Wedding Return on Investment Calculator (20 Years)

Calculate return on investment as a percentage. This wedding version uses a 20-year planning term as its starting point.

The Return shown is the total gain on the amount invested over the whole period, expressed as a percentage of that invested amount, so a positive figure means the final value is above the amount invested and a negative figure means it is below it; it is not a yearly or annual rate.

Formula

Return equals final value minus invested amount, divided by invested amount, times 100.

How it works

A positive return means the final value is higher than the amount invested.

Worked example

Amount invested $10,000, final value $15,000, term 20 years. The gain is $15,000 minus $10,000, which is $5,000. Using the page formula, the return is $5,000 divided by $10,000, times 100, which gives 50.00%. That is the calculator's own result for these defaults, and it is the same on every page in this group because the term is not an input: only the amount invested and the final value are entered. Spread over 20 years, the same 50% total is equal to about 2.05% a year, because $10,000 compounded at 2.05% a year for 20 years reaches $15,000.

Who this term suits for a wedding: parents planning a wedding about 20 years ahead, or a wedding venue business judged over two decades of bookings.

FAQs

What is a good ROI?
There is no single good figure. Compare returns over the same period and with the same risk before deciding.

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 does the same 50% need only 2.05% a year over 20 years?
Because the gain is spread over 20 years. Compounding at 2.05% a year for 20 years turns $10,000 into $15,000, the same total as 8.45% a year over 5 years.

Can parents really plan a wedding 20 years ahead on one rate?
Only as a rough guide. Over 20 years wedding styles, prices, and the family's circumstances will change, so the plan must be reviewed regularly.

What happens if the fund earns less than 2.05% a year?
Then it will fall short of $15,000 after 20 years. Even a small yearly shortfall compounds into a large gap over two decades.
