Every project comes down to the same question: is it worth it? Whether you’re comparing new construction to your current lease or an aging facility, this calculator walks you through the real financial picture, including financing costs, efficiency gains, and tax benefits, and gives you a clear picture of when the investment pays for itself and what you save over time.
Return On Investment Calculator
See how building a new facility with Eagan Building Group compares to staying where you are. Plug in your own numbers to estimate payback period and long-term savings.
Your Project
Start with the basics of what you're planning to build.
Include construction, site work, design and engineering, permits, land if applicable, financing costs, owner equipment, and moving costs. Use your Space Planner estimate as a starting point.
Your Current Situation
What are you comparing this project against?
Current Annual Facility Cost
Break this out into whatever applies to your situation. Leave any field at 0 if it doesn't apply.

New Facility Annual Cost
A new building isn't free to run. Estimate what you'll pay each year so the comparison reflects real ongoing cost, not just what you'll save.
Total New Facility Annual Cost$0
Financing
20%
15 yrs
The number of years used to size your payment. Common commercial terms run 20-25 yrs.
15 yrs
How long you'll actually hold this loan before it's paid off or refinanced.

Efficiency & Growth Gains
Extra revenue the new space makes possible (added capacity, new lines, fewer lost orders). Enter revenue, not profit; contribution margin below converts it to a profit benefit.
25%
The share of that added revenue left after materials, labor, and other variable costs.
Tax Benefit
Estimated using standard straight-line depreciation, applied each year over your time horizon. Toggle below if you qualify for Qualified Production Property (QPP) or bonus depreciation instead — these are a distinct, largely one-time tax treatment, not the same thing as standard depreciation.
Building value only. Exclude land, which isn't depreciable.
21.0%
Combined federal and state rate. 21% is the federal corporate rate; pass-through entities are often higher.
Standard Depreciation (39-Yr)$0
Estimated annual tax savings at a full-year depreciation rate, applied each year of your time horizon (up to 39 years). The exact first-year amount depends on the month your building is placed in service.
QPP and bonus depreciation are accelerated, largely one-time deductions taken up front. This replaces the standard depreciation line above rather than adding to it. Not sure what applies to you? Estimate it with our QPP Tax Benefit Calculator, then enter the result here. Confirm with your CPA.

Disclaimer: This calculator produces an illustrative estimate based on the assumptions you enter. It is not financial, tax, or investment advice, and Eagan Building Group is a design-build general contractor, not a financial advisor or lender. Actual costs, financing terms, savings, and payback periods depend on factors not captured here, including final construction pricing, market conditions, loan qualification, energy and labor costs, and how your business changes over time. Tax savings entered above should be confirmed with a qualified CPA or tax professional; financing terms should be confirmed with your lender. Always verify these figures before making a financial decision.
