Eight rungs, all computed by the two engines on this page's build — nothing in this table is typed by hand. The non-US rungs use the same numerals as the US rungs, in the local currency.

The Maryland state line is a planning estimate and is labelled as such in the calculator — treat it as a planning number, not an exact withholding amount.

What $100,000 leaves in Baltimore, MD after a year of rent

Rent is the largest line most workers cannot move, so the take-home gap is only half the story. This site publishes rents for US metros only: there is no rent series for Adelaide, Australia, so this section deliberately covers one side instead of guessing the other.

Federal tax and FICA do not move between states; only the state line does. Maryland is highlighted, and the last column is the gap against Baltimore, MD.

Two engines, one salary each

Baltimore, MD: assets/js/tax-2026.js — 2026 federal brackets, the $16,100 standard deduction, FICA with the $184,500 Social Security cap, and the Maryland state model. Adelaide: au/calculator-au.js — Resident for tax purposes, low income tax offset applied, Medicare levy with the simplified low-income exemption. Both engines are the ones loaded by the site's own calculators, and both are checked at build time against tax-rules/2026.json.

In Baltimore, the federal government captures a significant share of income, supplemented by a 13,170 federal tax deduction. The state of Maryland adds its own layer, while FICA contributions fund social insurance programs. Conversely, the Australian system centers on federal income tax, which reaches a total of 20,788 after applying applicable offsets. The structure in Adelaide is consolidated, avoiding state-level income taxation for this salary level. Both systems rely on progressive brackets, yet they differ in how they categorize and distribute tax responsibilities between regional and central authorities.

The payroll deductions in Baltimore support the Social Security and Medicare systems through a 7,650 contribution, ensuring future benefits and current medical coverage. These funds are specifically earmarked for federal programs that workers access upon retirement or meeting eligibility criteria. In Adelaide, the deductions facilitate a broader range of social services, including the Medicare levy of 2,000 that maintains the national public health framework. While both regions utilize these funds to stabilize social welfare, the management of these resources remains strictly tied to the respective national mandates.

Comparing these two locations using identical numerals in local currencies creates a transparent framework for evaluating tax code efficiency. By holding the gross salary constant, users can identify exactly how much of their pay is retained after statutory obligations are met. This method avoids the distortion of fluctuating exchange rates, which shift independently of domestic tax rules. It is an honest comparison because it treats each jurisdiction as a sovereign system. However, this frame is purely fiscal and excludes the complex variables of local prices or lifestyle costs.

Baltimore, MD or Adelaide? What it means in practice

The data focuses on the payroll deductions that occur before a salary reaches a bank account. For Baltimore, the Maryland state line represents a 5.00% slice of the gross earnings. Meanwhile, Adelaide residents navigate a progressive federal schedule that accounts for national health funding. While both systems use graduated rates, the components within the paycheck differ significantly. We provide this breakdown to help workers visualize their statutory obligations without conflating local tax policy with broader economic purchasing power differences.

In practical terms, the Baltimore salary results in a take-home amount of 74,180. This final figure accounts for the standard federal and state liabilities that a typical worker in Maryland should anticipate. Because payroll laws are uniform across the state, this calculation provides a reliable baseline for annual financial planning. However, workers should remember that these totals are planning estimates. Actual take-home pay may fluctuate based on personal exemptions, contributions to private retirement accounts, or specific tax credits that this high-level view cannot fully capture.

Many people mistakenly assume that a higher gross-to-net ratio implies a superior quality of life in Adelaide, where the take-home is 77,212. This perception fails to account for the unique trade-offs inherent in each tax system. Relying solely on the net-to-gross percentage overlooks the specific government services funded by these taxes and the variance in personal out-of-pocket expenses. Comparing these two cities requires recognizing that tax structures are merely one piece of a complex puzzle that dictates how much capital a worker retains at the end of the year.
