ADA Accommodation Cost Calculator
Reasonable accommodation cost and tax credit.
About this calculator
This calculator estimates the net out-of-pocket cost of a reasonable accommodation under the Americans with Disabilities Act (ADA) after applying the two federal tax incentives Congress created for accessibility spending: the Section 44 Disabled Access Credit, added to the tax code by the Omnibus Budget Reconciliation Act of 1990 the same year the ADA itself was signed, and the older Section 190 Barrier Removal Deduction. Section 44 is a tax CREDIT worth 50% of eligible costs between $250 and $10,250 (so a maximum credit of $5,000), but it is restricted to small businesses — employers with 30 or fewer employees OR $1,000,000 or less in annual revenue (an OR, not an AND, so a business can qualify on either test alone). Section 190 is a tax DEDUCTION of up to $15,000 per year, open to any business regardless of size, and this calculator converts it to an estimated tax SAVINGS at an assumed flat 21% corporate rate. A business cannot claim both benefits on the same dollar of expense, so Total Tax Benefit takes the larger of the two rather than summing them.
Net Cost After Tax Benefits is Accommodation Cost minus that larger benefit — it tracks Accommodation Cost almost dollar-for-dollar once the Section 44 credit and Section 190 deduction both cap out (above roughly $15,000 in this model), since neither benefit grows any further past its ceiling. The undue-hardship analysis flags a rough risk tier by comparing Accommodation Cost to Company Annual Revenue as a percentage — under 1% is scored Low, 1-5% Moderate, and over 5% High — as a starting point for the ADA's fact-specific undue-hardship defense, not a legal determination. Retention ROI compares Net Cost After Tax Benefits to the estimated cost of replacing the employee (Employee Annual Salary times the Replacement Cost Multiple you set), since most accommodations are dramatically cheaper than recruiting and training a replacement. Typical Accommodation Cost benchmarks this against a per-type figure — but only the Equipment/Technology figure ($500) reflects the Job Accommodation Network's own survey data, which has repeatedly found a median one-time cost around $500 (and a majority of accommodations costing nothing at all); the Workspace Modification ($2,500) and Schedule/Policy Change ($0) figures are illustrative planning estimates only and are not independently sourced to JAN or elsewhere, so don't read "far below $1,000" as true across every accommodation type.

How to Use This Calculator
- Enter Accommodation Cost — the total cost of the proposed modification or equipment.
- Set Company Annual Revenue and Employee Count — Section 44 tax credit requires 30 or fewer employees.
- Enter Employee Annual Salary and Replacement Cost Multiple (1–2x salary to replace the employee).
- Select Accommodation Type: equipment, workspace modification, or schedule adjustment.
- Review Net Cost After Tax Benefits — the Section 44 credit covers 50% of eligible costs ($250–$10,250).
- Compare Net Cost against Replacement Cost — most accommodations cost far less than hiring and training a replacement.

Frequently Asked Questions
Why doesn't Company Annual Revenue change Net Cost After Tax Benefits at the default values?
Company Annual Revenue only affects Net Cost After Tax Benefits through the Section 44 eligibility gate, which requires 30 or fewer employees OR revenue at or below $1,000,000 — at the default 50 employees and $2,000,000 revenue, the business already fails Section 44 on both tests, so nudging revenue up or down near $2,000,000 doesn't cross the $1,000,000 threshold and Net Cost After Tax Benefits stays anchored to the Section 190 deduction instead. Bringing revenue down to $1,000,000 or below (or employee count to 30 or fewer) would unlock the larger Section 44 credit and genuinely lower the net cost.
Can a business claim both the Section 44 credit and the Section 190 deduction on the same accommodation?
Not on the same dollar of expense in this model — Total Tax Benefit uses whichever of the two is larger, not their sum, matching standard guidance that these incentives apply to different portions of qualifying costs rather than stacking freely. Section 44 caps at a $5,000 credit (50% of costs from $250 to $10,250); Section 190 caps at a $15,000 deduction, worth about $3,150 in tax savings at the assumed 21% corporate rate — so Section 44 is the larger benefit whenever a small business qualifies for it.
How is the Undue Hardship Risk rating calculated?
It compares Accommodation Cost to Company Annual Revenue as a percentage: under 1% of revenue is rated Low, 1% to 5% is Moderate, and over 5% is High. This is a rough screening heuristic, not the actual ADA undue-hardship standard, which weighs the accommodation's cost against the employer's overall financial resources, the nature of its operations, and the impact on the business — factors this calculator does not model.
Does Replacement Cost Multiple affect Net Cost After Tax Benefits?
No — Replacement Cost Multiple only feeds Employee Replacement Cost and Retention ROI, the two outputs that frame the accommodation's cost against the alternative of losing and replacing the employee. It has no path into Net Cost After Tax Benefits, Section 44 Credit, or Section 190 Tax Savings, which depend only on Accommodation Cost, Company Annual Revenue, and Number of Employees.
Why does Net Cost After Tax Benefits track Accommodation Cost so closely for larger expenses?
Both tax incentives are capped — Section 44 tops out at a $5,000 credit and Section 190 at roughly $3,150 in tax savings (21% of its $15,000 deduction cap) — so once Accommodation Cost is well above about $15,000, Total Tax Benefit stops growing entirely. Every additional dollar of accommodation cost above that point becomes an additional dollar of Net Cost After Tax Benefits, since neither benefit can absorb any more of it.
