Quick Answer
On a $900,000 home, a traditional 3% listing commission is about $27,000. Under SnapDwell's flat-fee model, the listing-side fee is $12,500, a difference of $14,500.
On a $1,400,000 home, a traditional 3% listing commission is about $42,000. Under SnapDwell's flat-fee model, the listing-side fee is $20,000, a difference of $22,000.
This calculator helps San Diego sellers compare those listing-side costs using estimated sale price scenarios.
What this page is designed to solve
Most sellers want to answer a simple question:
How much will it cost to sell my home?
The answer depends on several factors, including:
- The final sale price of the home
- The listing fee structure
- Buyer-agent compensation (if offered)
- Typical closing costs
This calculator helps you compare different listing models so you can better estimate your potential net proceeds.

How the Calculator Works

Why San Diego Sellers Use Commission Calculators
In San Diego, home values are high enough that percentage-based commissions can become a major selling cost. Even a small change in fee structure can affect seller proceeds by thousands of dollars.
That is why many sellers compare traditional percentage commissions against flat-fee listing models before deciding how to list.
Traditional Percentage vs Flat Fee
Traditional percentage-based commission
Many agents charge a percentage of the final sale price.
For example, a 3% listing commission increases as the sale price increases.
Flat-fee listing model
Flat-fee brokerages charge a fixed listing fee based on the home's value range.
Instead of increasing with the sale price, the cost stays predictable within each pricing tier.
This structure can make it easier for sellers to estimate their costs before listing.
Why sale price matters
Real estate commission usually scales with the sale price when using a percentage-based model.
Here is a simple example.
| Scenario | Sale Price | Listing Model A (3%) | Listing Model B (Flat Fee) | Listing-Side Difference |
|---|---|---|---|---|
| Scenario A | $900,000 | $27,000 | $12,500 | $14,500 |
| Scenario B | $1,100,000 | $33,000 | $15,000 | $18,000 |
| Scenario C | $1,400,000 | $42,000 | $20,000 | $22,000 |
As the sale price increases, percentage-based commissions increase as well.
Flat-fee models typically remain stable within defined pricing tiers.
Keep listing costs and buyer-agent compensation separate
Many sellers combine all costs into one number too early.
It is often clearer to compare these decisions separately:
- Listing-side fee model (percentage vs flat fee)
- Buyer-agent compensation strategy
- Estimated closing costs
Separating these factors makes it easier to understand how each decision affects your final net proceeds.
Tier-boundary planning in flat-fee models
If your expected sale price is close to a pricing tier boundary, it can be helpful to compare both outcomes.
For example, you may want to estimate results for:
- A slightly lower sale price
- Your expected price
- A higher sale price
This helps prevent surprises during negotiations or when reviewing offers.
Common mistakes sellers make when comparing commission
When evaluating different listing models, sellers often:
- Look at only one possible sale price
- Combine multiple fees into one unclear number
- Ignore how percentage commissions increase with price
- Compare models using different assumptions
A clearer approach is to evaluate multiple price scenarios using consistent assumptions.
