Home renovation cost calculator

Enter your values

Estimate what a remodel may really cost after scope, finish, regional pricing, and contingency are all included, then compare that spend with a directional resale-recovery overlay.

Use 100 for a baseline market. Higher-cost regions may need a higher multiplier.

Example calculations

Tap an example to prefill the calculator with sample values.

Standard kitchen update

220 sq ft kitchen in a slightly above-baseline market

A common homeowner planning case where the goal is to compare likely spend with directional resale recovery rather than to price every cabinet line item.

Result: The all-in remodel lands in the low-$70k range with a sizable but incomplete resale-value recovery estimate.

Premium bathroom gut remodel

140 sq ft bath with higher finish and full-scope work

Useful when plumbing, tile, fixtures, and layout upgrades all push the project above a simple cosmetic refresh.

Result: Bathrooms can climb quickly in cost per square foot once premium fixtures and full-scope work are added.

Basement finish with tighter budget

900 sq ft basement in a baseline market

A practical estimate for owners comparing whether finishing existing square footage is cheaper than building an addition.

Result: Basement projects often deliver a lower cost per square foot than kitchens or additions, even after contingency is included.

How the renovation cost estimate works

The calculator starts with a project-type base cost per square foot, then adjusts that number for finish tier, scope depth, and regional pricing pressure before adding contingency.

It also applies a directional resale-recovery percentage by project type so you can compare the likely all-in remodel cost with a simple estimate of how much value might be recaptured at sale.

Renovation cost FAQs

Use these answers to interpret contingency, resale recovery, and remodel scope before treating the output as a real budget.

Why does the calculator include contingency?

Because remodels often uncover surprises once demolition begins. Hidden water damage, electrical updates, framing changes, and finish changes can all move the real number, so a contingency allowance is more realistic than pretending every remodel runs exactly to plan.

Which projects usually recover more value at resale?

It depends on the market, but kitchens, baths, and well-executed basement projects often recover a larger share of their cost than more customized or highly personalized work. The recovery number here is directional, not a guarantee.

What does a gut remodel mean in this model?

A gut remodel assumes a deeper scope than cosmetic work. It implies more demolition, broader trade involvement, and more replacement of hidden systems or finishes, which is why the multiplier is higher.

Does this replace an actual contractor quote?

No. This is a planning calculator only. Use it to frame budget and resale tradeoffs before collecting bids, not as a substitute for a contractor scope review or detailed estimate.
