These calculators are undergoing a correctness audit against primary standards. Part of the logic still rests on engineering rules-of-thumb rather than rules traced to a dated edition of a code, and some published citations do not yet match the rule the code actually applies. Known defects are being fixed in sequence.

Treat every number here as a starting estimate to be checked, never as a design decision. Anything that will be built, energised, or submitted to an authority must be independently calculated and sealed by a licensed engineer who takes responsibility for the result.

Decision points: none remaining — the 30-day month and the five-year payback advice band were removed
Energy and payback results remain scenarios, but the engine no longer supplies any of the scenario: the month length, the tariff, the currency, the emission factor and the price difference are all caller-supplied or the result is withheld, and payback is reported as arithmetic with no advice band attached.

Energy Cost Calculator

Cost = kW × h × Rate

Use Your Actual Effective Rate

VerElect does not provide undated regional tariff presets. Enter the effective per-kWh rate from a current bill or tariff calculation, including the charges and adjustments relevant to your scenario.

MEASURED OR RATED INPUTS

Power Consumption *

W

Prefer measured average power for cycling or variable loads.

Hours per Day *

Days per Month *

Days the equipment is used per month; no month length is assumed. Yearly figures repeat this monthly pattern for 12 months — for every-day use across a 365-day year, enter 365 ÷ 12 ≈ 30.42.

Duty Cycle *

Fraction of the stated hours that the equipment is actually on; use 1 when power is already a measured average.

CURRENT BILLING INPUT

Currency *

Effective Electricity Rate *

…/kWh

Progressive blocks, fuel adjustments, taxes, demand charges, and fixed charges are not reconstructed by this simple per-kWh model. Changing the currency relabels the rate; it never converts or replaces it.

OPTIONAL EMISSIONS INPUT

Emission Factor (kg CO₂/kWh)

Optional. Without a current grid/source factor, emissions remain “not calculated.”
