Are you wondering how much is child support in TN for 1 child, and whether you can figure it out before ever stepping into a courtroom? You’re not the only parent asking.
Whether you’re about to file for divorce, navigating a custody dispute, or simply trying to plan your finances, understanding child support in Tennessee can feel overwhelming. The numbers are real, the stakes are high, and getting it wrong can cost you more than money.
Child support isn’t just a legal formality. It shapes your child’s quality of life by covering groceries, school supplies, medical care, and childcare. Not understanding the system could lead to paying more than required or receiving less than deserved.
In this article, we’ll guide you through how Tennessee calculates child support for one child. We’ll outline typical amounts at different income levels, explain what recent law updates mean for you, and discuss what happens if payments stop.
Plus, we’ll answer parents’ most common questions, including the effect of 50/50 custody and how wage withholding works.
How Does Tennessee Calculate Child Support For One Child?
Tennessee uses what’s called the Income Shares Model to calculate child support. The core idea is simple: a child should receive the same proportion of parental income they would have enjoyed if the family had stayed together.
Here’s how it works in practice:
Both parents’ gross incomes are added together to get a combined income figure. Tennessee then uses its child support schedule. The Guidelines are published by the Department of Human Services. The base support obligation is determined by the combined income level and the number of children. Each parent’s share of that obligation is proportional to their share of the combined income.
Step-By-Step Breakdown
- Calculate each parent’s monthly gross income (wages, self-employment, bonuses, rental income, BAH, BAS, Social Security, and more all count)
- Add both sources of income to get the combined adjusted gross income
- Look up the base support obligation on the Tennessee child support schedule for one child
- Split that obligation between parents based on each parent’s income percentage
- Adjust for parenting time, health insurance premiums, and childcare costs
- Adjust for other in-home children for either parent and other children for which an obligor parent pays child support
That final number becomes the non-custodial parent’s monthly child support obligation.
What Counts As Income In Tennessee?
Tennessee casts a wide net when defining income. The guidelines include wages and salaries, tips, commissions, bonuses, self-employment income, rental income, dividends and interest, Social Security benefits, workers’ compensation, and even lottery winnings. For military, it includes BAH, BAS, and special pay, not just base pay. If money comes in regularly, there’s a good chance the court will count it.
What Is The Average Child Support Amount In Tennessee For 1 Child?
This is the question most parents want answered. The honest answer is: it depends on both income and parenting time.
Here are estimates based on standard TN guidelines, assuming the non-custodial parent does not have 50% of the parenting time, and the custodial parent earns about 40% of the combined income.
According to the Tennessee Child Support Calculator for 2026, for one child, entry-level combined incomes typically generate monthly payments of about $425 to $500, a $5,000 income produces roughly $650 to $750, a $7,500 income yields $850 to $1,000, and a $10,000 income brings payments to approximately $1,050 to $1,250.These are only estimates.
The official Tennessee child support calculator from TN DHS provides a more precise figure based on your actual income and custody details.
However, these calculators are tools that give general estimates only and do not account for all the unique factors of your case. Only a court order can set the final child support amount.
Important: Calculator results are estimates for reference only. A judge always has the final authority, and actual payments may differ from calculated amounts due to case-specific details.
How Much Child Support Will I Pay If I Make $1,000 A Week?
If you earn $1,000 a week, your monthly gross income is approximately $4,333. Using Tennessee’s guidelines for a non-high-income other parent, say, $2,000/month, the combined income is roughly $6,333/month.
If the non-custodial parent earns about 68 percent of the combined income, and has approximately 120 days per year, their share would usually be around $550.00 per month. This is a rough estimate that does not account for health insurance costs, childcare costs, other children, or other factors.
If you’re unsure how your specific income and custody arrangement will affect your obligation, speaking with a family law attorney at Taylor Dahl Law before any court date can save you from a costly surprise.

What Additional Costs Can Be Added To A Child Support Order In Tennessee?
The base support amount rarely tells the whole financial story. Tennessee’s guidelines require both parents to share additional expenses beyond the base monthly payment.
1. Health Insurance Premiums
If one parent carries health insurance for the child, that cost factors into the support calculation. The calculation may reduce the paying parent’s obligation to account for their contribution, or require the other parent to reimburse a portion of the premium.
2. Work-Related Childcare Expenses
Both parents split daycare, after-school care, and similar costs directly tied to a parent’s work schedule, adding them to the base obligation in proportion to each parent’s work schedule.
According to the U.S. Department of Agriculture, childcare alone can represent a significant portion of the cost of raising a child, making this line item one of the most significant additions to a support order.
3. Extraordinary Medical Or Educational Expenses
If a child has special medical needs, therapy requirements, or specific educational expenses not covered by insurance, a court can order both parents to contribute beyond the standard calculation. These deviations from the guideline amount require a judge’s approval and must serve the child’s best interests.
