About this calculator
The calculator determines your weekly post count per platform using the formula: posts = floor(floor((availableHours × 60) / (timePerPost × platforms)) × engagementLevel). First, your total available minutes per week (availableHours × 60) are divided by the time one post costs across all your platforms (timePerPost × platforms), giving the number of posts you can produce and publish on every platform. The floor() function keeps whole posts only. That capacity is then scaled by the target engagement level: Maintain Presence (0.7) uses 70% of your capacity and leaves a buffer for ideation, editing and community management; Steady Growth (1.0) uses all of it; Rapid Growth (1.4) asks for 40% more posts than your stated hours cover, so it is only reachable if you batch, template or repurpose content (or add hours).
How to use
Assume you have 10 hours per week, each post takes 30 minutes to create, you manage 3 platforms, and you choose Maintain Presence (0.7). Step 1 — convert hours to minutes: 10 × 60 = 600 minutes. Step 2 — calculate time cost per post across platforms: 30 × 3 = 90 minutes. Step 3 — divide: 600 / 90 = 6.67, floor to 6 posts. Step 4 — apply the engagement level: 6 × 0.7 = 4.2, floor to 4. Result: 4 posts per week on each platform, leaving time for engagement and planning. With Steady Growth (1.0) the result is 6.
Frequently asked questions
How many times per week should you post on social media for maximum growth?
Optimal posting frequency varies by platform: Instagram rewards 4–7 posts per week, LinkedIn peaks at 3–5, while TikTok favors daily or near-daily posting. However, consistency and quality outweigh raw volume across all platforms. This calculator helps you find a frequency you can sustain given your real-world time constraints, which is more effective long-term than an aggressive schedule you cannot maintain.
Why does managing more platforms reduce the number of posts this calculator recommends?
Each additional platform multiplies the time cost per content piece because posts must typically be reformatted, resized, and re-captioned to fit different audience expectations and aspect ratios. The formula divides your available time by timePerPost × platforms, meaning adding a fourth platform to a three-platform strategy reduces your output by 25%. Batching content creation and using cross-posting tools can help, but some platform-specific customization time is unavoidable.
What does the target engagement level input mean in the posting schedule calculator?
The target engagement level scales how much of your production capacity you plan to use. Maintain Presence (0.7) publishes 70% of what your hours allow and reserves the rest for ideation, editing and community management, which often yields better results than maximizing raw post count. Steady Growth (1.0) uses your full capacity. Rapid Growth (1.4) plans 40% more posts than your hours cover, which only works if you batch-produce, reuse templates or repurpose content across platforms; otherwise add hours.
