How Much Child Support Will I Pay?
State-by-State Breakdown for Dads
How much child support you'll pay depends on your state's formula, both parents' incomes, the number of children, and how many overnights you have. For one child on $60K gross, most states land between $800 and $1,400 per month. But here's what nobody tells you: the difference between a Dad who knows his state's formula and a Dad who doesn't can be $300–$500/month — every single month — for 18 years.
Inside this guide you'll discover:
- ✦ The 3 child support models — and why the one your state uses can swing your payment by $400/month on the exact same income
- ✦ Why "gross income" doesn't mean what you think it means… and the deductions most Dads never claim
- ✦ The overnight threshold that triggers a parenting-time credit — even if you only have your kids on weekends
- ✦ A real-world example: how one Dad in Ohio went from $1,280/month to $840/month without making a single dollar less
- ✦ The one line on the worksheet that judges look at first — and how to make sure it's accurate
- ✦ Why paying for health insurance could save you more than you spend (and how to document it)
- ✦ The mistake that costs Dads thousands: not filing a modification when income changes
- ✦ A 5-minute exercise that shows you — right now — if you're overpaying
Let's start with the question that's probably keeping you up at night.
The Honest Answer to "How Much Will I Pay?"
You've probably Googled this three times already. And every result gave you the same useless answer: "It depends."
That's technically true. It does depend. But you deserve better than "it depends." You deserve the actual factors — the ones that move the needle — so you can look at your situation and get a real number.
Here's what actually determines your child support:
- Your gross (or net) income — depending on your state
- The other parent's income — in Income Shares states, this matters a LOT
- Number of children — more kids = higher percentage, but not proportionally
- Overnights — the single biggest lever most Dads overlook
- Health insurance and childcare costs — who's paying for what
- Other support obligations — kids from other relationships
That's it. Six inputs. Your state plugs them into a formula, and a number comes out the other side.
The question isn't whether you can understand this. You can. The question is whether you've been given the right information. Most Dads haven't.
You're working hard. You love your kids. You want to pay what's fair — not a dollar more, not a dollar less.
You just want to understand how the number is calculated… so you can make sure it's right.
That's not unreasonable. That's being a responsible Dad.
The 3 Child Support Models (and Why Yours Matters)
Every state uses one of three formulas. The model your state picked doesn't just change the math — it changes the entire game.
Model 1: Income Shares (~41 States)
This is the most common. It looks at both parents' incomes, adds them together, then splits the child support obligation based on each parent's share.
Why this matters for you: If the other parent makes good money, your share goes down. If she reports low income, your share goes up. The accuracy of both numbers is critical.
Income Shares States include:
Alabama, Arizona, California, Colorado, Connecticut, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Utah, Vermont, Virginia, Washington, West Virginia, Wyoming — and others.
Model 2: Percentage of Income (~6 States)
Only looks at the non-custodial parent's income. The other parent's income? Doesn't factor in at all.
Sounds unfair? It can be. If your ex earns $150K and you earn $50K, the formula doesn't care. It only sees your $50K.
Percentage States:
Texas, Wisconsin, Mississippi, North Dakota, Alaska, and Illinois (flat percentage model).
Model 3: Melson Formula (3 States)
Delaware, Hawaii, and Montana use this. It's Income Shares on steroids — it builds in a "self-support reserve" so neither parent drops below a basic living standard.
If you live in one of these three states, your floor is actually protected by the formula itself.
The model isn't something you choose. But knowing which one you're in? That changes everything about how you prepare.
