How to save for college or university: targets, monthly amounts and accounts

Saving for college or university comes down to three numbers: what the years of study are likely to cost when your child starts, how much of that you want to cover from savings, and the monthly amount that gets you there given what you have already saved and a realistic return. Starting early matters more than any other choice, because it gives contributions longer to grow. The college savings calculator works through those steps, and this guide explains each one, along with the accounts that can make the money go further. It is general information, not financial advice.

Estimating the future cost

Start with today's cost of a year of study: tuition alone, or tuition plus housing, food and books if you plan to help with living costs too. Then inflate it to the years your child will actually study. Education costs have often risen faster than general prices, so the calculator lets you set a separate cost-inflation rate rather than assuming ordinary inflation. With 25,000 a year today, 4% annual cost growth and a 4-year-old who starts at 18, the four years cost about 43,292, 45,024, 46,825 and 48,698: roughly 183,800 in total. Those are future amounts, so they look large; How inflation erodes savings, and how to measure it explains why today's money and tomorrow's are not directly comparable.

From cost to savings target

Next, subtract what you already have, grown to the start date. Money saved now earns returns for every year until it is needed, so 8,000 invested at 6% a year for 14 years grows to about 18,087. The calculator compounds that monthly at the equivalent of your annual rate. The gap between the projected cost and the grown savings is what new contributions need to fill: in this example about 165,750.

The monthly amount

The monthly contribution is the regular payment that, growing at the same return, reaches the gap by the first year of study. It is the standard future-value-of-an-annuity calculation used for any savings goal. In the example, closing the full gap takes about 640 a month for 14 years. Time is the big lever: begin at birth with the same 8,000 already saved, and the monthly figure drops to about 505, even though four more years of cost inflation raise the projected total to about 215,000. That is compounding at work, and Compound interest, explained with real numbers shows the mechanics. To test other return assumptions, the compound interest calculator gives year-by-year detail.

Saving a share, not everything

Few families save the entire cost in advance, and the calculator lets you choose a percentage. Many aim for a share, such as a third, and plan to cover the rest from income during the study years, grants, scholarships, the student's own work or loans. Saving one third in the example sets a target of about 61,280; the existing savings cover around 18,090, leaving about 43,190 to save, or roughly 167 a month. A smaller, steady contribution you keep up is worth more than an ambitious one you abandon. Weigh it against other goals, too: retirement saving and an emergency fund usually come first, because there are loans for study but not for retirement. The student loan calculator shows what borrowing the remainder might mean.

Tax-advantaged accounts

Several countries offer accounts that make education saving more efficient. These are country-specific and their rules change, so check the official sources before acting:

• United States: 529 plans. Investment growth is free of federal income tax when withdrawals pay for qualified education expenses, and many states add a deduction or credit for contributions. Withdrawals for other purposes can face tax and a penalty on the earnings.
• United Kingdom: Junior ISAs. A tax-free account for under-18s, with an annual limit that has been £9,000 in recent tax years. The money belongs to the child and becomes theirs at 18, to spend on anything.
• Canada: RESPs. Growth is tax-sheltered and the government adds the Canada Education Savings Grant, 20% of the first 2,500 dollars contributed each year (up to 500 dollars a year, with a lifetime maximum).

The calculator does not model any account's tax rules or grants. If you use one, a grant effectively raises your contributions and tax-free growth raises your net return, so the true monthly figure could be lower.

Risks and trade-offs

Every number here is an assumption. Investment returns are not guaranteed and can be negative over several years, which is why many plans shift money into lower-risk holdings as the start date approaches. Costs may rise faster or slower than you assume, your child may choose a cheaper or more expensive route, or not study at all. Revisit the plan once a year, update the inputs and adjust the contribution. Pair it with the inflation calculator to sanity-check your cost-growth assumption against history.
