EGI
Effective gross income
Effective gross income is gross potential income minus vacancy and credit loss. It is the money that realistically arrives in the account. Everything downstream — NOI, cap rate, DSCR — is built on EGI rather than on the rent roll, because nobody collects 100% of scheduled rent forever.
EGI = (scheduled rent + other income) − vacancy and credit loss
Worked example
$31,800 of scheduled rent plus $900 of other income is $32,700 of potential; a 5% allowance takes $1,635 off, leaving $31,065.
Every example in this glossary uses the same deal: a $265,000 duplex renting for $2,650 a month, bought with 25% down at 6.75% over 30 years, producing $19,310 of net operating income.
The mistake to avoid
Where this is calculated
The noi calculator computes this from your own numbers and shows the arithmetic expanded. Net operating income built line by line from gross scheduled rent, and why the mortgage never appears in it.