Real Numbers: What Dads Actually Pay by State
Here's where it gets real. Let's take a Dad making $60,000/year gross, one child, and see what the numbers look like across different states. (Assuming the other parent earns $35,000 in Income Shares states.)
| State | Model | Approx. Monthly | Key Factor |
|---|---|---|---|
| Texas | % of Income | ~$1,000 | 20% of net for 1 child |
| California | Income Shares | ~$900–$1,100 | Timeshare % matters a lot |
| Ohio | Income Shares | ~$840–$1,050 | Overnight credit at 90+ nights |
| Florida | Income Shares | ~$800–$1,000 | Net income used |
| New York | Income Shares | ~$900–$1,200 | 17% of income for 1 child (+ combined calc) |
| Illinois | Income Shares | ~$850–$1,050 | Net income; overnights over 146 |
| Georgia | Income Shares | ~$800–$1,000 | Both incomes + deviations |
| Pennsylvania | Income Shares | ~$900–$1,100 | Net income; clear guidelines table |
| Wisconsin | % of Income | ~$850 | 17% of gross for 1 child |
| Delaware | Melson | ~$750–$950 | Self-support reserve protects Dad |
Look at that range. Same Dad. Same income. But the state he lives in — and how many overnights he has — swings his payment by $300–$500/month.
Over 18 years, that's $64,800 to $108,000 in difference. Just from knowing the formula.

Show Me Where I'm Losing MoneyThe Overnight Game: How Parenting Time Cuts Your Payment
This is the part most Dads don't hear about until it's too late.
In most Income Shares states, there's a magic number. It's usually somewhere between 90 and 110 overnights. Cross that threshold, and the formula kicks in a "parenting time credit" that lowers your child support.
Let's make this concrete.
Real Dad, Real Numbers
Marcus is a warehouse supervisor in Columbus, Ohio. Makes $62,000. His ex makes $38,000. They have one daughter, age 7.
Under the standard every-other-weekend schedule (4 overnights/month = 48/year), Marcus owed $1,280/month.
He rearranged his shifts. Added Wednesday overnights and alternating holidays. Got to 128 overnights. Filed for modification with documented overnight logs.
New payment: $840/month. That's $440 less — $5,280 saved per year — and he gets more time with his daughter.
Marcus didn't make more money. He didn't hire an expensive lawyer. He just learned how his state's formula works and made it work for him.
The Overnight Thresholds by State
Every state's different, but here are some common trigger points:
- • Ohio: 90 overnights triggers adjustment
- • Florida: 73 overnights (20%) for substantial time-sharing
- • California: Sliding scale — every overnight matters
- • Illinois: 146 overnights for shared parenting calculation
- • Georgia: Court discretion, but documented overnights influence deviations
- • Pennsylvania: 40%+ time (146 nights) shifts to shared formula
- • Colorado: 93 overnights activates parenting time adjustment
Here's the truth nobody says out loud: more time with your kids = less child support. And that's by design. The formula rewards Dads who show up.
You want to pay what's fair. You want to be there for your kids.
You just don't want to overpay because nobody explained the formula.
That's not greedy. That's smart. That's what a good Dad does.
The Deductions Most Dads Never Claim
Your child support worksheet has lines for deductions. Most Dads leave them blank — either because they didn't know, or because nobody told them what counts.
Here's what can reduce your gross income for child support calculations:
✅ Commonly Allowed Deductions
- ☐ Health insurance premiums for the child(ren)
- ☐ Mandatory retirement contributions (pension, union-required 401k)
- ☐ Union dues
- ☐ Child support paid for children from other relationships
- ☐ Spousal support (alimony) you pay
- ☐ Self-employment taxes (the employer-equivalent portion)
- ☐ Mandatory overtime taxes (some states exclude involuntary OT income)
⚠️ State-Dependent (Check Yours)
- ☐ Voluntary retirement contributions above mandatory minimum
- ☐ Health insurance premiums for yourself
- ☐ Extraordinary travel costs for parenting time
- ☐ Childcare costs you pay directly
- ☐ Special needs or medical expenses for the child
Real Dad, Real Savings
Kevin, electrician in Houston. Gross income: $72,000. His initial worksheet showed child support of $1,340/month for two kids.
He was paying $380/month for the kids' health insurance through his employer. $120/month in union dues. And $200/month in mandatory pension contributions.
None of that was on his worksheet. His ex's attorney used the raw $72K number.
After adding all three deductions, his adjusted income dropped to $63,600. New child support: $1,080/month. He saves $260/month — $3,120/year — just by filling in lines that were already on the form.
Gross vs. Net Income: Why This Confusion Costs Dads Money
"Your child support is based on income."
