Weighted Average Lease Term Calculator

WALT (Weighted Average Lease Term) is the SF-weighted average of remaining lease years across the rent roll. It signals how durable cash flow is — the higher the WALT, the longer current rents are locked in. Lenders, buyers, and rating agencies use WALT to size loan terms and price acquisition cap rates. This calculator handles up to 4 tenants with custom remaining-term inputs.

How the math works

Weighted Average Lease Term (WALT) = sum of (tenant SF × remaining years) ÷ total SF. WALT under 3 years means most leases roll soon and rollover risk dominates. WALT over 7 years means stable cash flow with minimal near-term re-leasing burden.

Lenders use WALT for loan term sizing — typically refinance window must close before WALT runs out, so a 5-year WALT can support a 5-year fixed-rate loan.

How this calculator works

What this page estimates

This Weighted Average Lease Term Calculator is built to give a quick, browser-based estimate for weighted average lease term. WALT (Weighted Average Lease Term) is the SF-weighted average of remaining lease years across the rent roll. It signals how durable cash flow is — the higher the WALT, the longer current rents are locked in. Lenders, buyers, and rating agencies use WALT to size loan terms and price acquisition cap rates. This calculator handles up to 4 tenants with custom remaining-term inputs. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the weighted average lease term result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this weighted average lease term estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

What's a healthy WALT?

Industrial 5-8 years; office 4-7; retail 5-10; STNL 10-20. Under 3 means significant near-term rollover. Over 10 supports long-fixed-rate financing.

Should WALT use NOI or SF weights?

Both are common — SF for property management views, NOI for credit risk. NOI weighting penalizes short-WALT high-rent leases.

Does WALT include extension options?

Conservative WALT excludes options (since they're tenant decisions). Aggressive WALT includes options likely to be exercised — rare in institutional underwriting.