What Is The New Child Support Law In Tennessee In 2025?
Tennessee updated its child support guidelines, which are reviewed every four years as required by federal law.
According to the Tennessee Department of Human Services, the 2025 child support revisions are based on updated economic data about the cost of raising children and include changes to income schedules.
Updates also include revisions to handling checks, new guidelines for defining self-employment income, and factors to calculate income when a parent has no job.
The Tennessee child support guidelines are administered by the TN Department of Human Services and apply to all new orders and modifications filed after the effective date. According to the Tennessee Department of Human Services, the latest changes to the state’s Child Support Guidelines took effect on October 1, 2021.
If a court set your support order before these updates, the changes do not automatically apply to your case — you must request a modification.
If you believe your current support order no longer reflects your financial situation, Taylor Dahl Law can help determine if you may qualify for a modification under the current guidelines.
Can A Tennessee Child Support Order Be Modified?
Life changes. Jobs change. Custody arrangements shift. Tennessee law allows either parent to request a modification when circumstances change significantly.
When You Can Request A Modification
The most common trigger is a 15% or greater change in the support amount resulting from a recalculation under current guidelines. This can happen due to a significant increase or decrease in income, job loss, a new child from another relationship, a change in the child’s needs, or a substantial change in parenting time.
Both custodial and non-custodial parents can request a review of the child support order to seek a possible adjustment.
How To File For A Modification
You can request a modification by having an attorney file a Petition with the court. The process involves submitting updated financial documentation and attending a hearing where a judge reviews the request.
Informal Agreements Are Not Enforceable
This is critical: even if you and the other parent verbally agree to change the support amount — or put it in writing outside of court — that agreement likely carries no legal weight. You need a court-ordered modification to change your legal obligation.
Paying less than the court-ordered amount, even with the other parent’s blessing, can still result in back child support debt and enforcement action against you.

Do You Have To Pay Child Support If You Have 50/50 Custody In Tennessee?
Many parents assume that 50/50 custody means no child support is paid or received. That’s not always true in Tennessee.
Even with equal parenting time, support may apply if there’s a significant income difference. Tennessee guidelines adjust for parenting time, but equal time does not always eliminate payments.
Here’s why: the goal of child support is to ensure the child has consistent financial support in both households. If one parent earns $80,000 a year and the other earns $30,000, an equal split of parenting time doesn’t create equal financial footing for the child. The higher-earning parent may still owe a payment to help balance the child’s standard of living across both homes.
The exact amount depends on running the numbers through Tennessee’s formula with both parents’ incomes and the actual parenting schedule.
What Is The Maximum Amount Of Child Support That A Parent Can Take In Tennessee?
Federal law under the Consumer Credit Protection Act limits how much of a paycheck can be garnished for child support. In Tennessee, the limits are:
- Up to 50% of disposable earnings if the parent is supporting another spouse or child
- Up to 60% if the parent has no other dependents
- An additional 5% can be added if the parent is more than 12 weeks behind on payments.
These are maximums — the actual amount withheld depends on the support order. Wage garnishment (also called income withholding) means the employer deducts the payment from the paying parent’s paycheck before they ever see it.
Back Child Support Laws In Tennessee
Unpaid child support doesn’t disappear. A court can also hold a non-paying parent in contempt, resulting in fines or jail time.
If someone owes you back child support, Tennessee’s IV-D program through DHS can enforce the order at no cost. If you’re behind on payments due to a genuine change in circumstances, contact Taylor Dahl Law — addressing arrears proactively is far better than waiting for enforcement action.
FAQs About Child Support In Tennessee
1. Does Tennessee have a minimum child support amount?
Yes. Tennessee sets a minimum obligation of $100 per month, even if the calculated amount would be lower. Courts rarely deviate below this floor unless there are truly exceptional circumstances.
2. Does child support change if the paying parent gets a raise?
Not automatically. A raise doesn’t trigger an automatic modification- either parent must file a petition. However, if the income increase changes the guideline amount by 15% or more, a court will likely grant a modification.
3. At what age does child support end in Tennessee?
Child support typically ends when a child turns 18 or graduates from high school, whichever comes later. Support may continue beyond that in limited circumstances, such as for a child with disabilities.
Conclusion
Figuring out how much child support is in TN for 1 child depends on both parents’ incomes, parenting time, and a few additional expenses, such as insurance and childcare. Tennessee’s Income Shares Model aims to be fair, but the numbers can still surprise you — especially if your income has changed since the court entered the last order.
Calculators give you a starting point. A court order makes it real. And the difference between a rough estimate and the actual number can be hundreds of dollars a month.
Child support decisions carry long-term financial and legal consequences. Getting the calculation right the first time, or modifying an order that no longer fits your situation, is worth doing properly.
