Boulder mortgage calculator
A median-priced Boulder, CO home at 6.75% over 30 years, with Colorado property tax of 0.51% and $3,100 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$6,625 a month, all in
Principal and interest are $5,567; escrow and PMI add the rest. Over the full term the loan costs $1,145,890 in interest. Discounted at 5%, buying here has a net present value of $-178,846 ($289,295 in today’s dollars).
Within Colorado, Boulder is the most expensive of the 6 Colorado markets covered here. Prices here run 2.06x those in Colorado Springs, the cheapest market listed, so a statewide average badly understates what a purchase costs on this side of the state.
Boulder carries a premium over the rest of Colorado: a median home here runs $953,750, about 75% above the state median of $545,000. The deposit moves with it, so the same 20% down is $190,750 rather than $109,000.
Prices here have run ahead of rents: the local price index sits at 1.75 against a rent index of 1.35. 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
Colorado medians come from editorial and are refreshed weekly. The Boulder 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.
