Legal cost math, with the
citations attached.
Most legal cost calculators online return a number with no audit trail — no formula, no source, no work shown. This site is the opposite: every estimator uses the same primary source a licensed attorney would cite (state child-support guideline statutes, BLS Work-Life Tables, IRC §104 for settlement tax treatment, ABA Model Rule 1.5 plus state-specific contingency caps), and the math is open-source TypeScript with tests. Built for individuals navigating family law, personal injury, or settlement decisions — and for attorneys and paralegals who want the math worked transparently with citations.

Personal Injury
Lost Wages Calculator
Compute past + future lost-wages component of a personal injury claim: time off work × wage rate (past lost wages) + present value of future earning-capacity reduction × work-life expectancy (BLS Work-Life Tables) discounted at the IRS § 7872 applicable federal rate (AFR). Cited to BLS Work-Life Tables, IRC §104(a)(2) (settlement tax treatment), and the AAJ litigation-economics reference. Not legal advice.

Compute take-home settlement after attorney contingency fee + case costs + lien obligations + tax treatment. Standard 33⅓% contingency for pre-litigation, 40% post-filing, 45% post-appeal — but Florida cap at 33⅓% under Rule Regulating Florida Bar 4-1.5(f)(4)(B), California adjustment per Cal. Bus. & Prof. Code § 6146, and per-state limit overrides. Cited to ABA Model Rule 1.5 + state-specific contingency caps.

Concepts behind the legal cost math.
Child Support & Custody
Income Shares vs Percentage of Obligor Income vs Melson: the three child-support models, decoded
Child support varies more between states than between income levels within a state. The same family income produces radically different obligations under Income Shares vs Percentage of Obligor Income vs the Melson Formula. Here's why, with each state's primary statute cited.
Personal Injury
Lost wages in personal injury: why future earnings need present-value discounting
Future lost wages must be discounted to present value using BLS Work-Life Tables for work-life expectancy and the IRS applicable federal rate (AFR) as the discount rate. Without that discount, settlement demands overstate the claim. Here's the operator-grade math.
What makes this different
Three things every Bedrocka Tools site does that the lead-generation lawyer mills don't.
Open-source math
Every calculator's formula is published as TypeScript with Vitest tests in a public repo. Click "View source" in any math accordion to see the actual implementation. Most legal cost calculators hide their math behind a black-box engine; we publish ours.
Browse the math →Primary-source citations only
Every state child-support formula, contingency fee cap, and settlement tax treatment links to the original source — state guideline statute, ABA Model Rule, IRC section, BLS Work-Life Table. No "based on state law" hedging without a cite. The citation is the proof.
