Payback
Formula
The day the machine has repaid itself at current revenue.
Variables
| Symbol | Name | Unit | Description |
|---|---|---|---|
| C | Hardware | $ | Box cost |
| π | Daily profit | $/d | Net per day |
Explanation
Payback clock on the hardware.
Step-by-Step Calculation
Follow each step to understand how the result is calculated from your inputs.
Daily profit = revenue − electricity
Break-even days = hardware ÷ daily profit = $4,000 ÷ $1.28
Annual ROI = daily profit × 365 ÷ hardware

Scenario
The mining break-even calculator run on the values above, showing the full calculation path.
Inputs
Calculation
1. Daily profit = revenue − electricity → $1.28 2. Break-even days = hardware ÷ daily profit = $4,000 ÷ $1.28 → 3,114 days 3. Annual ROI = daily profit × 365 ÷ hardware → 11.72%
Result
Break-Even: 3,114 days
Interpretation
Pays back in ~3,114 days before difficulty drift.
Understanding Your Result
Your Result: Break-Even: 3,114 days
What This Means
Payback clock on the hardware.
Why It Matters
Pays back in ~3,114 days before difficulty drift.
Professional Interpretation
Pays back in ~3,114 days before difficulty drift.
How this is calculated
The day the machine has repaid itself at current revenue.
What drives the result
Daily coins ≈ (your hashes ÷ network hashes) × blocks per day × block reward. Revenue = coins × price × (1 − pool fee). Profit = revenue − power cost − other costs. Payback = hardware ÷ daily profit.
Recommendations
- •Under ~400 days is strong for ASICs.
- •Difficulty growth lengthens real payback — add margin.
Educational Content
Introduction
Mining turns electricity and hardware into coins. Revenue follows hashrate share of network difficulty times coin price; profit subtracts power and pool costs. Difficulty retargets roughly every two weeks, so every figure here is a snapshot.
Concept Explanation
Daily coins ≈ (your hashes ÷ network hashes) × blocks per day × block reward. Revenue = coins × price × (1 − pool fee). Profit = revenue − power cost − other costs. Payback = hardware ÷ daily profit.
Applications
Benefits
- •Difficulty-aware revenue math
- •Power-first cost view
- •Payback and ROI on one page
Limitations
- •Difficulty and price move constantly
- •Pool luck and downtime approximated via uptime
- •Firmware efficiency gains not modeled
Best Practices
- •Re-run after each difficulty epoch
- •Add 5–10% for cooling and PSU loss
- •Model the next halving before buying hardware
Common Misconceptions
Practical Tips
- •Model halving cuts before buying.
