How do I calculate future value from CAGR?

Future value = Starting value × (1 + CAGR)years. Enter all three in the CAGR Future Value Calculator — months and days extend the period as fractional years.

What CAGR should I use for projections?

Use historical CAGR from your holding if you expect similar conditions, or a conservative assumption below past performance. Past CAGR does not guarantee future results.

Can I find CAGR from two balances first?

Yes. Use the Standard CAGR Calculator or Exact Dates Calculator to derive the rate, then return here to forecast different time horizons.

What does time to double mean?

At your entered CAGR, it is how long until the starting investment would reach twice its original value, assuming the rate stays constant. Shown in years, months, and days in the results panel.

Does the chart show every year?

The growth table and bar chart list integer year steps from year 0 through the modeled horizon, with the final row reflecting the full period including partial years when applicable.

Future value from CAGR

When you already know (or assume) an annual growth rate, this tool compounds it over your chosen period. It is the forward direction of CAGR math — instead of solving for the rate between two values, you solve for the ending value.

Formula

t = years (fractional months and days included)

Worked example

$100 at 10% CAGR for 5 years:

Future value = 100 × (1.10)⁵ ≈ $161.05
Year-by-year growth in the table shows how each year’s gain builds on the prior balance.
At 10% CAGR, doubling takes about 7 years, 3 months.

CAGR vs compound interest

CAGR here is a single smooth annual rate. The Compound Interest Calculator models nominal rates with explicit compounding frequency and optional deposits — better when you know payment schedules or monthly contributions.

Examples and use cases

Real-world use cases

Retirement projection: Someone assumes 7% long-term CAGR on $50,000 over 20 years to estimate a rough nest-egg target.
College fund: Parents model $15,000 growing at 6% CAGR for 12 years before tuition starts.
Business valuation: A founder projects $200K revenue growing at 15% CAGR for 5 years in a pitch deck scenario.
