About this calculator
Estimates spousal support in Kansas using that state's advisory guideline (duration and amount tied to marriage length). Enter each spouse's monthly net income; the tool applies the percentage formula associated with Kansas's guideline and shows the resulting monthly amount. This is an estimate only, not legal advice — actual awards depend on the specific court, county guideline worksheets, and judicial discretion, and a judge may deviate from the guideline for good cause.

FAQ
What is the Kansas formula for alimony/spousal support?
advisory guideline (duration and amount tied to marriage length).
Is Kansas's alimony guideline mandatory?
Kansas courts commonly reference an advisory formula (roughly 20% of the difference in gross incomes, capped by marriage-length-based duration), but it is a judicial guideline, not a statute, so courts can and do deviate.
Is Kansas spousal support guaranteed at this amount?
This is an estimate only, not legal advice — actual awards depend on the specific court, county guideline worksheets, and judicial discretion, and a judge may deviate from the guideline for good cause.
Does this account for taxes on alimony?
No — since 2019, alimony is not federally tax-deductible for the payor or taxable income for the recipient for divorces finalized after 2018; this estimate is a pre-tax guideline figure only.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
