Need Chapter 13 monthly payments? Use this calculator

You can see your estimated Chapter 13 monthly payment in seconds by running your income and living costs through a calculator built around disposable income, but treat that figure as a planning estimate, not a guaranteed final amount. The calculator takes your numbers and applies the core logic a trustee uses: it subtracts your allowed living expenses from your income to find the money available to pay creditors each month. That estimated payment gives you an immediate feel for whether a plan is affordable before you sit down with an attorney or file paperwork.

Because the result is an estimate, it does not yet include trustee fees, priority debts, or secured payment arrears that often raise the actual payment. The number you see is your starting point, and the following steps walk you through those extra layers so you can adjust it toward realistic territory. Even so, seeing that first estimate puts you ahead of the guessing game and lets you judge quickly whether Chapter 13 fits your budget.

Your calculator payment starts with two numbers: what you earn and what you spend to live. You'll list average monthly income from all sources - pay stubs, side gigs, benefits - and then enter reasonable living expenses like rent, groceries, utilities, and transportation. The math is simple: income minus allowed living costs equals your starting disposable income, which drives the estimated plan payment.

Don't guess here. Use bank statements and actual bills, not aspirational budgets. Underreporting costs can squeeze you later, and overreporting can draw trustee objections. If an expense varies, use a sensible six-month average and be ready to show receipts. A clean, honest snapshot gives you an estimate you can actually rely on.

Your disposable income is the real driver behind your Chapter 13 plan payment. It is not what you think you have left over at the end of the month; it is a formula-driven figure the court uses to decide what you can afford to repay. Getting this number right matters because it sets the baseline for your entire plan.

1. Start with your current monthly income (CMI). This is your average gross income from all sources over the six months before you file. Unusually high or low months get evened out.
2. Subtract allowed living expenses. Some costs use IRS national and local standards, not your actual spending. The court gives allowances for housing, food, transportation, and health care. Other costs, like mandatory payroll deductions, child support you pay, and certain actual expenses for elderly or chronically ill household members, can also be deducted.
3. The remainder is your disposable income. That remaining amount is what the court expects to go toward your plan payment, your priority debts, and your trustee fees each month.

The math can be strict. A big lease payment or a hobby your budget usually absorbs may not count as an allowed expense here. If the calculated disposable income looks higher than your real-life wiggle room, do not panic. The final payment is shaped further by priority debts you owe and the plan length you choose, which the next sections will walk through.

The payment estimate your calculator shows isn't your final plan payment until you add the trustee's cut. Trustee fees are a percentage deducted from every dollar you pay into the plan, and they quietly inflate the total amount you need to send each month.

The Chapter 13 trustee does not work for free. They collect, monitor, and distribute your payments, funded by a fee set by the U.S. Trustee Program. That fee comes straight off the top of your monthly payment before any creditors see a dime.

Here is how the math actually works on the ground:

• A typical trustee fee can run up to 10% of each payment, though the exact percentage varies by jurisdiction and decreases slightly as your total payout grows
• If your calculator shows a base payment of $1,000 based on your disposable income, the trustee fee is separate, making your real total payment closer to $1,100
• Some districts apply the fee to your total plan base, not just monthly, so a 60-month plan at $1,100 adds roughly $6,600 in fees over the life of the plan
• Your attorney usually builds this fee into the proposed payment schedule, but many bare-bones online calculators ignore it, leaving you with a false low number

When you judge whether a plan feels affordable, always run the math with the trustee fee baked in. A $900 payment might fit your budget, but $990 might not, and that gap is often where the fee lands. The figure you plug into your own budgeting is the gross payment, not the net distribution to creditors.

Yes, priority debts can force your monthly payment up beyond your disposable income and trustee fees because these claims must be paid in full over your plan length.

Without priority debts: Your payment roughly equals your disposable income plus the trustee's percentage. If you have $500 in disposable income and a 10% trustee fee, you pay around $550 each month.

With priority debts: You must add the amount needed to fully repay recent tax bills, back child support, or past-due alimony within your plan. If you owe $12,000 in priority taxes on a 60-month plan, that adds a hard floor of $200 per month ($12,000 梅 60) on top of your disposable income payment. You cannot reduce or strip these obligations, so they directly raise your minimum.

