Reported earnings, owner pay, claimed adjustments, the portion you want to credit, chosen earnings multiples and any separately priced assets. Include the asking price if available.
What you keep
Adjusted earnings, a low-to-high value range, an asking-price comparison and an opening-offer calculation. This explores value assumptions; a purchase ceiling and a written LOI answer different questions.
Keeping & returning

When this helps.

You have earnings figures and seller adjustments to examine, and you want to understand what supports an offer range. Try different assumptions before a seller conversation, an adviser review, or preparation of an offer.

You supply the earnings adjustments and valuation multiples. The tool shows their effect; it does not determine which assumptions are justified.

Bring the assumptions you want to examine.

  • Reported annual net profit, the owner’s salary and benefits, and claimed one-time or discretionary adjustments.
  • The percentage of claimed adjustments you want to credit in this scenario.
  • Your low and high earnings multiples, plus any inventory or assets priced separately.
  • The seller’s asking price, if available, and the percentage of low-end operating value to use for an opening-offer scenario.

What you receive.

  • The Business Valuation & Offer Builder HTML application and a plain-English quick-start guide.
  • A calculation of seller’s discretionary earnings (SDE) using the adjustments you enter.
  • Low and high values, a midpoint, and an opening-offer calculation based on your assumptions.
  • A comparison of the asking price with your range and its implied earnings multiple.
  • A valuation summary you can copy into your own notes or share for review.

Open it and keep the summary.

Extract the ZIP and open business-valuation-offer-builder.html in your desktop browser. It works offline without Excel, installation, or a product account. Load example provides fictional figures to try before entering your own.

Entries are not saved between sessions. Use Copy valuation and paste the summary into a document you keep before closing or reloading. Show valuation text gives you a selectable version if automatic copying is unavailable. The summary is a record to read; it cannot be imported to restore the calculator.

Make the assumptions visible.

A confidence percentage is a scenario input, not evidence that an adjustment is valid. This tool does not supply market comparables, perform an appraisal, or prepare a legal offer document. Have the earnings, multiples, and transaction terms reviewed before relying on the result.

Valuation & Offer Builder / Worked example

See what supports the range.

Trace one offer calculation from reported earnings through credited adjustments to an assumed value range.

01 / The earnings

Credit an adjustment deliberately.

The seller reports $70,000 net profit, $40,000 owner salary and benefits, and $20,000 of other claimed adjustments. For this scenario, the buyer credits half of those other adjustments.

Net profit$70,000reported
Owner pay+ $40,000entered
Adjustments+ $10,00050% credited
$120,000$70,000 + $40,000 + ($20,000 × 50%)
A 50% credit is a scenario input, not a confidence measurement or evidence that the adjustment is valid. Check the underlying records and replacement costs.
