How do you calculate effective rent?

How do you calculate effective rent?

Add rent you pay, subtract credits, then spread the result across the term. A tighter method also prices waiting.

This page belongs to a validation / pilot concept. It is not generally available.

Questions this page also answers

What is the simple formula?

Total rent plus extras minus credits, divided by the term.

What is the tighter formula?

Discount the stream first. Then turn that sum into a level yearly amount.

Do you need a rate?

Only for the tighter method. The simple average does not price waiting.

Which should brokers show?

Show both when the rank might flip. Name the method.

Plain-language definition

Effective rent is one number that stands in for a messy deal.

Face rent is the sticker. Effective rent folds in free months and build-out money.

A simple method averages. A tighter method uses today's dollars first.

Say which method you used. The two are not the same.

This page sits under Effective rent.

Start from face rent so the room sees the sticker first.

The tighter method needs a discount rate.

Time credits before you divide.

The effective rent hub keeps the limits next to the formula.

Investopedia defines net present value as later cash brought back to today. That idea is the spine of this page. See Investopedia on NPV.

Why it matters

Clients ask for one foot number.

Two deals with the same sticker can have different effective rent.

The method choice can flip the rank.

How it works

Write the cash list first. Then decide what the page is measuring.

  • Write every payment and credit.
  • For the simple method, subtract credits from total rent and divide by term.
  • For the tighter method, discount the stream, then turn that sum into a level yearly number.
  • State the rate if you used the tighter method.
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. Simple effective rent = (total rent + extras − credits) / years. Tighter method = NPV turned into a level yearly amount.

Assumptions

  • The sample shows both methods on the same cash list.

Edge cases

A credit after year one changes the simple average less than it changes NPV.

Common mistakes

  • Calling a simple average an NPV result.
  • Forgetting TI.
  • Mixing gross and net.

Decision implications

If timing is the fight, use the tighter method. If the room wants a quick foot number, show both.

Compare this to related metrics

NPV keeps the lump sum. Effective rent turns it into a yearly foot number.

See effective rent vs NPV.

Limits

  • Neither method prices a renewal option well.

When this should not drive the choice

  • Do not use effective rent as the only slide when cash this year is the constraint.
