Wedding Compound Annual Growth Rate Calculator (15 Years)

Calculate compound annual growth over a period. This wedding version uses a 15-year planning term as its starting point.

In plain terms, this percentage is the steady yearly growth rate that would take the starting value to the ending value over 15 years, smoothing out any uneven growth along the way.

Formula

CAGR equals ending value divided by starting value, to the power of one over years, minus one.

How it works

CAGR smooths growth into a single yearly rate, even if actual yearly growth varied.

Worked example

Starting value $10,000, ending value $20,000, term 15 years. The ending value divided by the starting value is $20,000 divided by $10,000, which is 2. Using the page formula, the compound annual growth rate is 2 to the power of one over 15, minus one, which gives 4.73 percent a year. That is the calculator's own result for these defaults, and it is the same starting and ending values as every page in this group, because the term is the only input that changes: a longer term spreads the same doubling over more years, so the yearly rate falls as the term rises.

Who this term suits for a wedding: parents building a wedding fund over 15 years, where a steady rate under 5 percent a year is enough to double the fund, and yearly ups and downs are smoothed away.

FAQs

What does CAGR mean?
CAGR is the steady yearly growth rate that would take a starting value to an ending value.

Is this wedding calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Why is the 15-year rate only 4.73 percent for the same doubling?
Because 15 years of compounding spreads the doubling thin. Two to the power of one over 15, minus one, is 4.73 percent a year, so a modest steady rate is enough to double a wedding fund when the term is 15 years.

Does a 15-year wedding fund need checking every year?
Yes. CAGR is a smoothed average, so a fund can look steady at 4.73 percent while some years grow fast and others fall. A yearly check keeps the wedding budget on track and catches a bad year early.

What if the wedding budget grows to $30,000 over 15 years?
Then the rate is 3 to the power of one over 15, minus one, which is about 7.60 percent a year. A larger ending value over the same term always raises the yearly rate, so a bigger wedding needs either more saving or a stronger return.
