5 Free Calculators Every Homeowner Should Use Before Selling

Five free tools that show you exactly what you'd net from a home sale, what your monthly payment would be on the next house, and where you'd save by skipping the 3% commission.

5 Free Calculators Every Homeowner Should Use Before Selling

Most people sell a home maybe two or three times in their life. The transaction is high-stakes, full of moving parts, and the actual numbers don't show up clearly until closing day, by which point any decisions you might have made differently are locked in.

These five free calculators take the guesswork out. Each one shows you a piece of the picture: what you'd net, what you'd owe, what you'd save, and what your next home would cost. Use them before you list, not after.

1. Savings Calculator

What it shows: The exact dollar difference between a traditional 3% buyer's agent commission and VroomBrick's 1% technology fee on your home's sale price.

Why it matters: This is the single biggest cost in any home sale, and it's negotiable. Most sellers don't realize there's a 2% gap between what a default commission costs and what a 1% technology fee model costs, until they see it laid out side by side.

How to use it: Enter your home value. The calculator immediately shows the 3% commission amount, the 1% fee amount, and your total savings. On a $500,000 home, that's a $10,000 difference.

2. Net Sheet Calculator

What it shows: Your projected take-home proceeds after every standard line item, agent fees, title insurance, transfer taxes, mortgage payoff, prorated taxes, and HOA fees.

Why it matters: The closing disclosure is not the time to first see what you actually net. The net sheet calculator gives you that number before you even list, so you can make decisions about pricing, concessions, and timing with full information.

How to use it: Enter sale price, your remaining mortgage balance, and a few standard inputs (state, HOA, etc.). The calculator returns your projected net proceeds with a full line-by-line breakdown.

3. Mortgage Calculator

What it shows: Your monthly principal and interest payment for any loan amount, term, and rate. Also shows total interest paid over the life of the loan.

Why it matters: Whether you're sizing your next home purchase or modeling what a different rate would do to your payment, this is the foundation. A 0.5% rate change on a $400,000 loan is roughly $120/month, over a 30-year term, that's nearly $43,000 in extra interest.

How to use it: Enter loan amount, interest rate, and loan term. Adjust the inputs to compare scenarios.

4. Offer Simulator

What it shows: How different offer scenarios compare side by side, purchase price, down payment, closing costs, monthly payment.

Why it matters: When you're deciding between two homes (or two offers on a home you're selling), the simulator lets you model the full financial picture of each scenario. It's especially useful for figuring out whether a higher-priced home with seller concessions actually beats a lower-priced home without them.

How to use it: Enter the details of two scenarios. The simulator shows them next to each other so you can compare directly.

5. Monthly Payment Breakdown

What it shows: The full all-in monthly cost of a home, principal, interest, property taxes, homeowners insurance, PMI (if applicable), and HOA fees.

Why it matters: The "mortgage payment" most people quote is just principal and interest. The actual monthly cost of owning a home is usually 25%–40% higher once you include taxes, insurance, and PMI. This calculator gives you the real number.

How to use it: Enter purchase price, down payment, rate, term, and your local property tax rate. The breakdown shows you the complete monthly cost.

How to use all five together

These calculators work as a system. A typical sequence:

  1. Run the Savings Calculator first. Confirm the cost difference between a traditional 3% buyer's agent commission and VroomBrick's 1% technology fee on your home's value. This is your biggest single decision.
  2. Then the Net Sheet. See your full projected proceeds after every cost. This is what you'd actually walk away with.
  3. Use the Mortgage Calculator and Monthly Payment Breakdown to size your next purchase based on what you'd net.
  4. Use the Offer Simulator when you're deciding between specific homes or specific offers.

The whole flow takes about 15 minutes and gives you a clear financial picture before you commit to anything.

Why we built these (and why they're free)

These calculators exist because most real estate decisions get made with vague estimates. "About $10,000 in closing costs" or "around $2,400 a month" or "we'll probably net what we want." Then the closing disclosure shows up and the actual numbers are different from the estimates by thousands of dollars.

Free calculators that show specific dollar amounts force you to make decisions on real numbers, not approximations. We'd rather have informed clients on the platform than confused ones at the closing table.
