The Arizona Spousal Support Calculator is a web-based tool that provides a conservative, non-binding estimate of potential spousal maintenance (alimony) under Arizona law, using a simplified guideline model for quick planning and negotiation.

How to use the Arizona Spousal Support Calculator (Quick Guide)

This calculator is designed to give you a realistic, conservative estimate of possible spousal maintenance in Arizona. It is not a replacement for legal advice or the official court worksheet; rather it’s a practical planning tool that helps you understand how incomes, shared expenses, and marriage length can influence potential awards.

What the calculator does and why it helps

The tool collects the two parties’ monthly gross incomes, monthly indivisible household expenses (expenses that benefit the household generally), and the length of the marriage. Using a simplified model it estimates:

• A monthly payment amount (an approximate range rather than a precise order).
• A suggested duration range based on marriage length.
• A small visual that compares incomes and the estimated transfer using Plotly.js.

Arizona law requires courts to consider multiple factors and follow spousal maintenance guidelines established by the Arizona Supreme Court; those guidelines are meant to encourage self-sufficiency for the receiving spouse. The official guidance and worksheet are the controlling authorities, and actual awards may differ from this tool’s estimate.

Step-by-step: entering your numbers

1. Enter each spouse’s gross monthly income. Use pre-tax income unless you have reliable net figures.
2. Add indivisible household expenses (mortgage, utilities, insurance) — the parts that are shared and not easily assignable to one person.
3. Enter the length of the marriage in years. Courts treat shorter and longer marriages differently when determining duration of maintenance.
4. Click “Estimate” to see the calculator’s output and an interactive chart that visualizes the incomes and the estimated maintenance transfer.

The Arizona Supreme Court’s spousal maintenance guidelines emphasize that maintenance should enable the receiving spouse to become self-sufficient and often limit awards to what is necessary and time-limited. This tool mimics that spirit by producing conservative estimates.

How the estimate is calculated (simple, transparent model)

Because Arizona does not set a single arithmetic formula for every case, this calculator uses a clear, conservative approximation:

• It computes each party’s disposable household position after subtracting the requesting spouse’s share of indivisible expenses.
• The estimated monthly award is up to 30% of the net income difference between parties, limited by the payer’s ability to pay (so it won’t recommend payments that would drive the payer below basic needs).
• Duration is estimated as a fraction of the marriage length (short marriages yield short durations; long marriages may produce longer durations). This mirrors the guideline purpose: rehabilitation toward self-sufficiency rather than indefinite support. These simplifications are intentionally conservative and for planning only.

Interpreting results and common scenarios

• If incomes are very close, the model often returns a negligible or zero award — courts likewise may deny maintenance where both spouses are self-sufficient.
• If one spouse earns significantly more and marriage length is moderate or long, the estimate will show a larger monthly amount and longer suggested duration.
• The calculator does not account for complex assets, tax planning, retirement division, debts, or unusual circumstances (illness, disability, or very high incomes). For those, consult an attorney.

Tips for accurate inputs

• Use recent pay stubs or tax returns for income numbers.
• Be realistic about indivisible expenses — overcounting can inflate estimates.
• If you have sole custody of minor children, child support affects disposable income and may change maintenance outcomes; consider both together when budgeting. Arizona practice often determines maintenance before child support calculations in certain contexts.

Why Plotly.js visuals matter

The embedded Plotly.js chart shows incomes and the estimated monthly transfer side-by-side. Visual comparisons help parties and attorneys quickly see the imbalance the calculator is trying to address, which can improve negotiations and clarity during settlement talks.

When to consult an attorney and next steps

If your case involves substantial assets, retirement accounts, complex business income, disability, or unusual expenses, consult an Arizona family-law attorney as soon as possible. An attorney can run the official worksheet, review non-standard deductions, propose temporary orders during litigation, and negotiate tax-aware settlements. After you use this estimator, gather pay stubs, bank statements, tax returns, and a list of household expenses and bring them to your consultation. Save your calculator results and screenshots to speed the process.
