Princeton mortgage calculator
A median-priced Princeton, NJ home at 6.75% over 30 years, with New Jersey property tax of 2.23% and $1,500 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$8,558 a month, all in
Principal and interest are $6,071; escrow and PMI add the rest. Over the full term the loan costs $1,249,516 in interest. Discounted at 5%, buying here has a net present value of $-309,863 ($169,759 in today’s dollars).
Within New Jersey, Princeton is the most expensive of the 5 New Jersey markets covered here. Prices here run 3.08x those in Newark, the cheapest market listed, so a statewide average badly understates what a purchase costs on this side of the state.
Princeton carries a premium over the rest of New Jersey: a median home here runs $1,040,000, about 100% above the state median of $520,000. The deposit moves with it, so the same 20% down is $208,000 rather than $104,000.
Prices here have run ahead of rents: the local price index sits at 2.00 against a rent index of 1.50. A market where buying costs rise faster than renting does is one where the rent-vs-buy answer leans later — you need a longer hold before ownership wins.

Where these numbers come from
New Jersey medians come from editorial and are refreshed weekly. The Princeton figures index those state medians to the local market, so they track the same feed rather than going stale. Insurance and the state income tax rate are editorial. Treat everything here as a planning estimate, not a quote.
