Columbia mortgage calculator
A median-priced Columbia, MD home at 6.75% over 30 years, with Maryland property tax of 1.05% and $1,500 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$4,117 a month, all in
Principal and interest are $3,270; escrow and PMI add the rest. Over the full term the loan costs $673,117 in interest. Discounted at 5%, buying here has a net present value of $50,056 ($395,123 in today’s dollars).
Within Maryland, Columbia is 2nd of the 5 Maryland markets covered here, between Annapolis at the top and Baltimore at the bottom of a 2.73x spread. A state-level median hides most of that.
Columbia carries a premium over the rest of Maryland: a median home here runs $560,250, about 35% above the state median of $415,000. The deposit moves with it, so the same 20% down is $112,050 rather than $83,000.
Prices here have run ahead of rents: the local price index sits at 1.35 against a rent index of 1.20. 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.
Monthly cost in Columbia vs comparable rent
Owning is stacked by component; renting is the local median asking rent.

Where these numbers come from
Maryland medians come from editorial and are refreshed weekly. The Columbia 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.
