Is $100,000 a Good Salary in Charleston?

Short answer: workable, with less slack than you're picturing. Here's what that number leaves out.

Here's an unusual thing about Charleston: it costs about what the average American city costs. No premium to explain away, no bargain to talk yourself into.

So let's put real numbers on it.

Where the money actually goes

Start with the headline number and subtract reality. Single filer, standard deduction, 2026 brackets:

That last row is the one that matters and it's the one nobody shows you. Your $74,936 spends like $74,194 would somewhere average. The federal government scores every metro against a national average of 100, and Charleston scores 101.0. Charleston takes roughly $700 a year off you before you've bought anything, purely for the privilege of buying it there.

The part South Carolina takes

Nobody negotiates against state tax. Everybody pays it.

South Carolina takes about $4,244 of this salary, an effective rate of 4.2% once brackets and deductions shake out.

That's on top of federal. Together with FICA it's why your monthly deposit looks nothing like the annual figure you negotiated.

What changes if you file jointly

Everything above assumes a single filer, which is the common case for "is this salary any good" and the wrong one for plenty of readers. If $100,000 is a household's income and you file jointly, the federal picture changes a lot: the standard deduction doubles and every bracket widens, so federal tax falls from $13,170 to $7,640. That is $5,530 a year back in your pocket.

One caveat on that joint column, and it runs in your favour. We hold South Carolina tax at the single-filer figure, because state schedules for joint filers vary and we would rather understate the benefit than guess at it. Most states widen their brackets for joint filers too, so your real joint take-home is likely a little higher than the number above, not lower.

The average hides the important part

Charleston being 1% above average is a blended figure, and blending is exactly what you don't want here. Groceries and everyday goods run 4% below average. Housing runs 20% above it.

Which means the cost of living here is mostly the cost of being housed here. Everything else is close to ordinary.

Can you actually afford to live there?

A one-bedroom at Charleston's fair market rent runs $1,630 a month, $1,787 for a two-bedroom. Against take-home of $6,245 a month, the one-bedroom eats 26% of it.

That lands right on the 30% rule, the traditional line for affordable. It works, and it leaves $4,615 a month for everything else, which is enough but not generous.

Charleston hasn't always cost this much

Charleston has been on both sides of the national average. It spent 4 of the last 17 years above it, and it's above it now at 101.

That crossing is why Charleston gets described as both cheap and expensive depending on who you ask and when they last looked.

Most of that shift is recent: 2.8 points of it landed in the last five years.

What salary would actually feel like $100,000?

Reverse the question and it works in your favour: $101,000 here matches $100,000 in an average city.

The same salary is simply worth more here. Useful to know before anyone talks you into a lower number.

The verdict

It's solid. $100,000 converts to $74,194 of real spending power in Charleston, which puts you in decent shape without putting you in a penthouse.

Comfortable for one person. Workable for two. It starts asking questions once there are children involved.
