Running a subathon without knowing your numbers is a gamble. This free Twitch subathon calculator tracks your final timer clock and calculates your exact net take-home pay after Twitch’s platform splits, processing fees, moderator costs, and income tax.
Every sub, bit, tip, and sponsorship you earn affects both how long you stream and how much you actually pocket. This tool shows you both figures in real time, before and after your event goes live.
How Twitch Subathon Revenue Actually Works
Most streamers focus on hype during a subathon but miss the financial picture entirely. A T1 sub at $4.99 does not put $4.99 in your bank. By the time Twitch takes its cut, payment processors deduct their fee, and you account for staff payouts, the real number is significantly lower.
The timer side is just as layered. Every subscription tier, Bits donation, and direct tip adds a different number of minutes to your clock. Without mapping these rules before going live, you risk running far longer (or shorter) than planned. For streamers exploring broader monetization strategy, the Brand Sponsorship Package Builder is a strong companion tool for pricing your subathon sponsorship slots accurately.
The Subathon Revenue Formula (and What Twitch Actually Takes)
The calculator works through two parallel engines: a time engine and a revenue engine.
Time Engine: Final Timer = Start Time Base + (T1 Subs x mins) + (T2 Subs x mins) + (T3 Subs x mins) + (Bits / 100 x mins) + (Tips / $1 x mins)
In Capped mode, the Final Timer cannot exceed your set Max Time Cap. In Uncapped Marathon mode, the clock runs freely with no ceiling.
Revenue Engine: Gross Revenue = (T1 + T2 + T3 Sub Revenue) + (Bits Value) + Direct Tips + Sponsorships
Net Take-Home Pay = Gross Revenue - Twitch Sub Split - Payment Processing Fee - Moderator Payouts - Estimated Income Tax
Twitch offers two sub revenue split tiers. Standard Affiliates and most Partners receive a 50/50 split, meaning Twitch keeps 50% of every subscription. Select Partners with negotiated contracts receive a 70/30 split, keeping 70% of each sub. Bits are valued at $0.01 per Bit, but Twitch retains a margin on Bit purchases made by viewers.
When This Calculation Doesn’t Apply: If you are on a custom Twitch Partner contract with non-standard revenue terms, or if your channel uses third-party sub gifting tools with different fee structures, the platform split figures may not reflect your actual agreement.

Standard Subathon Revenue Variables by Tier and Split Type
| Variable | Standard (50/50) | Plus/Partner (70/30) |
|---|---|---|
| T1 Sub ($4.99) – Streamer Share | ~$2.50 | ~$3.49 |
| T2 Sub ($9.99) – Streamer Share | ~$5.00 | ~$6.99 |
| T3 Sub ($24.99) – Streamer Share | ~$12.50 | ~$17.49 |
| Bits (per 100 Bits) | $1.00 | $1.00 |
| Payment Processing Fee (typical) | 2-3% | 2-3% |
| Direct Tips (via third-party) | 100% (minus processor) | 100% (minus processor) |
Figures are approximate. Actual payouts may vary by region and Twitch payout schedule.
A Real Subathon: Running the Numbers for StreamerX
Say StreamerX plans a subathon starting with a 12-hour base time and sets a Max Time Cap of 72 hours (Capped mode).
During the event, they receive:
- 20 T1 subs, 10 T2 subs, 100 T3 subs (timer adds 30 mins per T1 sub)
- 25,000 Bits (5 mins added per 100 Bits)
- $500 in direct tips (5 mins per $1 tip)
- $5,000 in sponsorships
- 14 hours slept / AFK
Time Calculation:
- Subs add: (20 x 30) + (10 x 30) + (100 x 30) = 3,900 mins = 65h 0m (this gets capped)
- Bits add: (25,000 / 100) x 5 = 1,250 mins = 20h 50m
- Tips add: (500 / 1) x 5 = 2,500 mins = 41h 40m
- Total Time Added: 5h 32m 30s (after cap is applied at 72h total)
Revenue Calculation (50/50 split, 20% tax, $200 mod payout):
- Gross Revenue: $8,444.60
- Less Twitch Sub Split and Fees: -$1,362.30
- Less Estimated Taxes (20%): -$1,416.46
- Less Moderator Payouts: -$200.00
- Net Take-Home Pay: $5,465.84
Net Earnings Per Hour (Total): ~$313/hr. Active Earnings Per Hour (No Sleep): ~$1,554/hr.

