How to calculate your savings growth
Use our savings calculator to project the growth and future value of your savings or investment over time. It uses the compound interest formula, giving options for daily, weekly, monthly, quarterly, half-yearly and yearly compounding.
If you want to know the compound interest for your savings account or investment, you should be able to find it out by speaking to your bank or financial institution. It's also worth noting that our savings calculator also allows you to enter negative interest rates, should you wish to.
What is the effective annual rate?
The effective annual rate (also known as the APY or AER) is the rate that actually gets paid after all of the compounding. When compounding of interest takes place, the effective annual rate becomes higher than the nominal interest rate. The more times the interest is compounded within the year, the higher the effective annual rate will be.
Why does a 5% APY yield less than a 5% nominal interest rate?
If you're comparing a 5% APY/AER with a nominal interest rate, it's important to recognize that an APY incorporates the effects of compounding interest within the year, while a nominal rate does not.
Nominal Rate compounded monthly: If you have a 5% per year nominal rate compounded monthly, this effectively becomes 5.12% APY due to the addition of interest on top of interest earned in previous months.
APY (already compounded): Conversely, if you start with a 5% APY, the equivalent nominal rate would actually be around 4.89%.
You're therefore comparing a 4.89% nominal rate (5% APY) with a 5% nominal rate (5.12% APY). So, you'll want to check if your 5% quoted rate is a nominal rate, rather than a 5% APY/AER.
What is the best way to save?
Whether you've got a specific savings goal in mind, from a new car, dream holiday, first home or just securing a comfortable retirement, it can be tricky to work out where to put your money to enhance your savings growth.
Exploring your options
Savings Accounts: A staple for most individuals, savings accounts offer you a secure place to store your funds, though interest rates are normally quite low.
Stock Market Investments: If you're seeking higher returns and are willing to endure market volatility, the stock market can be a rewarding place.
Tax-Advantaged Accounts: In the US, IRAs provide tax advantages for retirement savings. In the UK, ISAs offer a tax-free way to save and invest.
Peer-to-Peer Lending: An alternative investment with potentially higher returns than traditional savings, albeit with increased risk.
Risk tolerance
Before you dive in, it's always advisable to consider and assess your personal risk tolerance. Diversification — spreading your investments across various channels — can help mitigate risk and maximize returns.
Seeking professional advice
For personalized advice, you may wish to consult a qualified, independent financial advisor. An advisor can tailor investment strategies based upon your personal circumstances, risk tolerance and financial goals.
Financial Independence, Retire Early (FIRE)
FIRE (Financial Independence, Retire Early) is a lifestyle movement that looks to adopt strategies of frugality, extreme saving and investment in order to achieve financial independence at an early retirement.
If you're interested in the idea of retiring early, our savings calculator can help you work out forecasts on how to achieve the goals you want to hit.
