Enter your workflow parameters for a precise monthly estimate of R2 API operations consumed by Secure-Smart-Sync. All calculations use the exact per-operation model from the plugin's sync engine.
How many devices run the plugin with the same vault.
Hours Obsidian is open and you are actively writing. The rest (24 − active) is idle polling at 30 s intervals.
How many times per day the idle debounce fires and triggers a sync on one device. ~5 per active hour is a typical estimate.
Average number of files uploaded or downloaded per sync event. Light: 2 · Moderate: 3 · Heavy: 5+
Total files in your vault. Affects LIST cost — R2 paginates at 1 000 objects, so a 5 000-file vault costs 5 LIST ops per sync walk.
