Worked Example: $8,000 vs $3,000 Income, 12-Year Marriage

  1. Higher-earning spouse: $8,000/mo - lower-earning spouse: $3,000/mo - 12-year marriage, no concurrent child support.
  2. 20% of gross income: $8,000 x 20% = $1,600 - below the $5,000 statutory cap, so the guideline maximum is $1,600 per month.
  3. Duration for a 12-year marriage: up to 5 years. Note the narrow eligibility rules - most Texas divorces produce no maintenance.

Result: $1,600 per month - typical duration: up to 5 years
