Why this page exists

Lease comparisons get easier when a TI allowance is turned into one total dollar figure instead of being left as a rate buried in the term sheet. This calculator helps visitors estimate total tenant improvement allowance from tenant square footage and the allowance per square foot so lease support can be compared more clearly.

Estimate total tenant improvement allowance from tenant square footage and allowance per square foot.

Result

$89,600

Estimated total tenant improvement allowance from tenant square footage multiplied by allowance per square foot.

Total tenant improvement allowance$89,600

Tenant square footage used3,200 sq ft

Allowance per square foot used$28.00

Allowance per 1,000 sq ft$28,000

3,200 square feet at $28.00 per square foot points to about $89,600 of total TI allowance.
This is useful as a quick lease-negotiation benchmark when comparing landlord build-out support across spaces.
Use the result as a simple estimate only, because reimbursement timing, caps, and approved uses can vary by lease.

This is a simple lease-planning estimate only. Actual TI structures can vary by lease language, reimbursement timing, landlord approvals, and negotiation terms.

How it works

What the calculator is doing

Enter tenant square footage and the TI allowance per square foot.

The calculator multiplies the tenant area by the allowance rate.

It shows the resulting total tenant improvement allowance together with the inputs used.

Understanding your result

This is a simple lease-planning estimate only. It is useful for comparing lease support levels, but actual TI structures can vary by reimbursement rules, landlord approvals, and negotiation terms.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Compare two lease offers

Turning the allowance rate into a total dollar figure makes it easier to compare build-out support across spaces.

Translate TI language into a project budget input

A simple total allowance can help show how much tenant improvement cost may still need to be funded separately.

When to use it

Good times to run this calculator

Use this when you want a quick TI-allowance estimate from square footage and a quoted allowance rate.

It is especially useful when comparing commercial leases that offer different levels of build-out support.

Assumptions and limitations

The estimate assumes the allowance applies evenly across the full tenant area entered.

It does not model reimbursement timing, landlord approval conditions, use restrictions, or how much of the build-out cost is still tenant-funded.

Common mistakes

Avoid the usual input mistakes

Looking only at base rent and ignoring TI support can make one lease look stronger or weaker than it really is.

Treating the total allowance like unrestricted cash can be misleading when the lease limits what the allowance may be used for.

Practical tips

Review the result beside CAM, effective-rent, and rent-per-square-foot tools so the TI allowance is weighed against the full occupancy-cost picture.

If the build-out is large, compare the TI estimate directly with the expected construction budget to see how much funding gap remains.

Worked example

Walk through a realistic scenario

A worked example shows how the estimate behaves when the inputs resemble a real planning decision.

Estimate total TI support for a leased space

A tenant wants to translate a quoted TI rate into a total dollar allowance before comparing it against another space.

1. Enter tenant square footage and the quoted TI allowance rate.

2. Multiply the area by the allowance rate.

3. Review the total dollar allowance as a lease-comparison input.

Takeaway: The total-dollar view is often the easiest way to compare tenant-improvement support across lease options.

FAQ

Common questions

How is tenant improvement allowance calculated here?

The calculator multiplies tenant square footage by the allowance per square foot to estimate the total TI allowance.

Why is a total TI allowance helpful?

It makes a lease-support rate easier to compare in real dollars when looking at build-out budgets or competing offers.

Will this match every lease exactly?

Not always. Some leases structure TI support with caps, reimbursement timing, approved-scope limits, or other negotiated details.

Related tools

Keep comparing

CAM, lease-escalation, rent-per-square-foot, and effective-rent tools help place TI allowance inside the full lease-cost workflow.

Budget and broker-commission tools add context when the allowance estimate is only one part of a broader occupancy-cost decision.