Subathon Planning Mistakes That Cost Streamers Real Money
Setting timer rules too generously without modeling the cap. Many streamers set 30 minutes per T1 sub, receive an unexpected sub train of 500 subs, and suddenly face a 10-day uncapped stream they never budgeted for. Always model your worst-case timer scenario first.
Ignoring the AFK / sleep hours variable. Active earnings per hour (no sleep) can be 4 to 5 times higher than total earnings per hour when sleep is factored in. Knowing this ratio helps you schedule sleep breaks without killing your per-hour rate.
Forgetting withholding tax. A $5,000 gross subathon may realistically net $3,200 after a 30% federal withholding rate for US-based streamers. The IRS treats streaming income as self-employment income, subject to both income tax and self-employment tax. The IRS Self-Employment Tax guidance covers exactly what applies to your situation.
Not accounting for mod and staff payouts. If you pay moderators, editors, or a stream manager during the subathon, these costs come directly out of your gross. Model them before the event, not after.
If you are also running paid API tools or AI-powered content during your subathon production pipeline, the AI Video API Cost Estimator can help you factor those operational costs into your overall event budget.
How to Use the Twitch Subathon Clock & Revenue Tracker
The tool opens in Capped Subathon mode by default. Switch to Uncapped Marathon using the tab at the top if your stream has no time ceiling.
Left Panel (Event Performance & Baseline):
- Enter your Start Time Base in hours (e.g., 12 hrs)
- In Capped mode, set your Max Time Cap (e.g., 72 hrs) – this field appears in red and locks the timer ceiling
- Enter your Subscriptions Received across T1, T2, and T3 fields
- Add Total Bits Received, Direct Tips / Donos, Sponsorships / Bounties, and Hours Slept / AFK
Right Panel (Timer Rules & Economics):
- Set your Timer Configuration: minutes added per T1 Sub, per 100 Bits, and per $1 Tip
- Select your Streamer Sub Revenue Split (50/50 Standard or 70/30 Plus/Partner)
- Enter your Avg T1 Sub Price and Payment Processing Fee %
- Add Moderator/Staff Payouts under Expenses & Deductions
- Check Estimate Income / Withholding Tax and enter your effective tax rate if needed
Currency Settings:
- Set your Base Pricing Currency (default is USD)
- Use Convert Take-Home Payout To to display your net pay in a different currency (AED, AUD, CAD, EUR, GBP, SGD, and more are available)
Hit Calculate Subathon Output. The results display your Final Timer Clock, Net Take-Home Pay, a full Time Breakdown and Financial Breakdown, net earnings per hour, and a Next Milestone Scenario showing how many additional subs you need to hit your next time or revenue target.

Twitch Subathon Calculator FAQs
What is the difference between a Capped Subathon and an Uncapped Marathon?
A Capped Subathon has a hard maximum time limit you set in advance. No matter how many subs or Bits come in, the timer cannot exceed that cap. An Uncapped Marathon has no ceiling, so every sub, Bit, and tip keeps adding time indefinitely until you manually end the stream.
How does Twitch calculate how much a streamer earns per subscription?
Twitch splits subscription revenue with the streamer based on their partnership tier. Standard Affiliates and most Partners keep approximately 50% of each sub’s face value. Select Partners with negotiated deals keep 70%. A T1 sub at $4.99 earns roughly $2.50 under a standard split, before payment processing fees are deducted.
Does this calculator account for income tax on Twitch earnings?
Yes. Check the Estimate Income / Withholding Tax box in the right panel and enter your effective tax rate as a percentage. The tool then deducts that estimated tax from your gross earnings and includes it as a line item in the Financial Breakdown. This gives you a net take-home figure that reflects real after-tax income.
