How to calculate Closing Cost in New Hampshire

8 min read

Published April 15, 2026 • By DocketMath Team

Quick takeaways

Run this scenario in DocketMath using the Closing Cost calculator.

  • In New Hampshire, “closing costs” for a real estate transaction are typically computed from an itemized list (lender fees, third-party charges, taxes/recording fees, and prepaids), not from a single statutory formula.
  • DocketMath’s Closing Cost calculator helps you total those line items consistently for US-NH by keeping the math traceable and auditable, using jurisdiction-aware configuration where applicable.
  • New Hampshire’s general civil statute of limitations is 3 years under RSA 508:4. No claim-type-specific sub-rule was found in the provided jurisdiction data, so treat this as the default for general timing/recordkeeping discussions—but it does not change the arithmetic of adding closing-cost line items.
  • If your result looks “too high,” the most common causes are:
    • a missing category (especially prepaids like prorated interest/escrow deposits), or
    • the same charge entered twice (e.g., once as a fee and again as a prepaid).

Warning: This guide explains how to calculate and organize closing costs. It doesn’t determine what you can legally recover or dispute in a specific case. For legal advice, speak with a licensed professional.

Inputs you need

Before you run DocketMath’s Closing Cost calculator, gather the same documents you’d typically use to produce an accurate Closing Disclosure (or settlement statement) breakdown.

Use this intake checklist as your baseline for Closing Cost work in New Hampshire.

  • jurisdiction selection
  • key dates and triggering events
  • amounts or rates
  • any caps or overrides

If any of these inputs are uncertain, document the assumption before you run the tool.

1) Transaction basics (for context)

  • County / venue (optional for the math, helpful for labeling fee descriptions)
  • Purchase price (useful if your statement includes percent-based items tied to price)
  • Closing date (useful for aligning prorations and prepaids with the settlement period)

2) Fee categories (itemized amounts)

Use your Closing Disclosure / HUD-1 to list each charge. In DocketMath, you’ll map them into categories like:

  • Lender/financing charges

    • Origination / underwriting fees
    • Discount points (if stated as a percentage)
    • Appraisal and credit report fees
    • Mortgage insurance premium (if financed or collected at closing)
  • Third-party service fees

    • Title search / title insurance premium(s)
    • Attorney fee(s) (if applicable)
    • Survey fees
    • Recording services (clerks often provide itemized estimates)
  • Government/tax/recording items

    • Recording fees (county clerk)
    • Transfer-related state/county charges as shown on your statement
  • Prepaids

    • Escrow deposits (taxes, insurance)
    • Homeowner’s insurance premium paid upfront
    • Interest paid in advance (often a prorated figure from settlement to month end)

3) Optional but recommended calculation inputs

  • Loan amount (required if any lender fees are listed as “% of loan”)
  • Rate / interest terms (only needed if you’re rebuilding prorations rather than using statement totals)
  • “Paid by borrower” vs “paid by seller” flags
    • If your goal is a borrower-only total, you’ll want to keep this distinction clear when entering line items.

4) Dispute-timing input (recordkeeping context)

Timing doesn’t change the arithmetic of your total, but it does affect how long you should keep documentation:

Important: The provided jurisdiction data did not identify a claim-type-specific sub-rule, so RSA 508:4 should be treated as the default for the general timing discussion in this guide.

How the calculation works

DocketMath’s Closing Cost calculator (jurisdiction: US-NH) is designed to keep totals traceable: each line item you enter becomes part of the closing cost sum, and category subtotals roll up into the final number.

Because closing costs are generally itemized (not derived from one statutory formula), the calculation core is:

  1. Convert each fee line into a numeric amount (or compute it when it’s percent-based).
  2. Assign it to the correct category (lender/financing, third-party, government/recording, or prepaids).
  3. Sum the amounts you want included (for example, borrower-paid only).
  4. Keep prepaids separate so you can report either:
    • fees only, or
    • fees + prepaids (often aligned with “cash to close,” depending on how your settlement statement is formatted).

Category math (use this structure as your mental model)

CategoryWhat you includeExample line item
Lender / financingFees charged by lender or tied to financingOrigination, underwriting, credit report
Third-partyServices purchased for the transactionTitle work, survey
Government / recordingClerk and recording fees shown on settlement docsRecording fees
PrepaidsAmounts collected upfront at/for closingEscrows, homeowners insurance, prepaid interest

Percent-based fees: how they change your output

If your statement lists something like: “Origination fee: 1.0% of loan amount”, then:

  • Fee amount = Loan amount × 1.0%

In DocketMath, this means:

  • If you increase loan amount by $10,000, a 1.0% fee increases by $100 (before any separate flat fees).
  • Using the correct base (typically loan amount, not purchase price) is key for matching the statement.

Prepaids: why they often surprise people

Prepaids frequently cause confusion because they’re collected at closing and can be substantial even if they aren’t “fees” in the everyday sense.

DocketMath keeps prepaids distinct so you can:

  • compare Fees total versus Fees + prepaids total, and
  • reduce the risk of double-counting (for example, entering both an escrow total and the escrow components).

Common double-counting example: You enter an escrow deposit as a prepaid, and then also enter a “tax/insurance escrow” component under fees. The total inflates even though each line item came from the same statement.

Jurisdiction-aware rules (New Hampshire)

For the jurisdiction aspect in the provided data, the only cited rule is a general civil statute of limitations:

  • RSA 508:4: 3 years (general/default)
  • No claim-type-specific sub-rule was found in the provided jurisdiction data

How this affects your closing cost “calculation”: it doesn’t change how you total line items. Instead, it supports the recordkeeping/timing part of your workflow (keeping the documents you used to compute the total).

Common pitfalls

Use this checklist while entering charges into DocketMath’s Closing Cost calculator for US-NH:

  • Missing a category (especially prepaids like escrow deposits or prepaid interest)
  • Duplicate entry (the same charge entered in both fees and prepaids)
  • Mixing borrower-paid and seller-paid amounts without filtering
  • Rounding too early (round per-line can shift totals compared to statement rounding)
  • Using inconsistent versions (estimate vs final numbers across different categories)
  • Percent fee miscalculation (wrong base—commonly using purchase price instead of loan amount)

Quick sanity checks you can run

  • Does your total closely match the “Borrower paid at closing” section of the settlement statement (accounting for expected rounding)?
  • If the statement lists prepaids, are they included exactly once in your input?
  • Do any descriptions appear to be entered twice under different headings?

Warning: Some statements include adjustments (like prorated items). If you rebuild prorations manually, you must use the same day-count method and dates as the statement; otherwise, you may not match the official disclosure totals.

Sources and references

Start with the primary authority for New Hampshire and confirm the effective date before relying on any output. If the rule has been amended, update the inputs and rerun the calculation.

Next steps

  1. Collect your itemized settlement data (Closing Disclosure or HUD-1 equivalent) and separate into:
    • lender/financing fees,
    • third-party fees,
    • government/recording items,
    • prepaids.
  2. Enter the line items into DocketMath using the correct category mapping for US-NH.
  3. Run two totals:
    • Fees total (exclude prepaids), and
    • Fees + prepaids total (or “cash to close,” depending on what you’re trying to mirror).
  4. Audit the biggest drivers:
    • identify your top 5 charges,
    • confirm each appears once and is in the right category.
  5. Keep records for at least 3 years as general civil timing guidance under RSA 508:4 (based on the provided jurisdiction data’s default rule).