Choosing a 5-year plan instead of a 3-year plan is the single biggest lever you have to lower your estimated monthly payment, but it extends your time in bankruptcy. The math is simple: your required monthly payment is driven largely by your disposable income. Stretching the same total repayment obligation over 60 months instead of 36 months nearly cuts each payment in half, giving your budget significant breathing room.

However, a longer plan length is not always a choice. If your household income is below your state's median for a family of your size, you can typically qualify for a 3-year plan. If your income is above the median, the law generally requires a 5-year commitment, unless you can pay all allowed unsecured debts in full sooner. Your eligibility is determined by the means test, not simply personal preference.

The practical tradeoff is certainty versus speed. A 5-year plan creates a longer stretch of strict budgeting and trustee oversight, but it can make a tight budget workable or free up cash for large, necessary expenses. A 3-year plan gets you to a discharge faster but demands a much higher monthly payment for the same debt load. Use the calculator to toggle between both timelines to see the stark contrast in estimates, then verify which one you realistically qualify for first.

For anyone with irregular pay, overtime, or gig income, plugging in a single average number won't fly. The trustee needs to see a realistic, defensible monthly figure, and your payment hinges on that disposable income snapshot.

Instead of guessing, use the calculator to run three quick scenarios: a low month, an average month, and a high month. This stress-tests what you can truly afford over a five-year stretch when pay swings are guaranteed. For spotty income, the safest approach is to base your estimate on a conservative, provable average, often using six months of bank statements or tax returns.

• A low-month test shows the bare-minimum payment you can consistently cover without falling behind.
• An average-month test gives you the most likely number the trustee will push for.
• A high-month test exposes whether extra overtime or a strong quarter could accidentally inflate your plan payment beyond what's sustainable once work slows down.

The bottom line is consistency. If the calculator shows your projected payment eats up nearly all disposable income in an average scenario, you need to either adjust expenses or plan for a leaner budget, because a single slow month can sink the entire plan.

When you owe back payments on secured assets like a house or car, your Chapter 13 plan payment must account for those arrears. The calculator bumps up your monthly amount to catch you up on what you would otherwise lose.

• Mortgage arrears and car loans: If you are behind, the total past-due amount gets divided across your plan length. That means a portion of each monthly payment goes directly toward saving your home or vehicle.
• Recent tax debts: Back income taxes owed to the IRS or state typically get treated as priority debts. They do not eat into your disposable income calculation, but they sit on top of it and raise your total payment.
• Older tax debts: Some older tax liabilities can be treated like general unsecured debt and paid only what your remaining disposable income can cover, not in full. The exact cutoff date varies, so flag this with your attorney.
• Loan cramdowns: If your car loan is older than 910 days, you may only need to pay the current replacement value, not the full balance. The calculator can adjust for that secured claim split only if you manually input the reduced figure.
• Post-petition payments: Your ongoing monthly mortgage and car payment are already in your living-costs line, not here. This section is strictly for clearing the backlog.

The calculator assumes you must cure these defaults to keep the asset. If you plan to surrender the car or house, remove that arrears entry entirely.

Your plan payment can be recalculated mid-case if your income changes significantly, but a small bonus or temporary pay cut usually doesn't automatically alter it. The math turns on whether your disposable income shifts enough to justify a formal modification with the court.

A permanent pay cut that shrinks your disposable income below the original plan amount is a reason to request a lower payment through your attorney. Conversely, a large, sustained raise or recurring bonus typically means the trustee will ask for the payment to go up, since more disposable income is available for creditors. The key test is whether the change is lasting, not a one-time windfall or a short dip. Always report material income swings to your lawyer immediately because hiding a bonus can put your case at risk even if the payment didn't change.

The number this calculator gives you is a well-informed starting point, not a locked-in sentence. Only the bankruptcy judge and your assigned trustee can set your final monthly payment after reviewing every detail of your case.

Think of the result as a strong ballpark figure. It uses your stated income, living costs, and debts to project your disposable income. However, small differences in how the court interprets allowed expenses, the exact trustee fee for your district, or the treatment of a priority debt can shift the final number slightly up or down.

For example, you might plug in a $600 monthly grocery expense, but the trustee may challenge that figure and use a local standard instead, nudging your payment higher. Or, you may forget to list a minor car repair cost that the court ends up allowing, which nudges it lower. The calculation gets you close enough to plan realistically, but it cannot replicate your trustee's final audit. Always view the figure with a small margin for adjustment.
