BRRRR: How to Calculate Total Cash Invested?

[Alex Hohenstein]

Hello BP Community!

I'm working through some BRRRR scenarios on the BP calculator and I'm having trouble figuring out how the "Total Cash Invested" is calculated. I tried to duplicate the number on a spreadsheet and can't come up with the exact number. The total cash invested in this example ends up being $2532.70. Here's the formula I'm using to try to duplicate that number:

Purchase Price + Rehab + Rehab holding costs - Rent period cashflow - rent period loan paydown - refinance loan amount = total cash invested.

$100,000 + $25,000 + $2,392.70 - $2,377.56 - $586.14 - $121,500 = $2,929.00

I come up with $2929.00 when I use this formula, which is close but not exact. Is there another metric I'm not including or a metric that I shouldn't include? Any help or input is appreciated!!!
