Build Cost (TCO) Estimator

The real monthly cost of a PC is more than the sticker price — spread the hardware and add the power bill.

Estimates only. These calculators use typical component specifications and rough rules of thumb. They are for planning and education, not purchase advice. Verify every number against your parts’ official datasheets before buying or building.

Spread your parts and peripherals over their lifespan and add electricity to see a true monthly cost of ownership (TCO) for your PC.

Result

About $39.33/month
Parts amortization$25/mo
Peripherals amortization$8.33/mo
Electricity$6/mo
Total monthly cost$39.33/mo
Based on ~450 kWh/year at $0.16/kWh. Longer lifespans and efficiency (lower load) cut the monthly number; overvolting or a high refresh rate at 4K raises it.
Total cost of ownership

TCO = (parts ÷ lifespan) + (peripherals ÷ peripheral lifespan) + (annual electricity ÷ 12). A higher-Wattage GPU or a 4K/ high-refresh monitor raises the electricity line; a longer planned lifespan lowers the monthly hardware cost. Electricity is estimated as average load × hours per year × your rate.
