On a joint return RAP uses the couple's combined AGI and splits the payment by loan balances. Filing separately uses only your own income and dependents.
$544.45/month
10% of $110,000 joint AGI = $11,000.00 a year ÷ 12 = $916.67 − $50 × 2 dependents = $816.67 × your 66.7% share of the couple's loans = $544.45.
Your payment already covers the interest and at least $50 of principal, so RAP adds nothing this month. How the waiver and match work

Under 34 CFR 685.209(e), a married borrower who files a joint federal return has a RAP payment based on the combined AGI of both spouses. The dependents on that joint return count, at $50 a month each.
If your spouse also has eligible federal student loans, that household payment is then split by balance. You pay your share of the couple's combined eligible balances, and your spouse pays theirs. If your share comes out under $10, you pay $10.
The calculator above opens on a joint-return example: $110,000 of combined AGI, two dependents, $60,000 of loans for you and $30,000 for your spouse.
If your spouse had no federal loans, you would pay the whole $816.67.
A married borrower who files a separate return uses only their own AGI, and only the dependents claimed on their own return. The same rule covers a borrower who files jointly but certifies that they are separated from their spouse or can't reasonably access the spouse's income.
In the example above, suppose the couple's $110,000 is $70,000 for the borrower and $40,000 for the spouse:
Together the separate payments come to about $383 to $433 a month, against $816.67 on the joint return. Combining two incomes moved the couple from the 6% and 4% brackets into the 10% bracket, and RAP applies that percentage to every dollar.
Filing separately is a tax decision as well as a loan decision. Separate returns often mean a higher total income tax, and some credits and deductions are limited or unavailable. The right comparison is the yearly RAP savings against the extra tax, not the payment alone. A tax professional can price the tax side. The calculator prices the loan side: switch the filing status and compare.
Consider it again every year. A new child, a spouse's raise or paying off one spouse's loans can change the answer. RAP recalculates annually from your latest return, so the filing choice you make each spring sets the next year's payment.
IBR follows the same basic pattern. A joint return uses combined income, a separate return uses only yours, and the payment is split by balance when both spouses have loans. The difference is the family-size deduction. IBR protects 150% of the poverty guideline for the whole family, and on a joint return the family includes your spouse. For some couples that makes IBR's joint-return payment lower than RAP's. The RAP vs IBR calculator shows both for your household.
Only if you file a joint federal tax return. Then the payment is based on your combined AGI. If you file separately, or file jointly but are separated from your spouse or can't reasonably access their income, only your own AGI is used.
On a joint return, the household payment is split by each spouse's share of the couple's eligible loan balances. If your share works out below $10, your payment is $10.
Only the dependents claimed on your own return. A child can be claimed by only one spouse, so decide who claims whom with the RAP reduction in mind as well as the tax rules.
It lowers the income RAP counts, which usually lowers the payment for the spouse with loans. But filing separately can raise the couple's income tax and rule out some credits, so compare the tax cost with the payment savings before deciding.
Combining incomes can push a couple into a higher bracket, and the percentage then applies to the whole combined AGI. Two $55,000 incomes at 5% each become $110,000 at 10%, which doubles the household payment unless the couple files separately.
