1
Enter Current Rent
Your tenant's current monthly rent. The increase is calculated from this baseline.
2
Choose Increase Type
Percentage increases compound over time. Flat dollar increases are simpler but don't track inflation. Most landlords use % to preserve purchasing power.
3
Set Rent Control Cap
If your property is subject to rent control or rent stabilization, enter the maximum allowed percentage. The calculator flags if your increase exceeds the cap.
4
See the Annual Impact
Monthly rent increases look small. The table shows annual revenue gain -- a $70/mo increase = $840/year. At 10 units, that's $8,400/year to the bottom line.
5
Compound Over 5 Years
Consistent annual increases compound significantly. 5% annual increases on $1,400 reaches $1,786 in 5 years -- $386/mo more with no additional investment.
6
Give Proper Notice
Most states require 30-60 days written notice before a rent increase. Some require more notice for larger increases. Check your state's landlord-tenant law.

Regular rent increases are one of the most important -- and most overlooked -- aspects of rental property management. Even modest annual increases preserve purchasing power against inflation and gradually improve returns over time.


Landlords who haven't raised rents in 3-5 years are often significantly below market. A tenant paying $1,400 when market rent is $1,750 represents $350/mo or $4,200/yr in foregone income. Bringing rents to market (within applicable legal limits) dramatically improves property cash flow and value.


Check your local laws before raising rent: many cities have rent control or rent stabilization ordinances that cap increases, require specific notice periods, or restrict increases to once per year.
