Goal based investing
Overview
Achieving a financial goal can seem daunting, but breaking it down into clear, manageable steps makes the process much simpler.
Whether you're saving for a home deposit, a dream wedding, or your child's education, a well-structured plan is key. In this guide, you'll learn how to set realistic financial goals, decide on your time horizon, account for inflation, and determine whether saving or investing is the best route for you.
1. Define your goal
The first and most important step is to clearly define what you are saving for. Be specific about both the amount you need and the purpose of the savings. Having a well-defined goal will help you stay focused and make it easier to create a realistic savings plan.
Key questions to consider:
  • What are you saving for?
  • How much do you need to reach your goal?
Examples:
  • Property deposit: - £30,000

    This is a common goal for first-time homebuyers. The average price of a property in the UK is around £300,000, so a 10% deposit typically amounts to approximately £30,000. Depending on where you live, this amount may vary, so consider adjusting based on the average house prices in your area.
  • Wedding: - £10,000

    The cost of a wedding can vary significantly, but the average cost in the UK is around £18,000 to £20,000. Many couples opt for smaller, more intimate ceremonies and aim to spend closer to £10,000.
  • School fees: - £120,000

    Private school fees can be substantial. On average, yearly fees for private schools in the UK range from £12,000 to £18,000 per year. Over several years of education, these costs can add up to £120,000 or more.
2. Set your time horizon
Once you've defined your goal, determine when you want to achieve it. The time horizon affects how much you need to save each month and whether it's feasible to save or invest to reach the target.
Example scenarios:
  • Short-term goal (1-3 years): - Saving for a holiday, car, or home improvements.
  • Medium-term goal (3-5 years): - Saving for a a property deposit.
  • Long-term goal (5+ years): - Goals like a child's education, retirement, or larger financial commitments.
3. Adjust for inflation
If your goal is long-term, it's essential to consider inflation, which reduces the purchasing power of money over time. For most long-term goals, adjusting for inflation is crucial to ensure your savings will meet future costs.
The inflation rate typically ranges from 2% to 3% per year, depending on the country and economic conditions. Failing to account for inflation could leave you short of your target, even if you meet your nominal savings goal.
Formula: To adjust an amount for the effects of inflation, use the following formula:
Future value = Present value × (1 + Inflation Rate)Number of years
Example:
You want to save £30,000 for a home deposit in 5 years, and you expect an average annual inflation rate of 2.5%. Using the formula:
Future value = £30,000 × (1 + 0.025)5
Future value = £30,000 × 1.1314 = £33,942.25
What does this mean?
Due to inflation, you'll need to save £33,942.25 to have the equivalent purchasing power of £30,000 today.
4. Decide whether to save or invest
Now that you know your goal and time horizon, decide whether you want to simply save or invest your money. The choice between saving and investing depends largely on your risk tolerance, the time horizon for the goal, and capacity for loss. While saving offers more security, investing typically yields better returns over time, as investments have the potential for higher growth, particularly over long-term periods.

Saving:
If your time horizon is short (under 5 years) or you want low risk, keeping your money in a high-yield savings account other savings product may be best.
  • Low risk: - No risk of losing money, but sujected to inflationary pressures.
  • Lower return: - Typical returns range from 3% to 5% annually.
Investing:
If you have a longer time horizon (5+ years) and can tolerate more risk, investing in stocks, bonds, or mutual funds could help you achieve higher returns.
  • Moderate to high risk: - You may experience market fluctuations, but investments generally grow over time.
  • Higher return: - Returns from a balanced investment portfolio can average 5% to 8% annually.
5. Run the numbers
Now that you know your goal, time horizon, and whether you're saving or investing, you can calculate how much to save each month.
Formula: The formua for calculating this is:
Monthly saving amount = Goal amount x r ( 1 + r )nt - 1
Where:
r = Annual interest/growth rate
n = Number of times interest is compounded per year
t = Time, in years
