What Is an Investment Return Calculator?
An investment return calculator helps you calculate your investment returns, ROI (Return on Investment) and annualised return. This investment return calculator UK shows you how effectively your investments are performing.
How to Use the Investment Return Calculator
Enter your initial investment, final amount, years held and optionally any additional contributions. Click Calculate Return to see your total return, ROI and annualised return.
How Investment Returns Are Calculated
ROI = (Total Return ÷ Total Invested) × 100
Annualised Return = ((Final Amount ÷ Total Invested)^(1/years) − 1) × 100
Investment Return Example
Example: £10,000 invested, £15,000 final value, 5 years, £2,000 additional contributions
- Total invested: £10,000 + £2,000 = £12,000
- Total return: £15,000 − £12,000 = £3,000
- ROI: (£3,000 ÷ £12,000) × 100 = 25%
- Annualised return: ~4.56%
Understanding ROI
- ROI (Return on Investment): Measures the efficiency of your investment
- Positive ROI: Investment made a profit
- Negative ROI: Investment lost money
- ROI vs Annualised Return: ROI is total return, annualised is average per year
Return Types Explained
- Total Return: Absolute profit/loss in monetary terms
- ROI: Percentage return relative to amount invested
- Annualised Return: Average annual return (useful for comparing investments)
- Real Return: Return adjusted for inflation
Good Investment Returns
- Cash: 0.5-4% (low risk, low return)
- Bonds: 2-5% (moderate risk)
- Stocks (UK): 5-7% (moderate to high risk)
- Global Stocks: 7-10% (higher risk, higher return)
- Property: 4-8% (moderate risk)
Common Investment Return Mistakes
- Not including additional contributions — they affect total return
- Ignoring inflation — real return is lower than nominal return
- Comparing different time periods — use annualised returns for comparison
- Not including fees — fees reduce your returns
- Focusing only on returns — risk matters too
