Average rent increase per year
Use percentage change for one renewal and annualized growth for several years. Both start with the rent and the dates you are comparing.
$1,500 to $1,800 over three years
From October 2023 to October 2026, this hypothetical rent rises $300 per month, or 20% total. The equivalent compounded annual rate is about 6.27%.
The intermediate rents are calculated examples, not observed renewals.
Annualized change = [(ending rent ÷ starting rent)1/years − 1] × 100
Dividing 20% by three gives 6.67%, which spreads the total evenly without compounding. Use positive rents and the elapsed interval: October 2023 to October 2026 is three years.
A rise and fall do not cancel
A 10% increase takes $1,500 to $1,650. A 10% decrease then subtracts $165, leaving $1,485. The arithmetic average of +10% and −10% is zero, but the ending rent is 1% lower.
$1,500 × 1.10 × 0.90 = $1,485
The second change uses a larger base. The compounded annual rate for this two-year example is about −0.50%.
Compare like amounts
- Payment period
- Monthly rent against monthly rent. Handle partial months separately.
- Components
- Use the same fees and credits. Exclude deposits and one-time late fees from a base-rent trend.
- Dates
- Record both effective dates; six months and twelve months are different intervals.
For a lease with concessions, the net effective rent calculator shows the average across the whole term.
Turn the renewal into a budget amount
A rise from $1,800 to $1,890 is $90 a month and 5%. It adds $1,080 over twelve months, or $540 if only six months of your budget period are affected.
Use the rent increase calculator for your renewal. Before preparing a notice, verify the lawful amount and delivery requirements. The California guide covers that state’s rules.
Questions, answered
What is the average rent increase per year?
A market average needs a defined place, period and group of rentals. No verified national average is quoted here. For one lease, calculate each renewal’s change or the compound annual rate between two dates.
Can I divide a three-year increase by three?
That gives a simple annual share, not compound growth. A rise from $1,500 to $1,800 over three years is 20% total: 6.67% when divided by three, versus about 6.27% compounded annually.
Does an average increase tell me the legal maximum?
No. The lawful amount depends on the lease, property coverage and current state and local rules. An average does not establish that a proposed increase or notice is valid.
