Rent rarely stays the same. Use this calculator to project your future monthly rent based on an expected annual increase rate, see the total you'll pay over any time horizon, and compare the cumulative cost of renting to buying.
National average rent increases have historically ranged from 2–5% annually over long periods. During supply-constrained periods (like 2021–2022), increases reached 10–20% in some markets. Budget for 3–4% in a normal market, and consider your specific city when planning.
Higher rent growth makes buying more attractive over time because your mortgage payment is fixed while your rent keeps rising. If rent grows at 4% annually, a $2,000 rent today becomes roughly $2,960 in 10 years. That's why a longer time horizon and higher rent growth tend to favor buying.
It depends on local law. Some cities have rent control or rent stabilization laws that limit annual increases. Without rent control, landlords can typically raise rent at the end of each lease term by any amount, subject to proper notice (usually 30–60 days).
If your landlord proposes a large increase, you can negotiate by highlighting your track record as a tenant, offering a longer lease term in exchange for a lower increase, or providing market comparables showing lower rents for similar units. Signing a 2-year lease often gets you a smaller annual increase.
When rent grows faster than housing costs (including appreciation), buying becomes increasingly competitive over time. If your rent is rising 4–5% annually while your mortgage payment is fixed, the financial case for buying strengthens each year.

Rent increases compound, meaning each year's increase applies to the previous year's higher rent. A 4% annual increase on a $2,000 rent becomes $2,080 in year 1, $2,163 in year 2, and so on — not a flat $80 added each year. After 10 years at 4%, that $2,000 rent grows to about $2,960.
Rent stabilization (common in cities like New York and Los Angeles) limits how much a landlord can raise rent annually on qualifying units. The increase is typically tied to a percentage set by a local housing board. Rent control is stricter, sometimes capping rent at a fixed level. Neither applies to most rental units nationwide.
