FAQs

Does a lower expense ratio guarantee a higher return?

No. This calculator deliberately holds gross return constant to isolate cost drag. Actual fund performance, tracking difference and portfolio choices vary.

Does this include exit load or tax?

No. It compares recurring expense ratios only and excludes one-time charges, transaction costs and tax.
