Live result1.8 yearsEstimated running cost $156.52/year; annual saving $1,643.48.

Formula used

Estimated heat pump running cost = current annual cost / 0.92 / COP x electricity rate. Annual saving = current annual cost - heat pump running cost. Payback = installed cost / annual saving.

This is the method behind the answer, so the result can be checked rather than simply trusted.

1.8 yearsEstimated running cost $156.52/year; annual saving $1,643.48.

Inputs

Current annual heating cost: 1,800 $
Heat pump COP: 3.5
Electricity rate: 0.28 $/kWh
Heat pump installed cost: 3,000 $

Method

Estimated heat pump running cost = current annual cost / 0.92 / COP x electricity rate. Annual saving = current annual cost - heat pump running cost. Payback = installed cost / annual saving.

With $1,800 current heating cost, COP 3.5 and $0.28/kWh, estimated heat pump running cost is about $156 and annual saving is about $1,644.

Assumptions

This calculator is for planning and education, not legal, tax, medical, immigration, engineering or financial advice.
Use current official rates, contracts, carrier terms, statutes or professional guidance before relying on the result.
The default values are examples. Replace them with the figures from the job, invoice, contract, bill, service or record being checked.

Methodology & Accuracy

How this calculator is checked

CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.

Formula used

Estimated heat pump running cost = current annual cost / 0.92 / COP x electricity rate. Annual saving = current annual cost - heat pump running cost. Payback = installed cost / annual saving.

Standard or basis

Basis: transparent planning arithmetic using the visible inputs and assumptions on this page.

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.

Master's Tip
