How the Self-Employed Income Calculator Works

A plain-English walkthrough of what the Self-Employed Income Calculator asks for and how it turns those inputs into a result.

By Onias Derilus, Mortgage Capital · NMLS# 1859012 · Last Updated: June 2026

It estimates the qualifying income a lender will use from your tax returns by averaging net business income and adding back non-cash deductions like depreciation.

How It Works, Step by Step

The calculator averages your net income across the documented years, adds back deductions that did not cost cash — depreciation, depletion, and similar — and applies your ownership share to produce a monthly qualifying figure.

Florida's no-state-income-tax environment and entrepreneurial economy mean a large share of buyers are self-employed. Lenders here are well-versed in self-employed underwriting, but they still want two years of returns and consistent income, so plan your home purchase around your filing history.
