There's no amount of money that you can get for donating a kidney or other organs.
Getting paid for and selling or purchasing of human organs including the kidneys is illegal in the United States.
So nobody gets compensation or money directly for donating of a kidney or other organs like you could with donating plasma.
Although you can get some assistance and helps through programs to help to cover the costs of the kidney donation like any medical expenses, travel, lost wages during recovery, lodging and even get tax credits in some states for donating a kidney or other organs.
The recipient's of the kidney health insurance often covers the cost of the kidney donation for the person donating the kidney including the hospitalization, follow up care and surgery.
Some programs like the National Living Donor Assistance Center or NLDAC, provide for financial assistance to organ donors for lost wages during the recovery period and they along with other organizations may also provide assistance with any travel and lodging expenses for the organ donor as well as their families.
And some states will also give tax credits to kidney donors.
The maximum reimbursement for travel, lodging and any dependent care costs for kidney donors is $600.00.
