16th of 259 in New Hampshire, 3rd on area income

- Difference (%)

- Rank in state
- Tied at 16 of 259
The two-bedroom Fair Market Rent applicable to Londonderry town is above the state median for NH. It is tied at rank 16 of 259 county-subdivision records by 2BR FMR, sharing that rank with 5 other county-subdivision records at the same rent.
The other 5 records in this HUD area use the same 2BR FMR and therefore share this rank.
Rank 1 is the highest 2BR FMR in the state, and county-subdivision records with an identical rent share a rank. “Approximately at the state median” means within 2% of it. The median is taken across the 259 county-subdivision records published for NH — it is a median across entity records, not weighted by households or population, and not a median over unique HUD areas, so a HUD area covering several entities counts once per entity record. County subdivisions are only ever compared with other county subdivisions, never with counties.

This is a ratio between two HUD benchmarks for the Western Rockingham County, NH HUD Metro FMR Area area: the annualized two-bedroom Fair Market Rent divided by HUD Median Family Income. It is not a measured rent burden, not the share of income any particular family spends on housing, and not an affordability or eligibility determination.

One county, four rent areas, four different figures
The 37 Rockingham County records in this dataset publish $2,194 for 16 of them, $2,270 for 13, $2,220 for the 6 towns of this area and $2,941 for the remaining 2. The area incomes behind those rents are $140,900, $137,300, $154,100 and $164,600. Nothing about the county boundary predicts which of the four a given town falls into.
Two of the four are named after Massachusetts metropolitan areas rather than New Hampshire ones. Derry town, immediately south of here, is priced inside the Lawrence, MA-NH area at $2,270; Seabrook town on the coast is inside Boston-Cambridge-Quincy, MA-NH at $2,941, the highest figure published for any New Hampshire record. The largest group belongs to Portsmouth-Rochester, which covers Portsmouth city and 15 other Rockingham towns at $2,194 — and it does not stop at the county line: 13 more of its members sit in Strafford County, for 29 in all.
New Hampshire has 14 HUD areas in total for its 259 town records. One county accounts for 4 of them, which is why the useful question on a New Hampshire page is which area a town is in rather than which county.

Purchasing power decision engine
Decision snapshot (server-rendered)
Baseline: HUD Median Family Income adjusted from 2025-07 to 2026-07 using embedded CPI-U monthly series.
- Adjusted income is near the local median and/or purchasing power decreased materially.
- This suggests moderate affordability risk under CPI-U adjustment assumptions.
Purchasing power decision tool (CPI-U monthly)
This module converts an annual income from 2025-07 into its 2026-07 equivalent using the CPI-U series, then compares it to the HUD Median Family Income for Londonderry town, NH.
The baseline is HUD's Median Family Income for the HUD area, not a Census median household income. The CPI-U series is the official BLS CUUR0000SA0 index, unadjusted; months BLS did not publish are left out rather than interpolated.
HUD Median Family Income (annual): $154,100
Decision output
- Adjusted income is near the local median and/or purchasing power decreased materially.
- This suggests moderate affordability risk under CPI-U adjustment assumptions.
Methodology & assumptions (v1.0)
Adjusted income is computed as Income × CPI(to) / CPI(from) using CPI-U monthly index values embedded in this page.
- CPI-U is an aggregate price index for urban consumers; individual consumption patterns may differ.
- No interpolation is applied; both selected months must exist in the dataset.
- HUD Median Family Income is treated as the annual reference benchmark for the applicable HUD area, compared to adjusted annual income.
- This module performs a historical transformation, not a forecast.

Sources & methodology
HUD income limits and Fair Market Rents are taken from the fiscal-year tables HUD publishes per HUD-defined area — which can include more than one county subdivision — and joined to this county-subdivision record. State comparisons are computed across the 2BR Fair Market Rents of the county-subdivision records in the same state; county subdivisions are never ranked against counties. The median uses the middle value and is not weighted by households or population, rank 1 is the highest rent in the state, and county-subdivision records with identical rents share a rank.
The income figure used throughout this page is HUD's Median Family Income for the HUD area above. It is not a Census median household income and the two are not interchangeable.
The purchasing power module applies a historical CPI ratio: Adjusted = Nominal × CPI(to) / CPI(from). No interpolation is applied and missing months are not imputed; CPI-U is a historical index, not a forecast. The “STABLE” target adds a fixed +10% buffer over the local HUD Median Family Income — that buffer is a GovCalculator heuristic, not a HUD, BLS or IRS determination.
The CPI-U series is the official BLS CUUR0000SA0 index, not seasonally adjusted, taken from the published BLS series: 36 published monthly observations. Months BLS did not publish are not interpolated. IRS Publication 15-T is cited as an official reference only — no federal withholding is calculated anywhere on this site.
Verify eligibility requirements with local program administrators: household size, deductions, and program-specific definitions can materially change outcomes.
FAQ
Which fiscal years are shown on this page?
Income limits are FY2026 and Fair Market Rents are FY2026.
What is the Fair Market Rent (2BR) here?
The two-bedroom Fair Market Rent is $2,220 per month. Fair Market Rents for studio through four-bedroom units are listed in the bedroom table above.
Do the income limits on this page decide whether I qualify?
No. They are the thresholds HUD publishes for this area. Programs apply their own rules, and adjusted-income definitions — deductions, allowances, and which household members count — can change the outcome for a given household.
What does the FMR-to-median-family-income share mean?
It is the annualized two-bedroom Fair Market Rent divided by HUD Median Family Income for the same area, here 17.3%. Both inputs are HUD area benchmarks, so it is not a measured rent burden and not an affordability determination.
How does Londonderry town rank within NH?
Its applicable two-bedroom Fair Market Rent is tied at rank 16 of 259 county-subdivision records in NH, shared with 5 other county-subdivision records at the same rent. Rank 1 is the highest rent in the state, county-subdivision records with identical rents share a rank, and county subdivisions are never ranked against counties. That places it above the state median.
Why is Londonderry town a HUD county subdivision rather than a county?
HUD publishes FY2026 income limits and Fair Market Rents for the six New England states at town/city (county subdivision) level, not county level — there is no county-equivalent HUD record for NH. Londonderry town sits in Rockingham County, a county.
Is the CPI-based purchasing power module a forecast?
No. It is a historical adjustment using CPI-U monthly index values: Adjusted = Income × CPI(to) / CPI(from). It does not predict future inflation.
Does this page calculate federal income tax withholding?
No. GovCalculator does not compute federal withholding anywhere. IRS Publication 15-T is cited as an official reference only; its withholding methods and tables are not ingested or modelled here.
Does every town in Rockingham County have these figures?
No. The county's 37 town records are divided among 4 HUD areas, and each publishes its own two-bedroom Fair Market Rent: $2,194 for 16 towns, $2,270 for 13, $2,220 for the 6 in this area and $2,941 for 2. The area median family incomes differ too — $140,900, $137,300, $154,100 and $164,600 — so the income limits differ with them. County lines and HUD rent-area lines are not the same lines.
What is the "Western Rockingham County" area?
It is the HUD Fair Market Rent area these figures are published for: Auburn, Candia, Deerfield, Londonderry, Northwood and Nottingham — 6 towns, all in Rockingham County. New Hampshire has 14 HUD areas altogether across 259 town records, and this county alone contains 4 of them. GovCalculator reports the areas as HUD defines them and does not reconstruct why a given boundary was drawn.
