How does a SIP calculator work in the UK?

A SIP calculator uses the formula: Future Value = P × [((1 + r)^n - 1) / r] × (1 + r), where P is monthly investment, r is monthly return rate, and n is number of months. It shows the future value of your regular investments and the total returns earned.

What is a good SIP return rate in the UK?

UK SIP returns depend on the investment vehicle. FTSE 100 historically returns 7-8% annually. Global equity funds return 8-10%. Conservative portfolios return 4-6%. A 7% annual return is a reasonable expectation for long-term UK SIP investors.

How much should I invest monthly in a SIP?

The general rule is 15-20% of your income. Start with £100-500 monthly and increase as income grows. A £500 monthly SIP at 7% over 20 years grows to £260,000. Use our SIP calculator to find the right amount for your goals.
