How it works

One line on your site. Real numbers for your movers. The lead to you.

The detail for agents and loan officers: what you paste, what a mover sees, and exactly what lands in your inbox.

Step 1

Share your calculator, two ways

Every seat includes both. Use one or the other, or both at once. We send you yours at activation.

Option 1 · On your website

Paste the embed code

Copy and paste this one line into any page of your website: a relocation page, a city page, a blog post. Don’t manage your own site? Send the line to whoever does. It’s a copy and paste, with nothing to install.

Embed code (example) · goes on your website

<script src="https://getcityproof.com/v1/cityproof.js" data-page="nashville-yourname" async></script>

Option 2 · No website changes

Share your hosted link

Your calculator also has its own address on getcityproof.com, with your branding. Put it in your email signature, social profiles, texts or follow-ups. Nobody needs to touch your website.

Hosted link (example) · lives on getcityproof.com

https://getcityproof.com/p/nashville-yourname

Either way, the calculator is branded with your name, photo and brokerage (or NMLS number and lender, for loan officers). None of CityProof’s figures or logic live on your site, your site’s styles can’t break the widget, and when figures are refreshed you change nothing.

Step 2

A mover runs their numbers

A short form under your name and photo. They enter:

Where they live now: any US city or ZIP code
Household income band
Whether they plan to rent or buy
A monthly budget or a target price
When they hope to move
Their name and email, so CityProof can send their results and the guide

Then they click submit. They see a before-and-after table of what a household like theirs keeps or pays each year in your city against where they live now: income tax, property tax and homestead rules, insurance, sales tax, and rent or mortgage, each with its source and date. Below the table, a button invites them to start the conversation with you.

What the calculator never does

Estimate a specific listing or address
Describe a neighborhood, or who lives anywhere
Rate schools
Carry political content
Let any seat, including yours, change an assumption
Send a mover’s details to anyone but the professional whose calculator they used

What they see after submitting

The before-and-after table

Here are the full sample results for one household, renting and owning. The money calculator shows the mover the version that matches their answers.

Sample

Moving from Chicago to Nashville: a household earning $85,000

Renting the typical home, per year
Line	Chicago	Nashville	Difference
Rent, typical home, 12 months Zillow Observed Rent Index, June 2026	$27,300	$21,720	+$5,580
State and local income tax Illinois 4.95% flat (Tax Foundation, 2026); Tennessee taxes no wages	$3,920	$0	+$3,920
Sales tax, including groceries TaxCloud 2026 city rates; TN Dept. of Revenue Notice 26-19	$2,560	$3,000	−$440
Kept per year in Nashville	+$9,060

Owning a $475,000 home in both places, per year
Line	Chicago	Nashville	Difference
State and local income tax Illinois 4.95% flat (Tax Foundation, 2026)	$3,920	$0	+$3,920
Property tax on a $475,000 home Cook County statutory calculation; Metro Nashville Trustee 2026 rate	$9,020	$3,340	+$5,680
Sales tax, including groceries TaxCloud 2026; TN Dept. of Revenue	$2,560	$3,000	−$440
Home insurance NerdWallet state averages, May 2026	$3,240	$4,220	−$980
Kept per year in Nashville	+$8,180

Sample, not a quote. Married couple filing jointly, $85,000 in wages, figures as of November 2026, rounded to $10. Buying each city's typical home instead (Nashville's is pricier than Chicago's) comes out −$900 a year once the mortgage is counted. The calculator shows that too: it prints the losers as well as the winners.

Step 3

What the lead email contains

You get the lead the moment a mover clicks submit: their answers, budget, timeline and result, by email. On a co-branded calculator, both professionals get it.

If they click “Start the conversation”, they choose how they’d like to hear from you (a call, a text, or both) and you get that too. Their consent is recorded with the exact wording they agreed to and when, with calls and texts kept separate. Contact them only in the ways they agreed to.

Political or personal-preference answers are never included, and never shared with anyone.

Sample

From: CityProof leads

Subject: New lead from your Nashville money calculator: moving from Chicago

Name: Sample Mover
Email: mover@example.com
Phone: (615) 555-0100
Wants to talk: Yes: clicked “Start the conversation”
Contact consent: Calls: yes · Texts: no · agreed Nov 12, 2026 at 3:41 pm, consent text v1
Moving from: Chicago
Timeline: 6 to 12 months
Household income: $70,000 to $110,000
Plans to: Rent first
Monthly housing budget: $2,200
Their result: Renting in Nashville, about +$9,000 a year vs Chicago
Guide: Moving to Nashville, emailed to the mover with your name on it

Sample lead email with fictional contact details. The result line uses the sample figures in the table above ($9,060, rounded to the nearest $500 for the mover).

And the mover

They get the guide, with your name on it

CityProof emails the mover the full, in-depth guide to your city, branded with your name, photo and brokerage (or NMLS number and lender, for loan officers) on every page, including a money chapter for their own origin and income. It’s the follow-up you would have had to write yourself.
