New Hampshire Alimony Calculator

New Hampshire relies on subjective judicial discretion.

New Hampshire courts weigh RSA 458:19-a factors — each spouse’s financial resources, needs, earning capacity, and the standard of living during the marriage — to set a support order. New Hampshire regularly awards “contractual alimony” set by agreement, but litigated awards follow the factors, not a formula.

Because New Hampshire leaves alimony to the court, there is no single correct number. Our result is a range built on the AAML guideline (30% of the payer’s gross income minus 20% of the recipient’s, adjusted for children) — the band from the least-supportive to the most-supportive outcome judges commonly reach after weighing the standard of living, age, health, and earning capacity of both spouses.

Duration: New Hampshire has no duration table; terms are set to meet the statutory factors and are frequently structured as fixed-term contractual alimony.

Lump-Sum Alimony Buyouts & Post-Support Cash Flow in New Hampshire

Most New Hampshire support awards are agreed as a set of monthly payments — but the same money can be settled in one payment up front. That trade is called an alimony buyout: instead of writing a check every month for years, the payer hands over a single lump sum today, often by letting the recipient keep more of the house or more of a retirement account, so both spouses can move on cleanly. New Hampshire’s own amount and duration rules (RSA 458:19-a) set how much is paid each month and for how long, and that monthly stream is the thing being bought out.

Why is one payment today worth less than adding up every future check? Because money in hand now can sit in a safe account and earn interest over the same years those checks would have arrived. This alimony buyout calculator shows the same payment stream at 3.5%, 4.5% and 6.0% — the higher the rate, the smaller today’s lump sum, and the wider the gap between “paid monthly” and “paid up front”. Taking the deal up front means accepting a lump sum spousal support payment today instead of years of monthly checks.

In the 12-year, $120,000 payer / $40,000 recipient scenario used above, the monthly checks add up to $135,314 over 58 months — but settled as one single payment today they are worth $121,406 at 4.5%, $124,321 at 3.5% or $117,208 at 6.0%. That difference is what a settlement is really negotiating: the payer pays less in total, and the recipient gets the money sooner.

After the estimated $2,333-per-month transfer, the payer keeps about $5,167 per month (52% of the combined post-transfer total) and the recipient has about $4,833 (48%). The question after support is the simple one: what does each household actually have left to live on? The take-home split shows both sides after estimated taxes and after the payment, and since 2019 alimony is neither taxable for the receiver nor deductible for the payer, every dollar moves across unchanged.
