Rent increase formula

New rent = Current rent × (1 + increase %)

Rent increase example

  • Monthly increase: $90
  • New monthly rent: $1,890
  • Extra cost per year: $1,080

What to check before you sign

  1. Local rules: California (AB 1482), Oregon and cities with rent stabilization cap yearly increases. Many other places have no cap but require advance notice.
  2. Market rents: Compare similar listings nearby. If the new rent is above market, negotiate or consider moving — but include moving costs.
  3. Lease length: A longer lease can lock in today’s rent.
  4. Your budget: Housing costs above about 30% of gross income strain most budgets. Test your plan with the budget calculator.

Rent or buy?

Frequently Asked Questions

How much can a landlord raise rent?

It depends on where you live. Most US states have no statewide cap, but California, Oregon and many cities with rent control limit annual increases, often tied to inflation.

How do I calculate a rent increase percentage?

Divide the difference between the new and old rent by the old rent and multiply by 100. Going from $1,800 to $1,890 is a 5% increase.

How much notice is required for a rent increase?

Notice rules vary by state and lease type, commonly 30 to 90 days for month-to-month tenancies. Fixed-term leases usually cannot be raised until renewal.
