How This Calculator Works
This tool multiplies your electricity usage in kWh by the average per-unit rate for Nakhon Ratchasima, adds any fixed monthly service charge, then applies the local tax rate to estimate your total bill. Domestic (household) and commercial (business) connections are calculated separately because Provincial Electricity Authority (PEA) bills them on different rate schedules. Enter your usage above to see the energy charge, fixed charge and tax broken out individually, updated instantly as you type.
Tips to Lower Your Electricity Bill
- ✓ Switch to LED bulbs — they use up to 80% less energy than incandescent bulbs for the same brightness.
- ✓ Set air conditioners to 24–26°C (75–78°F) rather than running them colder than needed; each extra degree saves roughly 3–5% on cooling costs.
- ✓ Unplug chargers and electronics left on standby — phantom load can quietly add 5–10% to a monthly bill.
- ✓ Run washing machines and dishwashers with full loads, and on off-peak hours if your tariff has time-of-use pricing.
- ✓ Clean or replace air conditioner filters every 1–3 months so the compressor doesn't have to overwork.
- ✓ Re-run this calculator month to month with your actual meter reading to catch unusual usage spikes early.

How often are electricity bills issued, and how do I match this calculator to my billing cycle? +
Billing frequency depends on the utility — most bill monthly, though some bill every two months or quarterly. Use the billing period selector above to match your own utility's cycle: if your bill covers two months of usage, choose the bi-monthly option so the fixed charges and tax are calculated over the correct period instead of a monthly period.
