Ending Value

Example

Investing $25,000 up front plus $50 per month for 20 years at an expected 7% annual return (with a 0.5% expense ratio) grows to approximately $112,072 — after $10,047 in combined sales charges and fund expenses over the life of the investment.

What is a Mutual Fund?

A mutual fund is an investment fund that pools money from many investors to purchase a diversified basket of assets such as stocks, bonds, or other securities. Investors own shares proportional to what they've contributed, and the fund's value is calculated daily through its net asset value (NAV).

Unlike a single stock, a mutual fund gives investors instant diversification and professional management, but it also comes with costs — an ongoing expense ratio, and sometimes a sales charge (load) paid when buying or selling shares — that reduce your net return over time.

How Is Mutual Fund Growth Calculated?

Each contribution (minus any front-end load) is added to the balance, which then compounds monthly at your expected return minus the fund's expense ratio. At redemption, any back-end load is deducted from the final balance to arrive at your net ending value.

Balance = (Balance + Net Contribution) × (1 + (Return − Expense Ratio) / 12)

Front-End Loads Reduce What You Actually Invest

A front-end load is charged the moment you buy shares. For example, a $20,000 investment with a 5% front-end load means a $1,000 charge, leaving only $19,000 actually invested and compounding on your behalf — the fee never has a chance to grow with the rest of your money.

Expense Ratios Compound Against You

Because the expense ratio is deducted every year, its cost compounds just like your returns do — a fund charging 1% instead of 0.2% doesn't just cost 0.8% once, it costs a growing dollar amount every single year, which can add up to a large share of your final balance over decades.

Back-End Loads Discourage Early Withdrawals

A back-end load (or contingent deferred sales charge) is taken when you sell shares, and it typically shrinks the longer you hold the fund — designed to discourage short-term trading in and out of the fund.

Example — Your Current Inputs

Investing $25,000 up front plus $50 per month for 20 years at an expected 7% annual return (with a 0.5% expense ratio) grows to approximately $112,072 — after $10,047 in combined sales charges and fund expenses over the life of the investment.

Additional Example — A No-Load Index Fund

Investing $5,000 up front plus $100 per month for 20 years in a no-load index fund with a 7% average return and a 0.05% expense ratio grows to roughly $56,000 — with less than $200 lost to fees over two decades, versus thousands of dollars lost with a higher-cost actively managed fund charging 1.5% or more.

About These Parameters

Initial Investment & Monthly Contribution
The lump sum you start with and the recurring amount you add each month. Both are reduced by any front-end load before they begin compounding.
Expected Annual Return & Expense Ratio
Return should reflect the fund's underlying asset mix — stock funds have historically returned more on average than bond funds, with more volatility. The expense ratio is subtracted from that return every year, so a higher expense ratio directly lowers your net growth.
Front-End Load & Back-End Load
These are one-time sales charges some funds apply when you buy or sell shares. Many no-load and index funds charge 0% for both, while some actively managed funds sold through a broker charge as much as 5%.

Frequently Asked Questions

What's the difference between a load and an expense ratio?

A load is a one-time sales charge paid when buying or selling shares. An expense ratio is an ongoing annual fee charged every year you hold the fund, regardless of whether you trade shares.

Are index funds always cheaper than actively managed funds?

Not always, but on average yes — passively managed index funds typically charge well under 0.5% since they simply track a market index, while actively managed funds charge more to pay for research and portfolio management, rarely exceeding 2% annually.

Is this projection guaranteed?

No — this is an estimate based on a constant assumed annual return, which real markets never deliver exactly. Actual returns vary year to year, and this calculator does not account for taxes on distributions or capital gains.
