Electrification Budget Allocation
With a fixed amount to spend this year, should it go toward one big-ticket conversion or two smaller ones? This tool compares putting your whole budget toward heating against splitting it across water heating and the range.
At your inputs, putting the budget toward water heating and the range costs $10,700 less over 10 years.
| Put the budget toward heating total cost over the horizon | $19,000 |
|---|---|
| Put the budget toward water heating + a range total cost over the horizon | $8,300 |
Breakeven: putting the budget toward water heating and the range has both the lower upfront cost and the lower annual cost, so there is no upfront tradeoff to offset.
- This uses planning estimates you entered, not a contractor quote or guaranteed savings.
- This compares two ways to spend a limited budget now; it does not evaluate spending on both at once.
What this also tells you: Even if your annual costs are 20% higher or lower than entered, the same option stays cheaper, with the advantage ranging from $9,080 to $12,320.
This is a planning estimate based on your entries. It does not size equipment, determine electrical or building-code compliance, verify incentive eligibility, or replace a contractor quote or professional energy audit.
Why this decision comes up
A fixed electrification budget forces a real tradeoff between depth (one big conversion) and breadth (two smaller ones), and the "obviously correct" answer is not always obvious once the actual annual savings are compared.
How this is calculated
Both allocation paths are compared as total cost over your ownership horizon: net cost plus annual cost carried forward. This treats the two smaller projects as one combined option against the one larger project.
A worked example
With the defaults (heating: $8,000 net cost, $1,100/year; water heating + range bundle: $5,400 net cost, $290/year; 10-year horizon), the bundle totals $8,300 against $19,000 for heating alone, a substantial advantage for the bundle at these defaults driven by its much lower combined annual cost.
Common mistakes
A common mistake is assuming a single big project is always more efficient to execute than two smaller ones. Total cost, not project count, is what actually determines the better economic choice.
Limitations
This does not model financing a follow-up project with savings from the first, or the urgency of any specific failing appliance, both of which are real factors in a phased electrification plan.
Common questions
How is this different from the sequencing tool?
Sequencing compares two single big projects head to head. This tool compares one big project against a bundle of two smaller ones, which is a different shape of tradeoff: fewer dollars of savings sooner, spread across two systems, versus more dollars of savings later from one.
Does bundling two smaller projects cost more in labor?
It can, if they require separate contractor visits, though some homeowners coordinate both in one visit to save on labor. Reflect your actual quoted costs, bundled or not, in what you enter.
What if my budget does not match either option exactly?
Adjust the entered costs to match your actual budget and quotes. The comparison logic works the same regardless of the specific dollar amounts.
Should I always prefer converting more appliances per dollar spent?
Not automatically. A bundle spreading savings across two systems can still lag a single high-savings project depending on each option's real annual cost, so compare the actual total-cost numbers rather than counting appliances converted.
Does the order I convert the bundled appliances in matter for this comparison?
Not for this tool's total-cost comparison. If you can only afford one of the two bundled projects immediately, the sequencing tool is the better fit for that specific ordering decision.
