## How it calculates

The House Hacking Calculator uses the following formulas to provide financial insights: 

1. Cash Flow (CF) = Total Rent Income (TRI) - Total Expenses (TE) 
2. ROI = (Net Profit / Total Investment) × 100 

Where: 
- Total Rent Income (TRI) is the total amount received from renting out portions of the house over a specified period, typically monthly. 
- Total Expenses (TE) include mortgage payments, property taxes, maintenance costs, insurance, and any other relevant expenses. 
- Net Profit is calculated as Cash Flow (CF) minus Total Investment, where Total Investment includes the initial costs of purchasing the property and any renovations. 
The calculations allow homeowners to understand their cash flow situation and estimate their return on investment over time, making it easier to decide on the viability of house hacking.

## Who should use this

Real estate investors evaluating rental income potential from a primary residence. First-time homebuyers considering shared living arrangements as a financial strategy. Property managers assessing the financial impact of renting out rooms in a multi-family dwelling. Landlords determining the profitability of converting a personal residence into rental units.

## Worked examples

Example 1: A homeowner rents out a basement apartment for $1,200 per month. The total monthly expenses, including mortgage, utilities, and maintenance, amount to $800. 

Total Rent Income (TRI) = $1,200 
Total Expenses (TE) = $800 
Cash Flow (CF) = TRI - TE = $1,200 - $800 = $400 

Example 2: An investor purchases a duplex for $300,000, spending an additional $20,000 on renovations. They rent one unit for $1,500 monthly and incur $1,200 in monthly expenses. 

Total Rent Income (TRI) = $1,500 
Total Expenses (TE) = $1,200 
Cash Flow (CF) = TRI - TE = $1,500 - $1,200 = $300 
Net Profit = Cash Flow (CF) × 12 months = $300 × 12 = $3,600 
Total Investment = Purchase Price + Renovations = $300,000 + $20,000 = $320,000 
ROI = (Net Profit / Total Investment) × 100 = ($3,600 / $320,000) × 100 = 1.125%.

## Limitations

The House Hacking Calculator has specific limitations that may affect its accuracy. It assumes that rental income remains consistent and does not account for vacancy periods. It also does not consider fluctuations in property value over time, which can impact overall ROI. Additionally, the calculator expects fixed expenses, while actual costs can vary due to unexpected repairs or changes in utility rates. Users should be aware that local market conditions may significantly influence rental rates and property appreciation, which are not factored into the basic calculations of this tool.
