Many homebuyers earn more than a standard hourly wage or fixed salary. Overtime, performance bonuses and sales commissions can represent a significant portion of your total compensation—but the amount deposited into your bank account is not necessarily the amount a mortgage lender can use.

When reviewing variable income, lenders generally look for three things:

1. A documented history of receiving the income

2. Evidence that the income is stable or increasing

3. A reasonable expectation that the income will continue

Understanding how this income is evaluated can help you estimate your purchasing power and avoid surprises during the mortgage process.

What Is Variable Income?

Variable income is employment income that can change from one pay period, month or year to the next. Common examples include:

• Overtime pay

• Annual or quarterly bonuses

• Sales commissions

• Production incentives

• Shift differentials

• Tips

• Performance-based compensation

This income is typically reviewed separately from your regular salary or hourly base pay. Your lender will calculate the qualifying amount based on your documented earnings history rather than simply using your most recent or highest paycheck.

How Much History Is Usually Required?

A two-year history of receiving overtime, bonus or commission income generally provides the strongest case for including it in your mortgage application.

However, having less than two years of history does not automatically mean the income cannot be used. In certain circumstances, income received consistently for at least 12 months may be considered when there are positive supporting factors.

Those factors may include:

• Remaining with the same employer

• Working in the same industry or occupation

• A consistent compensation structure

• Stable or increasing year-to-date earnings

• Employer confirmation that the income is expected to continue

The exact requirement depends on the mortgage program, documentation available and the overall loan file.

How Overtime Income Is Calculated

Overtime income is normally averaged because the number of overtime hours available may fluctuate.

A lender may review:

• Your current year-to-date overtime earnings

• Overtime reported on previous W-2s

• Recent pay statements

• Your history with your employer

• Whether overtime is likely to remain available

Here is a simplified example:

• Previous year’s overtime: $12,000

• Current year-to-date overtime through six months: $6,600

• Total overtime reviewed: $18,600

• Total period reviewed: 18 months

The estimated qualifying overtime income would be:

$18,600 ÷ 18 months = $1,033 per month

That amount may then be added to the borrower’s qualifying base income.

This is only a simplified illustration. The lender must also evaluate the income trend and determine whether the overtime has remained stable.

What Happens if Overtime Is Declining?

Declining overtime can affect the amount a lender is willing to use.

For example, suppose you earned:

• $18,000 in overtime two years ago

• $12,000 last year

• An annualized pace of $7,000 this year

A lender may not simply average all three periods and use the result. The decline must be evaluated to determine whether your current overtime has stabilized.

Depending on the circumstances, the lender may use a lower recent average or may be unable to use the overtime income until a stable pattern has been established.

This is why applying based only on your previous year’s total income can produce an inaccurate estimate of your homebuying power.

How Bonus Income Is Calculated

Bonus income may be paid monthly, quarterly, annually or according to a performance-based schedule. The lender must first determine how frequently the bonus is paid before converting it into a monthly qualifying amount.

For example, an annual bonus of $12,000 does not usually create $12,000 of additional monthly income during the month it is received. Instead, it may be converted to an estimated monthly amount:

$12,000 ÷ 12 months = $1,000 per month

The lender will then compare that amount with previous bonus earnings and current year-to-date documentation.

A bonus may be easier to use when:

• It has been received consistently

• The amount is stable or increasing

• It is part of an established compensation plan

• The employer indicates that bonuses are expected to continue

A one-time signing, retention or special performance bonus may be treated differently because it may not be recurring.

How Commission Income Is Calculated

Commission income is commonly earned by sales professionals, recruiters, account executives, real estate professionals and other performance-based employees.

When commission income fluctuates, the lender will generally calculate an average using the documented period of earnings.

Consider this simplified example:

• Previous year’s commission income: $72,000

• Current year-to-date commission through six months: $39,000

• Total commission income: $111,000

• Total period reviewed: 18 months

The estimated qualifying commission income would be:

$111,000 ÷ 18 months = $6,167 per month

Any fixed base salary would normally be evaluated separately and then added to the qualifying commission income.

The lender will also examine whether commission earnings are stable, increasing or decreasing. A strong current month does not necessarily offset a broader downward trend.

Gross Income vs. Take-Home Pay

Mortgage qualification is generally based on eligible gross income before taxes and payroll deductions—not the amount deposited into your bank account.

For example, deductions for the following items usually do not reduce the gross amount shown on your pay statement:

• Federal income taxes

• Social Security and Medicare

• Health insurance

• Retirement contributions

• Other voluntary payroll deductions

However, the income must still meet the applicable requirements for history, stability and continuance.

What Documents Will You Need?

The specific documentation depends on the loan program and how your employer reports your compensation. Commonly requested items include:

• Recent pay statements

• W-2 forms

• A written or electronic verification of employment

• A year-to-date earnings breakdown

• Documentation separating base pay, overtime, bonuses and commissions

• Personal tax returns when required

• An employer explanation of an unusual increase or decrease

Providing complete documentation early can help your lender identify discrepancies before you make an offer on a home.

Can You Use Income From a New Job?

Starting a new job does not necessarily prevent you from qualifying for a mortgage. However, variable income from a new position can be more difficult to use than a fixed salary.

The lender may consider:

• Whether the new position is in the same industry

• Your previous history of earning similar compensation

• How long you have received the new overtime, bonus or commission income

• Whether the new compensation structure is guaranteed or performance-based

• Whether the income can reasonably be expected to continue

A new base salary may be usable even when there is not yet enough history to include the variable portion of the compensation.

How to Strengthen Your Mortgage Application

You can make the income review process easier by taking a few steps before applying:

• Save your final pay statement from each year.

• Keep copies of your W-2 forms and tax returns.

• Avoid changing compensation structures immediately before applying when possible.

• Ask your employer for a breakdown of base pay and variable earnings.

• Inform your loan officer about recent promotions, raises or temporary reductions.

• Get preapproved before setting your maximum home-shopping budget.

Do not assume that all overtime, bonuses or commissions will automatically be counted. A proper income review should be completed before you rely on that income to qualify.
