Introduction

The most common question from people considering Chapter 13 bankruptcy is simple: how much will I have to pay each month?

The answer depends on a concept called disposable income — the amount remaining after allowed living expenses are deducted from the debtor's income. This calculation drives the Chapter 13 plan payment and determines how much unsecured creditors receive.

Understanding how disposable income works helps debtors prepare for Chapter 13 and avoid surprises during the process.

What Disposable Income Means

In Chapter 13, disposable income is defined as the debtor's current monthly income minus reasonably necessary expenses.

The bankruptcy court does not use a simple "income minus bills" calculation. Instead, it applies a structured formula that accounts for:

The resulting figure determines both the monthly plan payment and the plan duration.

Income Calculation

All sources of household income are considered, including:

The court typically looks at the debtor's average income over the six months before filing to establish current monthly income.

Expense Categories

The bankruptcy code allows deductions for reasonably necessary expenses. These are generally divided into:

Housing

Transportation

Food and Household

Healthcare

Other Necessary Expenses

Above Median vs Below Median Income

The income level relative to the Texas median determines which expense standards apply.

Below Median Income

Debtors below the Texas median may use their actual expenses when calculating disposable income. This provides more flexibility and often results in lower plan payments.

Below-median debtors may also propose shorter plans — as few as 36 months.

Above Median Income

Debtors above the Texas median must use IRS standardized expenses for certain categories. These standardized amounts may be higher or lower than actual expenses, depending on the debtor's circumstances.

Above-median debtors are generally required to commit to a 60-month plan.

What Disposable Income Means for Creditors

The disposable income calculation determines how much unsecured creditors receive through the plan.

The Best Interest Test

Unsecured creditors must receive at least as much through the Chapter 13 plan as they would receive in a hypothetical Chapter 7 liquidation.

The Best Efforts Test

Above-median debtors must commit all projected disposable income to the plan for the full 60-month period.

If disposable income is zero or very low after expenses, unsecured creditors may receive little or nothing through the plan. This is sometimes called a zero-percent plan and is permissible in many courts.

Real Client Scenario

A client with a combined household income of $8,500 per month had total allowed expenses of $7,800 — including mortgage, car payment, insurance, utilities, food, and childcare.

Disposable income: $700 per month

This $700 was committed to the Chapter 13 plan over 60 months, totaling $42,000 in plan payments. After priority claims (taxes, attorney fees) and secured debt payments were funded, the remaining amount was distributed to unsecured creditors.

The unsecured creditors received approximately 15% of the total owed — and the remaining balance was discharged at the end of the plan.

Strategies That Affect Disposable Income

Several legitimate factors can influence the disposable income calculation.

Timing of Filing

Income is calculated based on the six months before filing. If a debtor experienced higher income earlier in that period (such as overtime, bonuses, or a higher-paying job), waiting may result in a lower calculated income.

Actual vs Standardized Expenses

Below-median debtors may benefit from using actual expenses, which can be higher than IRS standards in some categories.

Voluntary Contributions

Certain expenses, such as charitable contributions and retirement savings, may or may not be allowed depending on the court and circumstances.

Changes in Circumstances

If income increases during the plan, the trustee may seek to modify the plan payment upward. If income decreases, the debtor may request a modification to lower payments.

Common Questions

What if my expenses are higher than the IRS standards?

Above-median debtors may be able to deduct actual expenses in certain categories if they can demonstrate the necessity. This often requires documentation and court approval.

Can I include a car payment in my expenses?

Yes. Secured debt payments — including car loans — are deducted when calculating disposable income.

What if I have no disposable income?

A zero-percent plan may be possible. This means all income goes to necessary expenses and secured/priority obligations, and unsecured creditors receive nothing. The remaining unsecured debts are discharged at the end of the plan.

Does my spouse's income count?

If filing jointly, both incomes are included. If filing individually, the non-filing spouse's income may still be considered for household budget purposes.

Conclusion

Disposable income is the key number that drives every Chapter 13 case. It determines the monthly payment, the plan duration, and how much creditors receive. Understanding how this calculation works — and what factors can influence it — helps debtors prepare for the process and make informed decisions about their financial future.
