It is good that you are concerned about a 0.01% (or 1 basis point) increase in expense ratio. Each such 1 bps increase can decrease your return. SEBI the regulator of Mutual Funds is doing a great job by making the AMCs reduce their expense ratios. Recently a reduction of upto 20bps was implemented.
Illustration: Each 1 bps means that your end up getting lesser in the long run. Lets say you invest Rs 1,00,000 lumpsum for 25 years. Returns are 15%. The corpus will end up at 32.92 lakhs but with a 1 bps additional expense the corpus will be 32.85 lakhs i.e. a drop of Rs 7000.
Imagine what will happen with an additional expense of 150 bps or 1.5%. That is what almost 90% investors are incurring when they do NOT invest through “Direct Plans”. They go through brokers and other apps and buy regular plans
which means, that their corpus reduces.