Great. Which income? The number on your offer letter? Your take-home pay? Somewhere in between?
Here's the breakdown:
- • Gross income states (majority): Start with total earnings before taxes, then allow specific deductions. Texas, California, Georgia, Ohio, Florida — most states.
- • Net income states: Start with take-home after taxes. Illinois, Pennsylvania, and several others.
- • Adjusted gross: Some states define their own version — gross minus specific items (not the same as IRS adjusted gross).
The difference between "gross" and "net" on $60,000/year can be $12,000–$18,000. That translates to $150–$250/month in child support difference.
If someone calculates your support on gross and your state uses net? You're overpaying. And nobody's going to catch that mistake except you.
What to Say When You Think the Number Is Wrong
Found an error? Think a deduction was missed? Here's what to do — without sounding aggressive or getting dismissed.
Script: Calling the Child Support Office
"Hi, my name is [your name], case number [X]. I've been reviewing my child support worksheet and I believe there may be an error in the income calculation.
Specifically, my gross income includes [health insurance / union dues / pension] deductions that aren't reflected on the current worksheet.
I have documentation — my last three pay stubs showing these mandatory deductions. What's the process to request a review or administrative adjustment?"
Calm. Specific. Documented. That's how you get results without a $5,000 attorney.
Script: Talking to Your Ex About Overnights
"Hey, I wanted to talk about spending more time with [child's name]. I've been thinking — I could take them Wednesday evenings through Thursday morning, plus the current weekends.
It would give you more free time during the week, and [child's name] has been asking to see me more. What do you think?"
Notice what's not in there? Money. The word "child support" never comes up. You're asking for time with your kid. The support adjustment is a natural consequence — but it's not the pitch.
You're not trying to avoid responsibility. You're trying to make sure the math is right.
You're not trying to shortchange your kids. You're trying to shortchange the system that overcharges Dads.
There's a difference. And you know it.
The 5-Minute Overpayment Check
Right now — before you close this tab — do this:
- Open our calculator in a new tab
- Enter your actual gross income — not last year's, not an average, your current pay
- Enter the other parent's income — best estimate if you don't know exactly
- Enter your real overnight count — including Wednesdays, holidays, summer weeks
- Compare the result to what you're currently paying
If the calculator shows a number that's $100+ less than what you're paying? You have a reason to act. Today.
When Should You File for a Modification?
Most states let you request a modification when there's a "material change in circumstances." That usually means:
- • Income change of 15%+ (up or down, for either parent)
- • Job loss or disability
- • Significant change in overnights
- • Child aging out (turning 18 or graduating)
- • New child support obligations
- • Health insurance cost changes
The biggest mistake? Waiting. Courts don't reduce support retroactively before the date you file. Every month you delay is a month of overpayment you can't get back.

Frequently Asked Questions
How much child support will I pay for one child?
For one child on $60K gross income, expect $800–$1,400/month depending on your state's model, the other parent's income, and your overnight count. Percentage-of-income states (like Texas at 20% of net) tend to be simpler. Income Shares states give you more levers to reduce it.
Does child support go up as my income goes up?
Only if someone files for a modification. Your support doesn't automatically increase with raises. But if the other parent discovers your income changed significantly, they can petition the court for an upward modification. Some states do periodic reviews every 3 years.
Can I go to jail for not paying child support?
Yes — technically. It's called "civil contempt." But judges prefer other enforcement methods first: wage garnishment, license suspension, tax refund intercepts, credit reporting. Jail is a last resort. The key is to never ignore the obligation. If you can't pay, file a modification immediately.
What if I think the other parent is hiding income?
You can request financial disclosure through the court process. During a modification hearing, both parents must provide income documentation. If you suspect cash income or unreported earnings, you can request subpoenas for bank records. The Benchmark Comparator can help you check if reported income matches industry averages.
Does child support include extras like sports and college?
Basic child support covers food, shelter, clothing, and basic needs. Extraordinary expenses — private school, sports, college — are usually separate. Some states allow judges to add these as "add-ons." Others leave it to negotiation. Get everything in writing.
