Net cost after rebates

7000 $ (net cost)

Check your inputs

Tax credits typically reduce what you owe in taxes rather than being paid upfront like a rebate — confirm the specific mechanism and eligibility requirements for your program before counting on the savings.

Total rebates/credits
3000 $

With the figures above, the net cost after rebates comes to 7000 $ (net cost). Note that gross cost (before rebates) and flat rebate amount ($) sit at the edge of the range this calculator was checked against, so treat the output as indicative rather than settled. The method behind this is well established, though site conditions and material batches will move it somewhat. This is calculated for United States and cites IRC 2024. Building in another market?

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

Is a tax credit the same as a rebate?
Not quite — a rebate is often paid or credited relatively quickly after purchase, while a tax credit reduces what you owe when you file taxes, meaning you generally need enough tax liability to benefit from its full value.
Can I stack multiple incentives?
Often yes — many federal, state, and utility incentive programs can be combined, but each has its own rules and sometimes caps on stacking. Check each specific program's terms.
Do incentive rates change over time?
Yes, frequently — percentage rates for programs like federal energy tax credits have changed by legislation in the past and can change again, so always verify the current rate for your specific project timing rather than assuming a rate stays fixed.
