📝 How to Forecast Your Wealth - Complete UK Guide
This wealth forecast calculator UK helps you project your financial future. By understanding how compound interest works with regular contributions, you can plan effectively for retirement, major purchases, and generational wealth.
💰 The Power of Compound Growth
Compound growth is the engine of wealth creation. Here's how it works:
- Start with £100,000 at 7% return over 20 years = £386,968 (without contributions)
- Add £500/month to the same investment = £778,544 after 20 years
- The additional £500/month invested (£120,000 total) grows to £391,576 – 3.3x your contributions
📊 UK Investment Returns (2026)
Typical returns for different asset classes:
- Cash savings: 3-5% (low risk, low return)
- UK Government Bonds (Gilts): 4-5% (low-medium risk)
- UK Equities (FTSE 100): 7-8% (medium risk)
- Global Equities: 8-10% (higher risk, higher return)
- Property: 4-6% + rental income (medium risk)
📈 Inflation and Real Returns
Inflation reduces the real value of your wealth:
- Nominal Return: 7% (what you see in investment statements)
- Inflation Rate: 2.5% (average UK inflation)
- Real Return: 7% - 2.5% = 4.5% (what your money actually grows in purchasing power)
- Over 20 years, 2.5% inflation reduces purchasing power by 38%

- Increase Savings Rate: Aim for 25-30% of income – each 1% adds thousands over decades
- Review Investments Annually: Rebalance portfolio, check fees
- Consider Higher Returns: Global equities historically outperform UK-only investments
- Start Early: A 25-year-old saving £500/month reaches £1.2M at 65; starting at 35 reduces to £566,000
