Rent Increase Calculator
Calculate projected monthly rent after annual percentage increases over 1 to 10 years.
Returns year-by-year schedule and cumulative rent paid.
Rent increase calculations help both landlords and tenants understand the financial impact of a percentage or fixed-dollar rent adjustment.
Core formulas: New Rent = Current Rent × (1 + Increase Rate) Dollar Increase = Current Rent × Increase Rate Annual Impact = Dollar Increase × 12 Cumulative Rent (n years) = Current Rent × (1 + r)^n
Where:
- Current Rent = the current monthly rent amount
- Increase Rate = the annual percentage increase as a decimal (e.g., 5% = 0.05)
- n = number of years of compounding
Typical rent increase benchmarks (US, 2025):
| Context | Typical Annual Increase |
|---|---|
| CPI-linked (inflation-based) | 2.5–4% |
| Market-rate adjustment | 3–8% |
| High-demand urban area | 5–15% |
| Rent-controlled jurisdiction | 1–3% (capped by law) |
| New lease (tenant turnover) | Up to 20–30% in hot markets |
State rent control laws (selected):
- California: Statewide cap of CPI + 5%, maximum 10%
- Oregon: CPI + 3%, maximum 10%
- New York City: Rent Stabilization Board sets annual allowable increases
- Most states: No rent control — market rate applies
Worked example: Current rent: $1,850/month. Landlord proposes a 6% increase. Dollar increase = $1,850 × 0.06 = $111/month New rent = $1,850 + $111 = $1,961/month Annual impact = $111 × 12 = $1,332/year more
After 5 years at 6% annually: Rent = $1,850 × (1.06)⁵ = $1,850 × 1.338 = $2,475/month
Tenant strategy: Research comparable rents (Zillow, Apartments.com) before negotiating. Landlords typically prefer a reliable tenant over vacancy — a counter-offer of 3–4% is often accepted.
