Questions people ask next

What is effective rent?

Effective rent is one lease number that converts a messy deal into a yearly figure after credits and extras.

How do you calculate it?

A simple method adds rent, subtracts credits, and spreads the result across the term so a tenant can compare. A tenant should keep this lease answer visible on the same page.

How is it different from face rent?

Face rent is the sticker on the lease. Effective rent should fold in free months and build-out money.

How is it different from NPV?

NPV is a lump sum in today's dollars. Effective rent is a level yearly lease number a tenant can quote.

Plain-language definition

Effective rent is an average. People use it to turn a messy lease into one rent figure.

It often includes free rent and sometimes TI money by spreading them over the years.

NPV means net present value. That tool keeps time. Effective rent often flattens time.

Both can help. They are not the same sentence.

Why it matters

Averages are easy in a meeting.

They can hide a painful year after a gift year.

A CFO may still want the average. Show the path too.

Brokers get in trouble when the average and the cash path disagree and no one said so.

How it works

The cash flow is the list of money in and out by year. Write that list first.

  • Add the rent you will pay. Subtract the credits you treat as rent relief.
  • Divide by the years or the occupied months you chose.
  • Say what you put in. Say what you left out.
  • Then, if timing matters, also show NPV.
Later cash boxes sit farther right and look smaller than year-one cash.
Later cash is smaller in today's dollars. This is a teaching picture, not a live model.

Formula in words. Effective rent ≈ (rent over the term − credits you spread) / years you chose to divide by.

How to read the sample

Sample NPV for the averaged lease is about $338,047. A second path lands near $327,414. That gap is a talking point, not a promise.

The average would smear this credit. If one path wins only because a credit sat in the wrong year, start over.

Assumptions

  • This hub treats effective rent as a teaching average, not a market index.
  • CAM may or may not be inside a given firm's 'effective rent.' Ask.

Edge cases

Some people exclude TI from effective rent. Say which camp you are in.

Monthly vs annual divisors change the headline.

Common mistakes

  • Calling an average 'NPV.'
  • Spreading a late credit as if it were cash today.
  • Leaving extras out of the average and the path.

Decision implications

Use effective rent to communicate. Use NPV to keep time.

If they disagree, show both.

Face rent is even thinner than effective rent.

Limits

  • There is no single official effective-rent law on this page.

When this should not drive the choice

  • When the question is 'when do I pay,' an average is the wrong lead.
