BottleneckCalculator.in helps PC builders make clearer decisions about component pairing, power requirements and ongoing electricity costs.
Our purpose
Choosing computer components can be confusing. We provide simple, practical tools to help gamers, students and PC enthusiasts evaluate their options, especially when comparing affordable builds in India.
What you can calculate
- CPU and GPU pairing: a broad, scenario-based indication of which component may become performance-limiting.
- Power supply planning: an estimated starting PSU wattage from user-entered power values and headroom.
- Electricity cost: a monthly estimate based on wall power, usage hours and your actual tariff.
Transparency and limits
CPU/GPU results are educational estimates based on simplified illustrative hardware tiers. They are not laboratory benchmarks or guaranteed FPS predictions. Actual outcomes depend on each game, settings, memory, drivers and temperatures.
We prefer explaining uncertainty rather than displaying an unsupported exact “bottleneck percentage.” We encourage you to check credible third-party benchmarks and manufacturer documentation before purchasing.
Independence
Tools can be used without creating an account. If advertising or affiliate relationships are introduced, we intend to disclose them clearly and retain editorial independence.
