Understanding PC & Mining Rig Electricity Costs in Bulgaria

For PC builders, gamers, and cryptocurrency miners in Bulgaria, understanding exact electricity costs is critical for profitability and budgeting. The formula is simple: kWh consumed = (Watts × Hours) ÷ 1000. Then multiply by your utility tariff rate to get the cost. A 500W system running 12 hours per day consumes 6.00 kWh daily, costing лв0.90 per day or лв27.00 per month at your current tariff.

For mining rigs, electricity is the #1 operational cost. A 6-GPU ethereum mining rig typically consumes 1,500–2,800W. At лв0.15/kWh, that's лв108.00/month just in electricity for a 2000W setup. This directly impacts mining profitability and the break-even period for hardware investment.
