SOA vs CAS: Life/Health vs P&C Actuarial Paths (2026 Guide)

Pick SOA if you want to work in life insurance, health insurance, pension consulting, or retirement plans. Pick CAS if you want property and casualty insurance work (auto, homeowners, commercial lines, reinsurance). The first two preliminary exams (P and FM) are jointly administered by both societies, so you can defer the decision until after them. Both paths lead to fellowship designations (FSA for SOA, FCAS for CAS) that take 5-10 years to complete and earn $150,000-$300,000+ at fellowship level.

This is the credential pick that has the longest practical consequences: actuarial path takes 5-10 years through the exams, and switching mid-stream from one society to the other costs you exam credits. The good news is you do not have to decide on day one. The first two preliminary exams (P and FM) are jointly administered, so you can defer the decision until after them.

I passed the SOA exams. Most of my career observations below come from working alongside FSAs and FCASs on insurance and pension matters. For the family-to-job mapping view, see the Finance Credentials Map.

What Each Society Actually Does

SOA (Society of Actuaries)

Life insurance pricing, reserving, valuation, asset-liability management. Health insurance underwriting, pricing, predictive modeling, Medicare/Medicaid analytics. Pension funding, plan design, retirement consulting, post-employment benefits.

Day-to-day work for an SOA-track actuary might look like:

  • Pricing a new life insurance product (estimating mortality, lapse rates, expenses, then setting premiums)
  • Computing reserves for an annuity block under statutory accounting
  • Valuing a defined-benefit pension liability under FAS 87 (now ASC 715)
  • Building a stochastic asset-liability model for an insurance company's investment portfolio
  • Running a long-term care insurance experience study

CAS (Casualty Actuarial Society)

Property and casualty insurance pricing (ratemaking), reserving, predictive modeling, catastrophe modeling, reinsurance analytics.

Day-to-day work for a CAS-track actuary might look like:

  • Building a generalized linear model (GLM) for auto insurance pricing by territory, age, vehicle class
  • Computing loss reserves using chain-ladder, Bornhuetter-Ferguson, or stochastic methods
  • Analyzing catastrophe model output for hurricane exposure in Florida
  • Pricing a reinsurance treaty for workers' compensation
  • Working on a homeowners' rate filing for a state insurance department

The Joint Preliminary Exams (P and FM)

The first two exams are the same for both societies, so candidates can start without picking a side.

  • Exam P (Probability): 30 multiple-choice questions over 3 hours. Calculus-based probability, distributions, joint distributions, conditional probability, expectation. Heavy on integration. Exam P practice questions are 73.9% pure-numeric multiple choice on FreeFellow.
  • Exam FM (Financial Mathematics): 30 multiple-choice questions over 2.5 hours. Time value of money, annuities, loans, bonds, swaps, asset-liability matching. Exam FM practice questions are 85.6% pure-numeric, the highest of any credential in our bank.

Most candidates take P first. Many pass FM first if they prefer financial mathematics to probability theory. The order does not matter; both must be passed regardless of which society you choose.

Where the Paths Diverge

After P and FM, the paths split.

SOA path (after FM)

  • FAM (Fundamentals of Actuarial Mathematics): Short-term and long-term models, parametric estimation, pricing. 71.4% pure-numeric. Practice FAM.
  • SRM (Statistics for Risk Modeling): Regression, GLMs, time series, decision trees, unsupervised learning. 16.5% pure-numeric (lower because of the prose-shaped statistical-method choices). Practice SRM.
  • PA (Predictive Analytics): Project-based exam in R or Python. Not in our question bank format.
  • ATPA (Advanced Topics in Predictive Analytics): Project-based, R or Python.
  • ALTAM (Advanced Long-Term Actuarial Mathematics): Multi-state survival models, pension funding, long-term insurance pricing. Mostly written-answer. Practice ALTAM.
  • ASTAM (Advanced Short-Term Actuarial Mathematics): Loss models, credibility, simulation. Mostly written-answer. Practice ASTAM.

After ASA designation, candidates pick a specialty track for FSA modules:

  • ILA (Individual Life and Annuities)
  • GHC (Group Health Care)
  • RET (Retirement Benefits)
  • GFI (General Financial Insurance)
  • PA (Predictive Analytics)
  • QFI (Quantitative Finance and Investment)

Each FSA track has 2-3 modules and a Fellowship Admissions Course (FAC). Total time to FSA: 5-10 years.

CAS path (after FM)

  • MAS-I (Modern Actuarial Statistics I): Probability models, frequency and severity distributions, simulation. 16.5% pure-numeric on FreeFellow. Practice MAS-I.
  • MAS-II (Modern Actuarial Statistics II): Credibility theory, linear mixed models, statistical learning, time series. 0.2% pure-numeric (CAS uses interval-bucket choice format; real difficulty is closer to SRM). Practice MAS-II.
  • Exam 5 (Basic Techniques): Ratemaking + reserving. Written-answer.
  • Exam 6 (Regulation and Financial Reporting): NAIC regulation, US GAAP, statutory accounting. Written-answer.
  • Exam 7 (Estimation of Policy Liabilities, Insurance Company Valuation, Enterprise Risk Management): Written-answer.
  • Exam 8 (Advanced Ratemaking): Written-answer.
  • Exam 9 (Financial Risk and Rate of Return): Written-answer.

