How accurate are SIP calculators in predicting investment returns?

SIP calculators are designed to provide estimates of potential investment returns based on certain assumptions, such as the expected rate of return on your investment. While these estimates can be helpful in guiding your investment decisions, they may not always be accurate as there are many factors that can affect investment returns, such as market volatility, economic conditions, and unforeseen events. It's important to use SIP calculators as a guide and not rely solely on their estimates when making investment decisions.
