GPU Mining Profitability Calculator

About the GPU Mining Profitability Calculator

GPU mining remains viable for many altcoins that use memory-hard algorithms designed to resist ASIC dominance. This calculator helps you determine whether mining with your graphics card(s) is profitable by factoring in hash rate, power consumption, electricity cost, and the current mining revenue for your chosen algorithm.

Enter your GPU's hash rate and TDP (or measured power draw), your electricity rate, and the expected revenue per unit of hash power. The calculator shows your daily profit per GPU and lets you scale to multiple cards to see total rig profitability.

GPU mining offers flexibility that ASICs don't — you can switch between algorithms and coins as profitability changes. However, GPUs are less efficient than ASICs for supported algorithms. This calculator helps you find the sweet spot.

Use the result to map token-release or fee scenarios and revisit the model when market conditions, unlock terms, or portfolio assumptions change.

When This Page Helps

GPUs are versatile mining tools with significant resale value, but they're also less power-efficient than purpose-built ASICs. This calculator helps you determine whether your GPU mining operation generates positive returns after electricity costs, and project earnings across multiple cards in a rig.

How to Use the Inputs

1. Enter your GPU's hash rate for the target algorithm.
2. Enter actual power consumption in watts (use monitoring software for accuracy).
3. Enter your electricity rate per kWh.
4. Enter the daily revenue per unit of hash power (from mining revenue sites).
5. Enter the number of GPUs in your rig.
6. Review per-GPU and total rig profitability.

Example Calculation

Tips & Best Practices

• Use actual measured power draw, not the GPU's TDP — mining power is usually lower than gaming peak.
• Undervolting your GPU can significantly reduce power consumption with minimal hash rate loss.
• Keep GPU temperatures below 70°C for longevity; memory temperatures below 95°C for memory-intensive algorithms.
• GPUs retain resale value for gaming, unlike ASICs which become worthless when obsolete.
• Auto-switching software can maximize revenue by mining the most profitable coin at any time.
• Factor in the base system cost (motherboard, CPU, RAM, PSU) when calculating total rig ROI.

GPU Mining Fundamentals

GPU mining uses the parallel processing power of graphics cards to compute hashes. Unlike ASICs, GPUs can mine multiple algorithms, giving miners the flexibility to switch between coins based on profitability. This versatility is their key advantage.

Optimization Techniques

Power efficiency is crucial for GPU mining profitability. Undervolting, adjusting core and memory clocks, and optimizing fan curves can reduce electricity costs by 20-30% with minimal hash rate impact. Use mining-specific BIOS or software profiles for best results.

Building a GPU Rig

A mining rig typically consists of 6-12 GPUs connected to a mining motherboard, powered by one or more high-wattage PSUs. Open-frame cases improve airflow. Budget $200-400 for the base system (motherboard, CPU, RAM, SSD) plus the cost of GPUs and PSU.

Frequently Asked Questions

• Which GPUs are best for mining?

  The best mining GPUs offer the highest hash rate per watt. NVIDIA and AMD each have models that excel at different algorithms. Check current benchmarks for your target algorithm, as performance varies significantly between algorithms.

• Is GPU mining still profitable?

  GPU mining can be profitable for specific altcoins, especially those using algorithms like KHeavyHash, Autolykos, or others that resist ASIC optimization. Profitability depends heavily on your electricity cost — rates under $0.08/kWh are generally needed.

• How much power does a mining rig use?

  A typical 6-GPU mining rig uses 700-1200W total, including GPUs, motherboard, CPU, and fans. The exact amount depends on the GPUs and mining algorithm. Always use a high-quality PSU rated for at least 80% of its capacity.

• Should I undervolt my mining GPU?

  Yes, undervolting is highly recommended for mining. Most GPUs can mine at full hash rate with 20-30% less power by reducing voltage. This improves profitability, reduces heat, and extends GPU lifespan.

• Can I mine and game on the same GPU?

  Technically yes, but mining reduces GPU performance for gaming and increases wear. Most serious miners use dedicated rigs. If mining on a gaming PC, you can mine when not gaming and stop mining when you want to play.

• How long do GPUs last when mining 24/7?

  Well-cooled GPUs running at reasonable temperatures can mine for 3-5+ years. The fans are usually the first component to fail and can be replaced cheaply. Memory chips may degrade faster on memory-intensive algorithms.
