The basics

Finance 101

Overwhelmed and not sure where to start? These are the foundational levers of personal finance, explained in plain English. Each one is a short overview with a link to go deeper. Educational only, not financial advice.

Saving vs. investing

Saving keeps money safe and easy to reach; investing puts money to work over longer periods, with more ups and downs along the way. Knowing which job each one does, and over what time horizon, is the groundwork the rest of these topics build on.

How compound interest works

Cash flow: money in, money out

Cash flow is simply what comes in versus what goes out each month. Seeing that picture clearly, with a framework like 50/30/20 as one lens, makes every other decision easier to reason about.

Traditional IRA vs. Roth IRA

Both are retirement accounts with tax advantages; the main difference is when you get the tax break, now (Traditional) or later (Roth). Which one fits depends on your situation and your view of future tax rates.

High-yield savings (HYSA)

A high-yield savings account works like a regular savings account but typically pays more interest, which is why it is a common home for an emergency fund or short-term cash. Rates move up and down with the broader market.

High-yield savings

HSA vs. FSA

Both let you set aside pre-tax money for medical costs, but they work differently: an HSA (paired with a high-deductible plan) can roll over year to year and be invested, while an FSA is generally use-it-or-lose-it within the year. The fit depends on your health plan and spending.

401(k)s

A 401(k) is a workplace retirement account, often with an employer match. This walks through how contributions, the match, and the tax treatment work, so you can weigh what role it plays for you.

Index funds

An index fund holds a broad basket of investments designed to track a market index rather than trying to beat it. This explains what they are and how they differ from picking individual stocks.

Wills & trusts

Estate planning is about deciding, in advance, who receives what and who makes decisions if you cannot. Wills, beneficiaries, and trusts are the basic tools; this is a plain-English overview of each.

Lifestyle creep

Lifestyle creep is the tendency for spending to rise alongside income, so a 20% raise does not automatically mean 20% more saved. Understanding the pattern, and keeping an eye on your own savings rate, is a useful lens as your income grows.
