How to use this tool

4 steps · ~1 minute

Each step is a single action — no setup, no sign-up. Outputs are client-side; nothing is uploaded.

Step 01

Pick a mode

Project: enter your sub mix, get total length. Reverse: enter target length, get required sub count.

Step 02

Set the timer rule

Starting timer (minutes) + minutes added per Tier-1 sub. Most subathons use 5 min/T1.

Step 03

Enter the sub mix

T1, T2, T3, and gifted T1 counts. T2 = 2×T1 minutes, T3 = 5×T1 minutes, gifted = 1×T1.

Step 04

Pick a payout split

Twitch Aff (50/50), Partner (70/30), or Kick (95/5). The gross figure applies the split symmetrically.

FAQ · methodology & caveats

Frequently asked.

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

How are higher tiers weighted?

Standard subathon convention: Tier 1 = 1× the base minute rule (default 5 min). Tier 2 = 2× T1 (so 10 min at default). Tier 3 = 5× T1 (25 min). Gifted T1 = 1× T1 (5 min). Bits and tips are not included in this v2 surface — use the v1 page for the full extension model.

What about the cap?

Most marathon subathons set a hard cap to avoid runaway streams (Ludwig 2021 was uncapped and ran 31 days; Kai Cenat's Mafiathons cap around 30 days). Set the cap to 0 or leave blank to disable. The result will show "Capped at Xh" with the uncapped total in the secondary line if you exceed the cap.

Which payout split should I use?

Twitch Affiliate is 50/50 ($2.50 per T1). Twitch Partner is 70/30 ($3.50 per T1) — also reachable via the Plus Program at ≥300 monthly Plus Points. Kick is 95/5 ($4.74 per T1). The gross figure uses your selected split applied symmetrically across T1/T2/T3.

How accurate is the gross revenue number?

It assumes the published creator-side rate. Actual payout differs by sub-tax (varies by country), processor fees (typically -2% net), and the platform's monthly settlement schedule. Treat the figure as gross-before-deductions.

What is "reverse" mode?

Reverse mode solves the other direction: "I want to stream for X hours — how many T1-equivalent subs do I need?" T1-equivalent because Tier 2 counts as 2 of these and Tier 3 counts as 5. So 500 T1 + 100 T2 + 20 T3 = 800 T1-equivalents.

What about sleep / DJ blocks?

The v1 page models sleep hours per 24h to convert broadcast minutes to wall-clock end time. This v2 surface keeps the always-live model; for >24h subathons with planned DJ-mode blocks, use the v1 page.
