotate through.
- Enter your weekly recycle frequency. Type how many of your weekly posting slots come from that pool.
- Read the interval in days and weeks. See exactly how long before an individual post repeats.
- Adjust your pool size if needed. A shorter interval than you want means growing the evergreen pool.
Worked examples
A smaller pool repeats faster
The same 5-per-week frequency with only 15 evergreen posts instead gives a 3-week (21-day) cycle — half the pool, half the interval.
Recycle social media posts: FAQ
- What is an "evergreen" post?
- Content that stays relevant over time and can be reposted periodically, unlike a time-sensitive announcement or a dated promotion.
- How is the interval in days computed?
- Weeks per cycle multiplied by 7 — a real, exact conversion once the pool-size-divided-by-frequency weeks figure is known.
- What if my interval comes out as a fraction of a week?
- That’s normal and expected — a pool that doesn’t divide evenly by your frequency gives a fractional-week (and whole-day) interval, shown as-is.
- Does this calculator store my numbers?
- No — the calculation happens entirely in your browser as you type, and nothing is uploaded or saved.
- Does SkedCast have a real recycle feature?
- Yes — SkedCast’s own product recycles evergreen posts on a schedule, emitting a real "post.recycled" webhook event each time one goes out.
- How big should my evergreen pool be?
- Large enough that the computed interval feels natural for your audience — this calculator shows you the real interval so you can judge that for your own pool size.
