Store Build-Out Cost Calculator
The build-out is usually the biggest one-time line in a store plan. Enter square footage and cost per square foot by concept type, add a contingency, and see a realistic renovation estimate — with typical $/sq ft ranges to sanity-check it.

What Drives Build-Out Cost
Square footage
The more space, the more of everything — but $/SF often drops on very large boxes.
Cost per square foot
The single biggest swing factor. Concept and scope (white-box vs full) set it.
Contingency
10–20% on top. Renovation runs over; budget for it explicitly.
Scope
Kitchens, plumbing, and custom millwork blow past a simple retail fit-out.
Estimate Your Build-Out
- Pick your concept preset. Restaurant, café, or retail sets a $/SF starting range.
- Enter square footage. The leased selling + back-of-house area.
- Set cost per square foot. Adjust from the preset toward your real bids.
- Add a contingency. 15% is a sane default.
- Read the total estimate. Base + contingency = realistic budget.
- Carry it into startup capital. Add to the Viability tool’s one-time costs.

Ranges vary widely by concept: retail white-box fit-out often $20–$75/SF, restaurants $50–$450/SF (kitchens, hoods, and plumbing drive the high end), and cafés somewhere between. Use the preset ranges in the calculator as a starting point, then get real bids.
Renovation almost always runs over. A 10–20% contingency is standard; we default to 15%. Skipping it is why so many store budgets blow up before opening day.
No — build-out is the space itself (construction, fixtures, flooring). Equipment, POS, and first inventory are separate one-time costs captured in the Startup Viability tool. Keep them distinct so you can track each.
White-box is a bare space brought to “vanilla” condition (floor, walls, basic HVAC/electrical) — cheaper. A full build-out adds concept-specific work (kitchen, restrooms, custom millwork) — far more expensive. The $/SF you enter should match the scope you are actually doing.
The build-out estimate is the largest one-time line in most store plans. Add it to equipment, inventory, licenses, and a working-capital reserve in the Startup Viability tool to size total capital.
