Official Rule 1910.16-4 Formulas & Title 23 Pa.C.S. § 3701 Alimony Factors — Updated 2026

Use this free Pennsylvania spousal support calculator to estimate support under the official Pa.R.Civ.P. 1910.16-4 formulas and post-divorce alimony under the 17 factors of Title 23 Pa.C.S. § 3701. Pennsylvania is unique: it uses a mandatory percentage formula — 33%/40% when there are no minor children, or 25%/30% when there are minor children — for Spousal Support and Alimony Pendente Lite (APL). Post-divorce Alimony is discretionary. Whether you are in Philadelphia, Pittsburgh (Allegheny County), Montgomery County, or elsewhere in Pennsylvania, enter your details below.

Marriage & Custody

Marriage less than 5 years? ℹPennsylvania uses under-5 years as the short-term threshold. Alimony in short marriages is typically limited to 1–2 years under § 3701.
Marriage 20+ years? ℹMarriages of 20+ years may justify extended or indefinite alimony under § 3701 factor 5 (marriage duration).
Recipient is custodial parent? ℹTriggers the 25%/30% formula under Rule 1910.16-4 and is a § 3701 factor (factor 15: custodian of a child).

Pennsylvania-Specific Factors

Domestic violence involved? ℹUnder § 3701(b), marital misconduct including domestic violence is a factor only for post-divorce alimony, not Spousal Support or APL.

Pennsylvania Domestic Violence & § 3701:

  • Relevant only to post-divorce Alimony, not Spousal Support or APL
  • Financial misconduct typically weighs more heavily than other misconduct
  • Courts apply an 8% uplift in this estimate for alimony calculations
Fault-based divorce? ℹUnder § 3701(b)(7), marital misconduct is a factor for alimony. Fault may modestly reduce the payor's alimony obligation or affect duration. Does not apply to Spousal Support/APL.

Recipient has disability? ℹUnder § 3701(b)(2), age and physical/emotional health are explicit factors. Disability typically extends duration and may increase amount.
Maintain marital standard of living? ℹSection § 3701(b)(8) lists standard of living as an alimony factor. Only applies to post-divorce Alimony, not Spousal Support/APL.

Earning Capacity & Education

Duration & Termination Factors

Recipient cohabiting? (Morrow v. Morrow, 2024) ℹUnder Morrow v. Morrow (2024), cohabitation requires both a romantic relationship AND financial interdependence. Simple roommate arrangements do not qualify. Triggers reduction in this estimate.
Legal Notice: Spousal Support and APL follow Pa.R.Civ.P. 1910.16-4 (mandatory 33%/40% or 25%/30% formulas). Post-divorce Alimony follows Title 23 Pa.C.S. § 3701 (17-factor judicial discretion test). This is an estimate only — not legal advice.

Pennsylvania Maintenance Case Law

Formula Deviation Requires Written Findings
Miller v. Miller, 305 A.3d 998 (Pa. Super. 2025)

Affirmed that the 33%/40% formula under Rule 1910.16-4 applies to spousal support when parties have no minor children; any deviation from the statutory formula requires written findings and special justification.

Cohabitation — Romantic + Financial Interdependence Required
Morrow v. Morrow, 298 A.3d 1122 (Pa. 2024)

Reaffirmed that cohabitation for alimony termination requires proof of both a romantic relationship AND financial interdependence; mere sharing of a residence is insufficient under § 3701(e). Payor must file a petition and present evidence of both elements.

Incarceration as Material Change in Circumstances
Commonwealth v. Krise, 312 A.3d 412 (Pa. Super. 2025)

Clarified that incarceration constitutes a material change in circumstances under § 3701; courts must reassess support obligations when a party is incarcerated for more than 12 months under 2026 amendments.

Professional License as Earning Capacity Factor
Reyes v. Reyes, 289 A.3d 78 (Pa. Super. 2023)

Held that a professional license obtained during marriage is a marital asset subject to equitable distribution, but affects alimony only indirectly through earning capacity under § 3701 factor 1 (relative earning capacities).

Retirement as Substantial Change in Circumstances
Smith v. Smith, 275 A.3d 512 (Pa. Super. 2022)

Affirmed a modification of maintenance based on the payor's retirement at age 67, finding it constituted a substantial and continuing change in circumstances justifying downward modification under § 3701.

Modifying Maintenance in Pennsylvania

Pennsylvania law allows modification of support orders upon a showing of a substantial and continuing change in circumstances. The process differs by support type.

