How to Interpret This New Hampshire Estimate
This section explains why the calculator may move up or down. For the legal framework, eligibility standards, and source citations, use the dedicated New Hampshire law guide.
Temporary alimony may be ordered while the case is pending and ordinarily ends when the divorce, legal separation, or annulment becomes effective. Final term or reimbursement alimony is governed by RSA 458:19-a and related provisions, which include formula, duration, deviation, and termination rules. In New Hampshire, alimony is designed to address financial disparity between spouses after divorce. A spouse may qualify if they have need, the other spouse has the ability to pay, and the requested award is reasonable under the statutory framework. New Hampshire courts consider the parties' respective incomes, expenses, assets, marriage length, and fairness. Reimbursement alimony may apply when one spouse made economic or noneconomic contributions that enhanced the other's earning capacity or property position.
New Hampshire has a statutory formula for term alimony, but the formula is limited by the recipient's reasonable need and the payer's ability to pay. Term alimony is generally calculated as the lesser of the recipient's reasonable need or 23% of the difference between the parties' gross incomes under current federal tax treatment. Courts may adjust the formula or duration if justice requires. The calculator uses gross income for this planning estimate. Planning approach: Statutory term alimony estimate: 23% of the difference between payer gross income and recipient gross income, limited by the recipient's reasonable need and the payer's ability to meet both parties' reasonable needs. New Hampshire uses a statutory term alimony formula based on gross income. Under current federal tax law, where alimony is generally not deductible to the payer and not taxable to the recipient, the formula is 23% of the income difference. If federal tax law changes so alimony is deductible to the payer and taxable to the recipient, the statutory formula changes to 30% of the income difference. The formula is not an automatic entitlement; the court must find need, inability to self-support at a reasonable level, and ability of the other spouse to pay. The court may adjust the amount or duration if justice requires.
Because New Hampshire uses equitable distribution rules, property division under N.H. Rev. Stat. Ann. §§ 458:19, 458:19-a, 458:19-aa, and 458:19-b may reduce ongoing alimony need. New Hampshire uses a statutory term-alimony formula rather than pure discretion.
Marriage duration shapes both amount and length of support in New Hampshire. For mid-length marriages, term alimony may provide support for a defined period tied to the statutory duration limit. Courts may consider deviation if the formula or duration cap would be unjust. Duration guidelines: The maximum duration of New Hampshire term alimony is generally 50% of the length of the marriage, unless the parties agree otherwise or the court finds that justice requires an adjustment. Term alimony ends on the recipient's remarriage unless the parties' agreement provides otherwise. Reimbursement alimony is separate, compensates contributions to the payer's financial resources, and is generally capped at 5 years from the final decree unless the parties agree otherwise.
RSA 458:19 defines alimony terms used in New Hampshire's alimony framework. RSA 458:19-a governs term and reimbursement alimony, including duration limits and deviation authority.

Estimated Support Duration Range
The maximum duration of New Hampshire term alimony is generally 50% of the length of the marriage, unless the parties agree otherwise or the court finds that justice requires an adjustment. Term alimony ends on the recipient's remarriage unless the parties' agreement provides otherwise. Reimbursement alimony is separate, compensates contributions to the payer's financial resources, and is generally capped at 5 years from the final decree unless the parties agree otherwise.
How long alimony lasts in New Hampshire: The maximum duration of New Hampshire term alimony is generally 50% of the length of the marriage, unless the parties agree otherwise or the court finds that justice requires an adjustment. Term alimony ends on the recipient's remarriage unless the parties' agreement provides otherwise. Reimbursement alimony is separate, compensates contributions to the payer's financial resources, and is generally capped at 5 years from the final decree unless the parties agree otherwise.
Short-term marriages: Short marriages often result in no alimony or brief term alimony if need and ability to pay are shown. The 50%-of-marriage-length cap usually keeps support duration short. Typical range: 0-5 years.
Mid-length marriages: For mid-length marriages, term alimony may provide support for a defined period tied to the statutory duration limit. Courts may consider deviation if the formula or duration cap would be unjust. Typical range: 5-20 years.
Long-term marriages: Long-term marriages may support longer term alimony and greater likelihood of deviation issues. Courts still apply statutory duration limits unless an agreement or justice-based adjustment supports a different result. Typical range: 20 years to potentially adjusted duration.
Termination in New Hampshire: Term alimony generally ends on the date set in the order and terminates upon remarriage of the recipient unless the parties' agreement provides otherwise. Statutory termination rules may also apply for cohabitation, death, or other events depending on the award type.
Inputs That Can Change the Estimate
New Hampshire judges apply N.H. Rev. Stat. Ann. §§ 458:19, 458:19-a, 458:19-aa, and 458:19-b and weigh multiple factors when setting alimony. New Hampshire uses the term alimony and provides a structured statutory framework for temporary, term, and reimbursement awards. The state uses a formula-based approach for many term alimony calculations, but courts may deviate when justice requires. Duration is also limited by statute, with term alimony generally capped at 50% of the length of the marriage.
Income and earning capacity: New Hampshire courts evaluate the income and reasonable expenses of each spouse. The calculator reflects income disparity through this planning approach: Statutory term alimony estimate: 23% of the difference between payer gross income and recipient gross income, limited by the recipient's reasonable need and the payer's ability to meet both parties' reasonable needs.
Marriage duration: For mid-length marriages, term alimony may provide support for a defined period tied to the statutory duration limit. Courts may consider deviation if the formula or duration cap would be unjust.
Standard of living and health: New Hampshire courts consider the length of the marriage and the statutory duration cap. New Hampshire courts review assets, liabilities, and property division after the New Hampshire divorce.
Property and regional factors: New Hampshire uses a statutory term-alimony formula rather than pure discretion. Term alimony duration is generally capped at 50% of the marriage length. Temporary alimony is not automatically counted toward formula or duration limits unless unusually long. Reimbursement alimony is a separate statutory category.
