Gift of Equity Analysis
What Is a Gift of Equity Calculator?
A Gift of Equity Calculator measures the difference between a home’s fair market value and the price paid by the buyer. A positive difference is treated as a gift of equity. The calculator combines that gift with any additional cash down payment and estimates how much of the appraised value is covered before financing.
A gift of equity calculator subtracts the actual sale price from the home’s fair market value. It then uses the result as part of the buyer’s effective down payment. This tool also estimates the mortgage amount, seller’s capital gain, available annual gift exclusion, and gift amount above that exclusion.
This calculator is designed for buyers, sellers, family members, and other parties reviewing a below-market home sale. Its results are estimates based only on the values entered. It does not determine loan approval, tax liability, eligibility for tax exclusions, or whether a lender will accept the transaction.
How the Gift of Equity Formula Works
The calculator first finds the gift of equity by subtracting the actual sale price from the fair market or appraised value. A negative result is changed to zero.
It then adds any cash down payment to the gift of equity:
The effective down payment percentage and required mortgage amount are calculated from the appraised value:
The displayed seller capital gain is the sale price minus the adjusted cost basis. A loss is not shown because negative results are changed to zero.
The calculator uses a fixed annual gift tax exclusion of $18,000 for each donor:
- F is the fair market or appraised value.
- S is the actual sale price.
- C is the additional cash down payment.
- B is the seller’s adjusted cost basis.
- N is the number of donors.
Worked Example
Assume a home is appraised at $350,000 and sold for $280,000. The buyer adds no cash down payment. The seller’s basis is $150,000, and there is one donor. The gift is $350,000 minus $280,000, or $70,000. The effective down payment is $70,000, equal to 20.00% of the appraised value. The mortgage estimate is $280,000. The displayed capital gain is $130,000. With an $18,000 exclusion, the calculator flags $52,000 as requiring Form 709 reporting.
How to Use the Gift of Equity Calculator: Step by Step
- Enter the property’s Fair Market Value / Appraised Value. This value must be greater than zero for the calculator to produce results.
- Enter the Actual Sale Price to Buyer. If the sale price equals or exceeds the appraised value, the calculator reports no gift of equity.
- Enter the buyer’s Additional Cash Down Payment. Enter zero if the buyer is not contributing extra cash.
- Enter the Seller’s Adjusted Cost Basis. The calculator subtracts this amount from the sale price to estimate the displayed capital gain.
- Enter the Number of Donors. The field is designed for one or two donors, such as one seller or a married couple making the gift.
- Select Calculate to view the analysis. Select Reset to clear every input and hide the results.
The main result is the total gift of equity. The breakdown shows how the gift and cash contribution affect the buyer’s effective down payment and mortgage estimate. It also shows the seller’s calculated gain, the total annual exclusion used by the tool, and the gift amount above that exclusion.
What Your Gift of Equity Calculator Results Mean
Buyer Financing Results
The gift of equity represents the discount between the appraised value and sale price. The calculator treats this amount as part of the buyer’s down payment. Any additional cash entered is added to it. The down payment percentage is based on the appraised value, not the lower sale price.
| Displayed Result | How the Calculator Determines It |
|---|---|
| Total Gift of Equity | Appraised value minus sale price, with a minimum of zero |
| Effective Down Payment | Gift of equity plus additional cash down payment |
| Down Payment Percentage | Effective down payment divided by appraised value |
| Required Mortgage Amount | Appraised value minus effective down payment, with a minimum of zero |
| Seller’s Capital Gain | Sale price minus adjusted cost basis, with a minimum of zero |
| Total Annual Exclusion | Number of donors multiplied by $18,000 |
| Amount Requiring Form 709 | Gift amount above the calculated annual exclusion |
Important Limits of the Estimate
The mortgage result is a simplified estimate. It does not include closing costs, prepaid expenses, lender fees, interest rates, loan terms, mortgage insurance, property taxes, homeowners insurance, or lender-required adjustments. A lender may calculate the final loan amount differently and may require specific gift documentation.
The tax section is also limited. The calculator uses a fixed $18,000 annual exclusion for each donor and does not ask for the tax year, number of recipients, previous gifts, gift splitting, lifetime exemption use, filing status, or other tax details. An amount shown as requiring Form 709 is a reporting estimate, not an estimate of tax owed.
The on-page calculator note states that qualifying sellers may be able to exclude up to $250,000 of gain if single or $500,000 if married when the home was their primary residence for two of the previous five years. The calculator does not test those conditions or apply that exclusion to its displayed capital gain.
Frequently Asked Questions
What is a gift of equity?
A gift of equity is the difference between the property’s fair market value and the lower price paid by the buyer. In this calculator, the difference cannot be negative. If the buyer pays the appraised value or more, the displayed gift of equity is zero.
How do I calculate a gift of equity?
Subtract the actual sale price from the home’s fair market or appraised value. For example, a $400,000 appraised value and a $325,000 sale price create a $75,000 gift of equity. If the sale price is higher than the appraised value, this calculator uses zero.
Does a gift of equity count as a down payment?
This calculator treats the gift of equity as part of the buyer’s effective down payment. It adds the gift to any additional cash down payment entered. Actual lender treatment may depend on the loan program, property appraisal, relationship between the parties, documentation, and underwriting requirements.
How does the calculator estimate the mortgage amount?
The calculator subtracts the total effective down payment from the home’s appraised value. The effective down payment includes both the gift of equity and additional buyer cash. If that total exceeds the appraised value, the displayed mortgage amount is limited to zero rather than becoming negative.
Why does the calculator show an amount requiring IRS Form 709?
The calculator compares the gift of equity with a fixed annual exclusion of $18,000 per donor. Any excess is displayed as the amount requiring Form 709 reporting. This result does not mean the same amount is immediately taxable, and it does not account for other gifts or lifetime exemption rules.
How is the seller’s capital gain calculated?
The displayed capital gain equals the actual sale price minus the seller’s adjusted cost basis. If the basis is higher than the sale price, the calculator displays zero instead of a loss. It does not subtract selling expenses or apply a primary residence exclusion, depreciation, or other tax adjustments.
How accurate is this gift of equity calculator?
The arithmetic matches the values entered and the formulas built into the tool. Real financing and tax results may differ because the calculator does not evaluate lender policies, closing costs, tax-year changes, filing history, ownership details, residence qualifications, or professional appraisals. Use the results as planning estimates only.
