Your wall-clock end in 24-hour format (e.g. 22:30 = 10:30 PM your local time).

Step 02

Enter your CCV and category

Average concurrent viewers + the game/category you typically stream. Both feed the fit and bonus scoring.

Step 03

Enter the target schedule

Target start and end times in HH:MM, plus their typical CCV and current game. Times in your local timezone.

Step 04

Read the ranked windows

The result shows the best 30-min raid window with overlap, fit, and category bonuses broken out.

FAQ · methodology & caveats

Frequently asked.

Calculator outputs are estimates. Each Q below names the source data and the assumptions baked in.

How is the acceptance score calculated?

Four dimensions, multiplied. 1) Schedule overlap: minutes of overlap between your 30-min raid window and the target broadcast hours. 2) Last-15-min penalty: 50% deduction if your raid lands inside the target's last 15 minutes. 3) Audience-size fit: 100% if the target CCV is 0.5×-2× yours, 50% if 0.25×-4×, else 0%. 4) Category match: +10% bonus when both streams are the same game.

Why does timing matter so much for raids?

A raid is a goodwill ask. Land it when the target is about to go offline (last 15 min) and you fail the etiquette test — the target can't reciprocate. Land it mid-stream and your viewers find a live host immediately. The calculator surfaces the 30-minute window with the best expected outcome.

What's the right audience-size fit?

Targets between 0.5× and 2× your CCV give the cleanest match. A 10-CCV streamer raiding a 5-CCV target doubles their host's audience and feels welcome. A 10-CCV streamer raiding a 1k-CCV target gets lost in the chat. A 10-CCV streamer hosting a 1-CCV target offers little upside.

Where do I find the target's broadcast hours?

The v1 page autofetches this from Helix VOD data. This v2 surface uses manual input — check the target's recent VOD start/end times on their Twitch channel page, or use their stated schedule.

Does the calculator know if my target is live?

This v2 surface does not — use the v1 page (or Twitch directly) for live status. The calculator scores hypothetical raids against typical broadcast hours.

Can I raid mid-stream targets?

Yes — that's actually the highest-acceptance pattern. Raid 10-30 minutes into the target's session so they have audience momentum and can deliver value to your viewers.
