Rent Increase Report

What would a rent increase really earn you?

A higher rent looks good on paper. But the management fee takes its share, and if your tenant chooses to move out instead, empty days and turnover costs can eat a year of the increase fast. Put in your numbers to see both sides.

The numbers below are examples to get you started. Change them to yours.

The rent

12% is the published rate for the Eclipse Landlord plan. Use 0 if you manage it yourself.

If the tenant chooses to leave instead

Some tenants move out rather than pay more. These two numbers show what that would cost you, so you can weigh it against the increase.

From the day they move out to the day a new tenant starts paying rent. Nationally, think about 36 to 85 days. Rentals listed on Apartment List took about 36 days from listing to signed lease in October 2026 (Apartment List, 2026). Homes sitting empty and for rent in 2025 had been empty a median of 2.8 months, about 85 days (U.S. Census Bureau, 2025). The first leaves out cleanup before listing. The second counts the homes still empty. Use your own home's history if you know it.
Cleaning, repairs and re-leasing, all together.

Before you raise the rent

Colorado has rules about when and how rent can go up. Here are three to know.

Once in 12 months

Colorado allows only one rent increase in any 12 months for a residential tenant.

Section 38-12-702, C.R.S.

No written lease? 60 days notice

If your tenant has no written lease, you must give at least 60 days written notice before the rent goes up.

Section 38-12-701, C.R.S.

Never to push a tenant out

A rent increase may not be used to push a tenant out of the home, or to get back at a tenant.

Sections 38-12-509 and 38-12-1307, C.R.S.

This calculator shows money only. It does not tell you whether an increase is allowed for your tenant, or what the market will bear. The move-out numbers are there for one case: your tenant chooses to leave rather than pay the new rent.

Not sure what the market will bear?

A rent set too high can cost more than it earns. A rent set too low leaves money on the table every month. Knowing what homes like yours rent for right now is the place to start.

How we figure it

  • Extra rent: the proposed rent minus the current rent, each month. Times 12 for a year.
  • After the fee: the extra rent times 1 minus the management fee percent.
  • Percent increase: the extra rent each month divided by the current rent.
  • A day's rent: the proposed rent times 12, divided by 365, after the management fee. A fee that is a percent of rent is not charged on rent you never collect.
  • One turnover: the empty days times a day's rent, plus the turnover cost. This is the "you could lose" number.
  • You could gain: a year of the increase, after the fee.
  • Years of the increase one move-out costs: one turnover divided by a year of the increase after the fee.
  • Empty days that wipe out a year: a year of the increase after the fee, minus the turnover cost, divided by a day's rent, rounded up to a whole day.
  • Turnover cost that wipes out a year: a year of the increase after the fee, minus the rent lost on your empty days.
  • Payback month: one turnover divided by the extra rent each month after the fee, rounded up to a whole month.

This is an estimate for comparing choices. It does not predict whether a tenant will stay or leave, or what any home will rent for.
