What Is the FV Function in Excel

What this does

FV projects a savings balance forward: a starting amount, a regular contribution and a growth rate become a figure at the end of the term. It is the compound-interest calculation with contributions built in, which is what separates it from a simple (1+r)^n. Enter contributions and the opening balance as negative, since they are money leaving your pocket, and the result comes back positive. Setting the type argument to 1 models deposits made at the start of each period, which grows slightly faster because each contribution earns for one extra period. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “what is the fv function in excel”. Start on a copy or a tiny sample, keep the affected formula visible, and compare the result with the tool above before you touch the real workbook. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. The point is a calculation you can defend to a CFO or an auditor, but the practical win is that someone else can open the file and understand what happened without asking you.

A worked example

Saving 500 a month for 20 years at 6 %, starting from 10,000: =FV(6%/12, 240, -500, -10000) returns about 264,000. Of that, 130,000 is contributions and the rest is growth. Depositing at the start of each month instead, =FV(6%/12, 240, -500, -10000, 1), adds roughly another 1,100. FV is the projection behind every savings and retirement plan, and it is the contributions argument that makes it more useful than raw compounding. If there is any chance you will reuse this, drop it into a small template tab right now: a labelled input area on the left and the formula beside it, checked once against the tool above. Next time the same question comes up, the answer is a single paste away instead of a rebuild from memory.

In Google Sheets

Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. Nothing on this page is behind a login: the tool runs entirely in your browser, the formula is shown in full with one-click copy, and the steps work the same on Windows and Mac. That is the whole promise here — the exact answer, a way to prove it on your own numbers, and just enough context to make it stick. The short version of “what is the fv function in excel”: the answer is at the top of this page, the tool proves it on your own numbers, and the sections above explain why it holds so the next variation does not stump you. Excel rewards people who reference cells instead of typing values and who keep inputs separate from formulas, because that is what makes a result you can audit months later. Build it once, deliberately, with the live tool as a check, and you convert a one-off lookup into a reusable skill — which is the whole point of learning the why and not just the what.

Common mistakes

• Entering contributions as positive, which returns a negative future value.
• Mixing an annual rate with monthly periods, which vastly overstates the result.
• Presenting a single projection as a forecast; vary the rate to show the range instead.
