A rent increase in dollars is your rent times the percentage. On a $2,000 rent, a 7% increase is $140 a month, which adds up to $1,680 over a year.
Then come the harder questions: how the rise compares with rents nationally, what it grows to, and whether it's affordable.
What each percentage adds to a $2,000 rent
Here's the same $2,000 rent at five different increases:
| Increase | Extra per month | New rent |
|---|---|---|
| 2.7% | $54 | $2,054 |
| 3% | $60 | $2,060 |
| 5% | $100 | $2,100 |
| 7% | $140 | $2,140 |
| 10% | $200 | $2,200 |
The first row, 2.7%, matches the national rent index over the year to August 2026, covered below. Talking a 7% notice down to 5% saves $40 a month, or $480 a year.
Why five 5% raises come to more than 25%
Each increase applies to the rent you already pay, earlier increases included. That's compounding, and it adds up faster than the percentages suggest:
| Yearly increase | Years | Rent at the end | Total rise |
|---|---|---|---|
| 3% | 5 yr | $2,319 | $319 |
| 5% | 5 yr | $2,553 | $553 |
| 7% | 5 yr | $2,805 | $805 |
| 3% | 10 yr | $2,688 | $688 |
| 5% | 10 yr | $3,258 | $1,258 |
| 7% | 10 yr | $3,934 | $1,934 |
Five 5% raises lift $2,000 by $553. That's 27.6%, not 25%. Keep 5% going for ten years and the rent rises 62.9%, to $3,258. At 7% a year, it nearly doubles in ten years. The inflation calculator runs the same compounding for any rate and number of years.
Is your increase higher than inflation?
The Bureau of Labor Statistics (BLS) tracks rents in the consumer price index (CPI). In the 12 months to August 2026, its index for rent of primary residence rose 2.7%. Prices overall rose 3.4%, so any rent rise below that fell behind prices in general.
So a 7% increase is more than twice the national rent trend. Your area can differ, though. The BLS says local-area indexes are more volatile than the national or regional indexes.
If your lease ties increases to the CPI, check which index it names. For escalator clauses, the BLS urges users to consider adopting the national or regional CPIs.
Reading a notice that gives dollars, not a percentage
If your notice states only the new rent, divide the rise by the old rent. Going from $1,850 to $1,995 is (1,995 − 1,850) ÷ 1,850 = 7.84%. The year-over-year growth calculator does that division for any two figures.
Dividing by the new rent instead gives the calculator's "as a share of the total" figure. On $2,000 raised 5%, that's $100 ÷ $2,100 = 4.76%. It shows how much of the new rent is the increase, so don't quote it as the raise.
Can you still afford the new rent?
HUD defines cost-burdened families as those "who pay more than 30 percent of their income for housing." That 30% line traces back to a 1969 amendment that capped public housing rent at 25% of income. Congress raised the cap to 30% in 1981.
To stay at that line, each extra dollar of rent needs about $3.33 of extra income. So the $140 rise from a 7% increase needs about $467 more a month, or $5,600 a year. The rent calculator finds the rent that fits a share of income you choose.
Your pay matters as much as the rent. Say rent takes 30% of your income, then rises 7% while your pay rises 3%. The share climbs to 30% × 1.07 ÷ 1.03 = 31.2%. The pay raise calculator shows your new salary for any raise.
Before you reply to the notice
- Your lease: the calculator can't read it. If the lease sets the rent for its term, or its own increase formula, compare the notice against it.
- Local rules: if your state or city caps increases or sets notice periods, check the result against them. The calculator doesn't apply any cap.
- Other charges: if parking, pet or utility charges rise too, add them to the monthly figure before you compare.
