Income Calculator
Web-based Income Calculator now available
Use Income Calculator right from our website to gain more certainty of loan quality by quickly and accurately calculating income for self-employed borrowers. Launch App.
Calculating income for self-employed borrowers is not easy and can be time consuming and complicated for even the most seasoned originators. With a growing workforce of self-employed borrowers, and multiple options available, originators need a clear way to calculate income that’s both accurate and efficient. With Fannie Mae’s latest solution, we offer a new way to calculate income that increases the certainty of the calculation and helps reduce cycle time.
Available through a free web interface or an automated integration with a partnering technology service provider (TSP), Income Calculator can help:
- Easily calculate income for self-employed borrowers.
- Maximize the borrower’s income by utilizing allowable add-backs not found in 4506-C tax return transcript data, which may result in lower DTI due to higher income being calculated.
- Determine the qualifying monthly income before submitting to DU.
- Originate with confidence – we offer enforcement relief of reps and warrants on the income calculation.
Income Calculator Availability
Every day, 24 hours a day, except from 1 a.m. to 5 a.m. ET the first and third Sundays each month due to maintenance.
How Income Calculator works
1. Borrower provides lender with tax returns during the application process.
2. Lender inputs borrower tax return data into Fannie Mae’s Income Calculator web interface. No NPI is collected.
3. Income Calculator generates an immediate response. The Findings Report is displayed to the originator on the web interface.
4. Lender reviews the Income Calculator Findings Report, paying careful attention to the documentation and data integrity messages.
5. Lender retains the Findings Report in the loan file.
