How to Use the Aiken, SC Multifamily Tax Calculator (Step-by-Step)
What this calculator does and why it matters
This calculator helps multifamily investors, brokers, and property managers quickly estimate property taxes and how taxes fit into a property’s cash flow picture. Rather than hardcoding local assumptions, the tool lets you enter the assessment ratio and millage (mills per $1,000) used by your municipality so you can reflect Aiken County or a specific town inside the county. The output includes assessed value, annual property tax, effective tax rate relative to market value, and a visual breakdown of major expense categories using Plotly.js.
Inputs you provide (and why they matter)
Market Value
Enter the market value or purchase price of the multifamily asset. This is the basis for assessment calculations.
Assessment Ratio (%)
Counties and states use assessment ratios to convert market value to assessed value. The calculator accepts a user-supplied ratio so you can mirror local rules in Aiken. (If you don’t know the ratio, contact the county assessor or your broker.)
Millage (mills per $1,000)
Millage (often shown as “mills”) is the local tax rate charged per $1,000 of assessed value. Enter the local combined rate (county + city + school + special districts) as mills (e.g., 200 means $200 per $1,000 assessed value).
Income and Operating Inputs
Provide gross annual rental income, an expected vacancy rate, annual operating expenses, annual debt service (mortgage payments), and depreciation (if you track it for tax planning). These let the calculator estimate effective gross income, NOI before tax, and post-tax cash flow.
What the calculator outputs and how to interpret them
- Assessed Value: Market value × assessment ratio. This is what the municipality will tax.
- Annual Property Tax: Assessed value × (mills / 1000). This is the property tax bill estimate.
- Effective Tax Rate (%): Property tax as a percentage of market value—useful to compare tax burden across properties.
- NOI Before Tax and After-Tax Cash Flow: Shows how much tax reduces operating income and what remains for investors after debt service.
- Visual Breakdown (Plotly.js): A responsive pie chart displays the relative size of property tax, operating expenses, vacancy loss, debt service, and investor cash flow. This is helpful for presentations and quick analysis.
Step-by-step usage in WordPress (embed & sizing tips)
- Open your page or post in the WordPress editor. Use the Classic editor’s “Custom HTML” block or Gutenberg’s “Custom HTML” block. If you prefer a plugin, any “Insert HTML” plugin or code snippet plugin works.
- Copy the single-file HTML (tool) into the Custom HTML block. The HTML file is a self-contained document (HTML, CSS, JS + Plotly CDN). If pasting into some builders that strip
<html>/<head>, place only the inner content (from the calculator container<div id="aiken-calculator">...and the necessary<script>tags). - Sizing: The tool uses
max-width: 720pxand responsive styling so it will fit comfortably between two sidebars on most WordPress themes. If your theme content area is narrower, the calculator will shrink to fit. If your content area is wider and you want it narrower, changemax-widthin the embedded CSS to your desired pixel width (e.g.,640px). - Publish and test: Click Calculate to verify the chart renders and inputs behave as expected. Use different millage and assessment values to reflect different municipalities in Aiken County.
