How to Plan Your Savings Goal
Whether you're saving for a house deposit, emergency fund, holiday or any other goal, the key variables are: target amount, timeline, starting balance, and the interest rate you can earn. Our savings calculator works out either how long it will take at your current savings rate, or what monthly contribution you need to hit your goal by a specific date.
The Emergency Fund Rule
Most financial advisors recommend having 3–6 months of living expenses in an easily accessible savings account. This emergency fund is your financial buffer against job loss, unexpected medical bills or major repairs. On a $4,000/month expense budget, your target emergency fund is $12,000–$24,000 — a useful concrete savings goal to start with.
High-Yield Savings Accounts
Online banks and challenger banks typically offer significantly higher interest rates than traditional brick-and-mortar banks. In the US, high-yield savings accounts (HYSAs) currently pay 4–5% APY versus 0.5% at big banks. In the UK, easy-access savings accounts at online banks offer 4–5% AER. The difference compounds significantly on larger balances over longer timeframes.
Frequently Asked Questions
How much should I save each month?
Financial advisors commonly recommend saving 20% of your net income (the 50/30/20 rule allocates 50% to needs, 30% to wants, 20% to savings and debt). For specific goals, work backwards: decide when you need the money and how much, then calculate the required monthly contribution using a savings calculator.
How long does it take to save $10,000?
At $500/month with no interest, saving $10,000 takes 20 months. With a 5% annual interest rate, it takes about 18–19 months. At $300/month, it takes about 31 months with interest. The actual time depends entirely on your monthly contribution and the interest rate you earn.
What is the best savings account interest rate?
Interest rates change frequently with central bank decisions. High-yield savings accounts (HYSAs) in the US typically offer 4–5% APY as of 2025, compared to 0.5% for traditional savings accounts. In the UK, easy-access accounts offer 4–5% AER. In Australia, at-call savings accounts offer 4–5.5%. Always shop around and compare rates.
Should I save or invest?
For short-term goals (under 3 years), save in cash — markets can fall significantly in the short term and you may need the money. For medium-term goals (3–7 years), consider a balanced approach with some low-risk investments. For long-term goals (7+ years), investing typically outperforms saving because time allows you to ride out market volatility.
What is compound interest on savings?
When you earn interest on a savings account, that interest is added to your balance. In the next period, you earn interest on the larger balance — interest on interest. This compounding effect accelerates growth over time. A $10,000 deposit at 5% with annual compounding grows to $16,289 in 10 years without any additional deposits.