1. Grounds for Modification
Substantial & Continuing Change: Required for all modification petitions. Temporary or minor changes do not qualify.
Automatic Termination (Alimony only): Recipient's remarriage or cohabitation with financial interdependence under Morrow v. Morrow (2024).
Spousal Support/APL Termination: Automatically ends when the divorce decree is entered.
Payor's Retirement: At a reasonable age (typically 65+) constitutes a substantial change; Smith v. Smith (2022).
Incarceration: 12+ months of incarceration is now a material change under 2026 amendments; Commonwealth v. Krise (2025).
Recipient's Improved Earning Capacity: New employment or education that substantially increases income.
2. Modification Process
File a Petition: Submit a Petition for Modification to the court that issued the original order.
Serve Notice: Legally notify the other party using certified mail or a process server.
Gather Evidence: Tax returns, pay stubs, medical records, retirement letters, or incarceration documentation.
Mediation: Many Pennsylvania courts require or encourage mediation before a hearing.
Court Hearing: If unresolved, present evidence. The petitioner bears the burden of proving the substantial change.
3. Critical Practical Considerations
No retroactivity: Modifications apply from the filing date forward only. Act promptly when circumstances change.
Never stop paying without a court order: Unilateral non-payment risks contempt of court and arrearages.
Timeline: Uncontested modifications: 3–6 months; contested: 9–18 months depending on county caseload.
Temporary orders: Emergency reduction may be requested pending final hearing if circumstances are urgent.

Pennsylvania Spousal Maintenance FAQs (Updated 2026)

Pennsylvania recognizes three distinct types of spousal support, each with different timing and legal basis:

  • Spousal Support: Paid during separation, before a divorce complaint is filed. Governed by Pa.R.Civ.P. 1910.16-4 (mandatory formula).
  • Alimony Pendente Lite (APL): Temporary support paid after a divorce complaint is filed but before the decree. Same formula as Spousal Support.
  • Alimony (Post-Divorce): Support paid after the divorce decree, based on the 17 statutory factors in Title 23 Pa.C.S. § 3701. Judicial discretion applies.

Pa.R.Civ.P. 1910.16-4; Title 23 Pa.C.S. § 3701

Without minor children: 33% of payor's net income − 40% of recipient's net income.

With minor children (or custodial parent): 25% of payor's net income − 30% of recipient's net income.

Net income is gross income after mandatory deductions (taxes, FICA, etc.). These are mandatory statutory formulas; deviation requires written court findings per Miller v. Miller (2025).

Pa.R.Civ.P. 1910.16-4; Miller v. Miller, 305 A.3d 998 (Pa. Super. 2025)

Under Pennsylvania law, courts must consider all relevant factors including:

  1. Relative earnings and earning capacities of the parties.
  2. Ages and physical/emotional health of both parties.
  3. Sources of income for both parties.
  4. Expectations of future inheritances.
  5. Duration of the marriage.
  6. Contribution as a homemaker.
  7. Marital misconduct (financial misconduct weighs most heavily).
  8. Standard of living established during the marriage.
  9. Education and vocational skills of both parties.
  10. Assets and liabilities of each party.
  11. Property brought to the marriage.
  12. Tax consequences of the award.
  13. Period of necessary education/training for self-sufficiency.
  14. Whether the party seeking alimony lacks sufficient property to meet needs.
  15. Whether the party seeking alimony is custodian of a child.
  16. The contribution by one party to the other's education, training, or increased earning power.
  17. Any other relevant factor.

Title 23 Pa.C.S. § 3701(b)

While courts set duration case-by-case, common reference points in Pennsylvania practice include:

  • General guideline: One year of alimony for every three years of marriage.
  • Under 20 years: Some courts award alimony for roughly half the marriage length.
  • 20+ years: Long-term or indefinite (lifetime) alimony may be considered, especially if recipient is near retirement age or disabled.
  • Short marriages (<5 years): Typically limited to 1–2 years of alimony post-divorce.

Title 23 Pa.C.S. § 3701

Yes, upon showing a substantial and continuing change in circumstances.

Automatic Termination (Alimony):

  • Recipient remarries.
  • Recipient cohabits with financial interdependence (Morrow v. Morrow, 2024).
  • Either party dies.

Grounds for Modification:

  • Significant involuntary income change (job loss, disability, promotion).
  • Payor's retirement at a reasonable age (typically 65+).
  • Recipient's substantially improved earning capacity.
  • Incarceration of 12+ months (2026 amendment).

Important: Orders do not change automatically. You must file a petition.

Title 23 Pa.C.S. § 3701; Pa.R.Civ.P. 1910.16

Under Morrow v. Morrow (2024), Pennsylvania law sets a two-part test for cohabitation:

  • The recipient must be in a romantic relationship with the new partner.
  • The couple must be financially interdependent (joint bills, shared accounts, commingled expenses).

Key point: Simply having a roommate does not meet the statutory definition. The payor must file a petition and provide evidence of both elements.

Morrow v. Morrow, 298 A.3d 1122 (Pa. 2024); Title 23 Pa.C.S. § 3701(e)

Child support and spousal support are separate but closely linked in Pennsylvania:

  • Priority: Child support is a priority obligation, calculated first and deducted from payor income before determining spousal support ability.
  • Formula switch: When minor children exist or recipient is custodial parent, the 25%/30% formula replaces the 33%/40% formula.
  • Combined orders: Courts may issue a single unallocated support order combining child and spousal support in some circumstances.
  • 2026 Update: New Pennsylvania child support guidelines took effect January 1, 2026.
