A familiar situation
A monthly mutual-fund contribution plan depends on both deposits and uncertain returns. Compare several return assumptions rather than reading one projected ending balance as a promise.

How mutual fund is calculated
The projection compounds the opening balance monthly and treats each regular contribution as arriving at month end. It is a scenario with a steady return, not a forecast of market performance. Formula: Future value combines a compounded initial holding and a series of monthly investments. Use the displayed details to inspect the intermediate amounts and replace example assumptions with terms from your own quote or records.
Future value combines a compounded initial holding and a series of monthly investments.Starting with $5,000 and adding $200 monthly at 7% for 15 years gives about $77,000.
Assumptions & useful context
Constant monthly compounding is illustrative; returns vary and the estimate is before taxes, fees and inflation.
Financial projections use your assumptions. Actual returns, lender terms, fees and tax rules can differ; these results do not guarantee a future outcome.
Frequently asked questions
Mutual Fund Calculator: what does the result include?
Each contribution is added at the end of the month, so it earns interest only in later periods. Deposits at the beginning of a month would produce a slightly higher estimate.
Mutual Fund Calculator: which assumptions matter most?
No. It repeats one annual rate to illustrate compounding; actual returns vary and fees, taxes and inflation reduce spending power.
