How does the exact-dates CAGR calculator work?

It counts calendar days between your start and end dates, converts that span to years, then applies the CAGR formula. Use the CAGR Exact Dates Calculator when you know real purchase and valuation dates.

Why use calendar dates instead of years?

Investments rarely align with whole-year anniversaries. Exact dates capture partial years precisely — important for short holds, IPO lock-ups, or fund inception-to-date performance.

What if the end date is before the start date?

The calculator requires the end date to be after the start date. Swap the dates or correct the typo, then click Calculate again.

How many days per year are used?

The tool uses 365 calendar days per year when converting the date span to fractional years for the CAGR exponent — matching common finance calculator conventions.

Can I project future value from the CAGR result?

Yes. Note the CAGR % from this tool, then open the CAGR Future Value Calculator to model forward scenarios. For typed duration without dates, use the Standard CAGR Calculator.

Is weekend and holiday count included?

Yes. Calendar-day count includes every day between the two dates — weekends and holidays are part of the elapsed period.

Click Calculate — the tool counts calendar days, computes CAGR, and fills the growth table and chart.

Prefer typing years, months, and days instead of dates? Use the Standard CAGR Calculator. To forecast a future balance from a CAGR assumption, open the CAGR Future Value Calculator.

Why use exact dates?

Real investments rarely align with neat whole-year anniversaries. Funds report from inception date, stock lots have purchase dates, and business KPIs often span fiscal quarters. This calculator converts the actual day count between two dates into an annualized CAGR so you can compare holdings fairly.

Formula with calendar days

d = calendar days between dates

Worked example

$100 grows to $130 in exactly 365 calendar days:

Elapsed time = 1 year (365 days ÷ 365.25)
CAGR = (130 ÷ 100)¹ − 1 = 30%

The growth schedule shows year 0 and year 1 balances; doubling time reflects the 30% annualized rate.

Examples and use cases

Real-world use cases

Stock lot holding period: An investor bought shares on 15 March 2022 and sold on 10 August 2025 — exact dates yield a precise CAGR vs a rough “3 years” estimate.
Fund fact sheet: A financial analyst annualizes performance from fund inception date to the latest NAV for client reports.
Side project revenue: A SaaS founder measures CAGR from first paying customer date to year-end MRR milestone.

For total return without geometric annualization, see the ROI Calculator. For duration-based CAGR without a calendar picker, use the Standard CAGR Calculator.
