Columbia mortgage calculator
A median-priced Columbia, SC home at 6.75% over 30 years, with South Carolina property tax of 0.53% and $2,600 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$1,772 a month, all in
Principal and interest are $1,357; escrow and PMI add the rest. Over the full term the loan costs $279,339 in interest. Discounted at 5%, buying here has a net present value of $128,134 ($318,546 in today’s dollars).
Within South Carolina, Columbia is the cheapest of the 4 South Carolina markets covered here — Charleston runs about 2.00x these prices. Buyers priced out of the expensive end of the state often end up comparing exactly this pair.
Columbia is cheaper than South Carolina as a whole — $232,500 against a state median of $310,000, roughly 25% below. On a 20% deposit that is $15,500 less to find up front.
Rents here are high relative to prices — a rent index of 0.90 against a price index of 0.75. That combination favours buying sooner, because the payment you avoid is larger relative to the price you pay.

Where these numbers come from
South Carolina 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.
