Money is a long game.
Budgeting, investing, taxes, retirement and debt — every figure shown as a calculation, every assumption dated.
What we cover
Seven sections, from the first reserve to the retirement number — the whole beginner tree, in the order you will need it.

Budgeting
Household cash flow for beginners: the 50/30/20 baseline and where it breaks, zero-based budgeting, and the weeks-of-money diagnostic.
Browse →Calculators
Compound-interest and retirement calculators with dated inputs — the site's original tools, built on published index and rate data.
Browse →
Debt
Debt against investing: the rate math of paying a balance off versus putting the money to work, shown as a calculation.
Browse →
Getting Started
How to start investing with little money — the first sequence: settle the budget, size the reserve, make the first contribution.
Browse →
Investing
Broad-market index funds, what they cost per year, and the default allocation for a first portfolio — the math of putting money to work.
Browse →
Retirement
How much you need to retire, the accounts that hold the savings, and the withdrawal number — every figure with its dated assumption.
Browse →
Taxes
What the tax code does at each step — contribution, growth, withdrawal — and the limits and rates that carry dates.
