How to Save Money: A Practical Guide (and When to Start Investing)

Pay yourself first

The usual reason saving fails is that it is whatever is left at the end of the month, and nothing is left. Reverse the order: on the day you are paid, move a fixed amount to a separate account and live on the rest. Automate it so no decision is needed.

A simple budget: 50/30/20

The rule of thumb comes from Elizabeth Warren and Amelia Warren Tyagi's book "All Your Worth". It is a starting point: if housing is 60% of your income, adjust it and keep the habit.

• 50% needs: housing, food, transport, minimum debt payments.
• 30% wants: everything optional.
• 20% savings and extra debt payments.

The emergency fund

An emergency fund covers job loss, repairs or medical bills without selling investments or borrowing. A common target is three to six months of essential expenses. Keep it in a savings account at an FDIC-insured bank, where deposits are insured up to $250,000 per depositor, per bank, per ownership category (FDIC). See the FDIC deposit insurance page.

Inflation: why cash is not free of risk

If prices rise 3% a year and your account pays 1%, your money buys less every year. Over decades the difference is large. Savings accounts and short-term government securities are for safety and short goals; for long goals, many people also invest in assets that have historically grown faster than inflation, accepting that they can fall in the short term.

Test how interest builds up with the compound interest calculator, including an inflation setting.

Pay debt or save?

• Debt with a high rate (credit cards): usually pay it first.
• Debt with a low rate (some mortgages, student loans): you may balance repaying with saving and investing.
• Always keep a small emergency buffer so a surprise does not push you into new debt.

When to move from saving to investing

When you have an emergency fund, no expensive debt, and a goal at least five years away. Then read how to start investing. If financial independence is the goal, the financial independence calculator shows how savings rate and time are linked.

Habits that work

• Track spending for one month to see the real numbers.
• Cancel subscriptions you do not use.
• Raise your savings rate whenever your pay rises.
• Keep savings in a different bank from the one you spend from.
