Free NNN & 1031 Calculators
The arithmetic every net lease decision runs on — free, fast, and shareable (inputs live in each page's URL). Built and checked by people who use them on real deals.
Two pages split the yield math. The cap rate calculator divides in-place NOI by price, or solves the price or income a target cap rate needs. The NOI calculator builds that income from rent, vacancy, reimbursements, and the expenses the landlord keeps.
In an exchange, the 1031 exchange deadline calculator turns the sale closing date into the 45-day identification deadline and the exchange deadline — day 180 or the tax return due date, whichever is earlier. The properties that can go on that written list are the 1031 exchange NNN properties for sale.
