Wedding Compound Annual Growth Rate Calculator (25 Years)

Calculate compound annual growth over a period. This wedding version uses a 25-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 25 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 25 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 25, minus one, which gives 2.81 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: a silver-anniversary wedding celebration, or a fund built over 25 years, where doubling needs only a small steady yearly rate, and patience does most of the work.

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 25-year rate only 2.81 percent for a doubling?
Because 25 years of compounding is powerful. Two to the power of one over 25, minus one, is 2.81 percent a year, so even a rate close to inflation can double a wedding fund over a quarter of a century.

Should a 25-year wedding fund use today's prices at all?
Only as a starting point. A $20,000 wedding in 25 years will not cost what it costs today, so the fund target should be raised for price rises, and the 2.81 percent rate should be read as growth on top of saving, not as the whole plan.

How often should a 25-year wedding fund be recalculated?
Every few years at least. Returns, incomes and wedding expectations all shift over 25 years, so a fund left unchecked for a decade can drift far from the wedding it was meant to pay for.
