How the calculation works
Understand the formula before relying on the result
Measure income trend
The latest adjusted year is compared with the prior adjusted year to identify growth or decline.
Apply a planning method
Users may select a two-year average, the lower of the average and latest year, or the latest adjusted year.
Stress the estimate
An optional haircut can model more conservative lender treatment before converting the result to monthly income.
Interpret the result
Tax income and mortgage income differ
A lender may accept, limit, or reject add-backs and may use corporate, personal, bank-statement, or stated-income approaches.
Declining income matters
A lower latest year can lead to reduced usable income or a request for current-year support.
Ownership matters
Only the supportable borrower share should be used unless a lender accepts income from another entity or guarantor.
Documentation controls
Notices of Assessment, T1 Generals, T2125 schedules, financial statements, corporate returns, bank statements, and accountant letters may all affect treatment.
Common mistakes
- Using business revenue as personal qualifying income.
- Adding back every non-cash or discretionary expense without lender support.
- Ignoring declining revenue, margins, or current-year performance.
- Using 100% of income despite partial ownership.
- Assuming one lender's program applies across the market.
What lenders review
- Business tenure, industry, ownership, and operating structure.
- Two or more years of personal and business tax documents.
- Net income, gross revenue, margins, add-backs, and retained earnings.
- Current-year financial statements and bank statements where required.
- Credit, liquidity, down payment, property, and overall debt-service ratios.
Planning tips
- Separate gross revenue, net income, salary, dividends, and shareholder withdrawals.
- Document each proposed add-back with the source statement and rationale.
- Run both the two-year average and lower-of methods.
- Prepare current-year interim statements before applying.
- Compare the income result with the Affordability and Stress Test calculators.

Frequently asked questions
Questions about this calculation
What income do self-employed borrowers use?
There is no single universal figure. Lenders may use reported net income, supported add-backs, salary and dividends, corporate financial statements, or alternative documentation under a specific program.
What are eligible add-backs?
They are expenses a lender may consider non-recurring, non-cash, or otherwise acceptable to add back. Acceptance and percentage treatment vary by lender.
Why use the lower of average and latest year?
It provides a conservative sensitivity when income is declining and avoids letting an older stronger year overstate the current earning level.
Can current-year income be used?
Sometimes, particularly to support stability or growth, but lender documentation and policy determine whether it supplements or replaces historical income.
Does this calculator determine approval?
No. It estimates one component of underwriting and does not assess credit, debts, down payment, property, stress testing, or lender-specific rules.
