How this service works
Estimate a monthly electricity bill from kWh with block-tier rates, a fixed monthly charge and a tax or fee percentage.
Output
Returns a structured bill estimate including: total bill, energy charge subtotal, fixed charge, taxes, average price per kWh, unbilled kWh (if usage doesn't fill all tiers), a per-tier breakdown (kWh consumed, rate, and cost for each block), a human-readable summary, and optional disclaimer or degraded-mode flags.
Example use cases
Verify a utility bill before paying
“I just got my electric bill for 1,200 kWh. My plan charges $0.10 for the first 500 kWh, $0.14 for the next 500, and $0.20 for the rest, with a $9.50 monthly fee and 7% tax. Can you calculate what the bill should come out to and break it down by tier so I can check if it looks right?”
Compare flat rate vs tiered rate cost
“I use about 750 kWh per month. Right now I'm on a flat rate of $0.15 per kWh with a $10 service charge and 6% tax. What would my bill be, and can you show me the full breakdown?”
Budget for high-usage summer month
“This summer I expect to use around 1,800 kWh. My utility has three tiers: $0.11 for the first 600, $0.16 for the next 600, and $0.22 for anything above that. There's a $15 fixed charge and 9% taxes. What will my bill be and what's my average cost per kWh?”
Technical details
Endpoint
GEThttps://home-energy-calc.x402tookit.com/bill-estimate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, tier-aware electricity bill computation — especially when the user's utility plan uses block/stepped pricing. It handles multi-tier rate schedules, fixed service charges, and percentage taxes in a single call, returning a full breakdown. Prefer it over generic math tools when the output needs to be utility-bill-shaped (tier breakdown, average $/kWh, summary text).
Side effects
- Missing required 'kwh' or 'tiers' parameters returns an error
- Invalid tier string format (e.g., missing 'rest@rate' final block) causes a parse error
- kWh value out of range (negative or above 100000) may be rejected
- taxPercent outside 0–50 range may be rejected
- Malformed rate values (non-numeric) in tier string cause failures
