The financial education center

Everything here exists because a client asked the question. Plain language, both languages, and no email address required to read any of it.

The short answer

57 guides across seven clusters — retirement, 401(k) rollovers, business retirement plans, California taxes, investing basics, family money and careers in finance — plus 11 calculators and a glossary of every term they use. All of it free, none of it gated, and all of it written by the firm rather than syndicated from a vendor. Where a page uses a number, it cites where the number came from.

Retirement

When you can stop, how much is enough, Social Security timing, and how a California public pension changes the arithmetic.

401(k) rollovers

The four options when you change jobs, and the traps that make two of them expensive.

Business retirement plans

For owners: what the mandate requires, what a plan really costs, and which design survives your payroll.

Taxes

California-specific, because a high-tax state changes the answer.

Investing basics

First principles for first-generation investors. Nothing here requires you to believe anyone's forecast.

Family money

Written for households doing this without an inherited playbook. Much of this cluster exists in Spanish too.

Careers in finance

How this profession actually works, and how to get into it from here. These are the pages we would have wanted at nineteen.

Compare, side by side

The same question put two ways, with a table and a verdict — written by a firm that sells neither option.

All twenty-five comparisons

The hub: paying for advice, accounts, business owners, pensions.

Fee-only vs fee-based vs commission

Three ways an adviser is paid, where each shows in Form ADV, and why fee-only is not automatically cheaper.

Robo-adviser vs a human adviser

Where the algorithm is enough — written by the more expensive option.

401(k) vs 403(b) vs 457(b)

Same deferral limit, different rules, and the pairing that lets a California public employee save twice.

Index funds vs active management

What the evidence shows, with the sources.

Dollar-cost averaging vs lump sum

What the arithmetic favours, and why people do the other thing.

Is a financial adviser worth it?

Asked of an adviser, so it opens with the cost in dollars and lists the five cases where the answer is no.

AUM fee vs flat fee vs hourly

Three pricing models and the conflict each one creates — ours named first.

What advisers actually charge

Industry benchmarks by portfolio size, the three layers of cost, and where this firm sits — including the unflattering half.

Fiduciary vs best interest vs suitability

What each standard permits, when it attaches, and how to check any firm in two minutes.

Roll it over, leave it, or cash it out

Four options at a job change — including the case for leaving it alone, which nobody is paid to make.

Target-date fund vs a managed portfolio

When the fund is already the whole answer, and the four places it runs out.

529 plan vs Roth IRA for college

Which one, in what order, and the California rules that differ from the federal ones.

S-corp vs sole proprietor, for retirement

The S election saves payroll tax and shrinks your contribution base at the same time.

Social Security at 62 vs 67 vs 70

The percentage table, the survivor benefit that usually decides it, and the WEP/GPO repeal.

California

The state departs from federal law in more places than any other, and almost all of them cost money. This is the list.

Educational information only. Nothing on these pages is investment, legal or tax advice, none of it is personalised to your situation, and reading it does not create an advisory relationship. Investing involves risk, including possible loss of principal, and past performance does not predict future results.
