About Us

Last updated: November 4, 2025

We’re BigTechies—the team behind Expense Ratio Calculator. We created this tool so investors can see the real, long-term cost of fund fees before they commit money. A small percentage fee can add up over decades. Our calculator makes that impact obvious.

What the calculator does

Model your initial investment and optional yearly contributions
Set an expected annual return and the fund’s expense ratio
See the future value (after fees) and the total fees deducted
Switch among popular currencies (PKR, USD, EUR, GBP, INR, AED, SAR, CAD, AUD)
Read concise How it works, FAQs, and practical tips

Our principles

Accuracy, then clarity. We show the fee drag with plain language and transparent assumptions.
Privacy by default. No account is required just to run numbers.
Speed & usability. Clean UI, mobile-friendly layout, and sensible defaults.
Accessibility. Keyboard-friendly inputs, readable typography, and clear focus states.

Assumptions

By default, returns are compounded annually; the expense ratio is applied after growth; and yearly contributions are added at the end of each year. Real-world performance varies and other costs (brokerage, taxes, tracking difference) aren’t included unless noted.
