Calculation Type

Investment Income

Interest, dividends, capital gains, and K-1 distributions — averaged, tested for continuance, and separated from retained earnings.

Investment income can qualify a borrower — or disqualify a scenario — depending on how it's read. Interest and dividends on Schedule B need a two-year average and a continuance check against the underlying assets. Capital gains are highly variable and only count when a consistent history and remaining assets support the future run rate. K-1 distributions must be separated from retained earnings that the borrower can't actually access.

IncomeCalculator.com reads Schedule B, the capital gains schedules, and K-1s together with the supporting asset statements, applies the required averaging and continuance tests, and returns a defensible monthly investment income figure — with the assets that support it clearly identified.

What to upload

  • Personal tax returns (Form 1040) with Schedule B, Schedule D, and Form 8949
  • K-1s for each entity the borrower has ownership in
  • Recent brokerage and bank statements supporting the reported income
  • 1099-INT, 1099-DIV, and 1099-B forms
  • Documentation of any capital gain events and remaining asset base

How the calculation works

1

Separate income streams

Interest, dividends, capital gains, and K-1 distributions are each identified from the tax return and the underlying 1099s, then evaluated on their own rules.

2

Average and test continuance

Interest and dividends are averaged over two years and tested against remaining assets. Capital gains require a consistent multi-year history and enough remaining asset base to project forward.

3

Handle K-1 distributions vs. retained earnings

For pass-through entities, only distributed income the borrower can access is counted. Retained earnings that stay inside the entity are excluded from qualifying income.

Supported programs

Conventional, FHA, VA, and Non-QM. Continuance rules and averaging windows vary by program and are applied automatically.

Common questions

How are capital gains treated?

Capital gains only count with a consistent two-year (or longer) history and a remaining asset base that supports the future run rate. Sporadic gains from a one-time sale are typically excluded.

Do interest and dividends need a continuance check?

Yes. Both are averaged over two years and tested against the underlying assets to confirm the income is likely to continue for the required period.

How are K-1 distributions handled?

Only distributed income the borrower actually receives counts as investment income. Retained earnings inside a partnership or S-corp are not counted unless the borrower has full access and the entity's cash flow supports it.