After Exam 6 + Online Course on Risk Management, candidates achieve ACAS designation. After Exams 7-9 and the COP modules, FCAS designation. Total time to FCAS: 6-10 years.

Comp and Career Trajectory

Entry-level (0-2 exams passed): Both paths start around $60,000-$80,000 depending on geography and company. Sign-on bonuses for each passed exam are common ($1,000-$3,000 per preliminary).

ASA / ACAS (3-7 exams passed): Both paths roughly $90,000-$140,000. Per-exam pay increase of $5,000-$10,000 is the norm at most large employers.

FSA / FCAS (full credential): Both paths roughly $150,000-$300,000 base + bonus. Senior FSAs in pricing at consulting firms and senior FCASs in pricing at large P&C carriers can run higher.

Job security: Among the highest of any finance career path. The credentialing barrier creates a stable supply-demand imbalance. FSAs and FCASs are not laid off in volume during downturns the way investment-banking or asset-management staff are.

CAS-credentialed actuaries earn a small premium over SOA-credentialed actuaries on average, especially at the FCAS level. The reason is structural: there are fewer FCASs (smaller exam pipeline, P&C industry is smaller than life/health combined) so the supply-side scarcity bumps comp.

How to Decide

Three decision frames that work:

1. What industry do you want to be in?

If you want to work in life insurance, health insurance, retirement consulting, or pension departments at large employers, SOA. If you want to work in auto/home/commercial insurance, reinsurance, or P&C consulting, CAS. The industries are operationally distinct: a life insurance pricing actuary and a homeowners insurance pricing actuary do very different work despite the shared credentialing infrastructure.

2. What kind of math do you prefer?

SOA-track work is heavier on multi-decade discount-rate forecasting, mortality and morbidity modeling, asset-liability matching. CAS-track work is heavier on frequency-severity modeling, GLMs for pricing, loss reserving, catastrophe modeling. SOA work has longer time horizons and more interaction with investments and capital markets. CAS work has shorter time horizons and more interaction with claims data and rate regulation.

3. Where can you find an entry-level job?

Geographic and employer concentration matters. SOA roles cluster in the Northeast (insurance hubs Hartford, NY, Boston), Midwest (Des Moines, Columbus, Chicago), and California. CAS roles cluster around the Midwest (Chicago, Bloomington, Columbus), Northeast (Hartford, NY), and Southeast (Atlanta). If you have a strong geographic constraint, look at which credential matches the employers in your target region.

For many candidates, the answer is to just pick one and start. Both paths are good. The cost of indecision is more expensive than the cost of picking the slightly-wrong one.

Switching Mid-Stream

If you complete the joint exams (P + FM) on one society's track and decide to switch, you carry both exams over to the other. No re-take.

If you complete SOA exams beyond FM (FAM, SRM, etc.) and switch to CAS, those exams do not directly transfer. CAS may grant partial credit (varies by exam) but you will likely need to take MAS-I, MAS-II, and Exams 5-9 from scratch.

The practical takeaway: do not switch lightly after exam 3+. The sunk-cost of accumulated exam pass credits is real.

Frequently Asked Questions

Q: Which is harder, SOA or CAS?

They are comparable in difficulty. Both have pass rates in the 30-45% range for preliminary exams. Both demand 200-400 hours per exam at fellowship level. CAS exams (5-9) tend to be perceived as harder because they are all written-answer with significant essay-style components; SOA exams have a mix of multiple-choice and written.

Q: Can I work as an actuary without finishing all the exams?

Yes. Most actuarial roles start before any exams are passed (some require P + FM by hire, some by year-1 anniversary). You progress through exams while working. The credential is the long-term signal; the day job starts much earlier.

Q: Do I need a math degree to be an actuary?

No. The exams test what they test directly. A math degree helps with the early preliminary exams (P, FM, FAM) because the calculus and probability are familiar. But the credentialing path is the exams themselves, not the degree. FSAs and FCASs come from English, computer science, economics, and engineering backgrounds.

Q: Can I do both SOA and CAS?

Technically yes; practically no. Once you commit beyond FM, you have selected a track. People who hold both designations are rare and usually picked them up over decades.

Q: How does actuarial credentialing compare to CFA in difficulty?

Actuarial is longer (5-10 years to Fellow vs 2-4 years to CFA charter), has lower per-exam pass rates (30-45% vs 40-55% for CFA), and demands more sustained quantitative depth. CFA is broader. Actuarial is deeper in a narrower domain. The credentials signal different things to different industries.

Q: Does the SOA or CAS exam process change in the next few years?

Both societies update curriculum and exam structure periodically. SOA's most recent overhaul (2018) introduced FAM, SRM, ATPA, ALTAM, ASTAM. CAS adjusts MAS-I and MAS-II content regularly. Check the current syllabus on soa.org and casact.org before committing to a study plan; relying on materials older than 2 years is risky.
