Wedding Return on Investment Calculator (25 Years)

Calculate return on investment as a percentage. This wedding version uses a 25-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 25 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 25 years, the same 50% total is equal to about 1.64% a year, because $10,000 compounded at 1.64% a year for 25 years reaches $15,000.

Who this term suits for a wedding: a couple planning a silver-anniversary celebration, or a wedding fund held for a full generation before it is spent.

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 is the 25-year yearly rate only 1.64% for a 50% total?
Because the same $5,000 gain is spread over 25 years. Compounding at 1.64% a year for 25 years turns $10,000 into $15,000.

Should a 25-year wedding fund use today's prices at all?
Only as a starting point. Wedding prices in 25 years will be very different, so the fund should be re-priced against current wedding costs every few years.

How often should a 25-year wedding fund be recalculated?
At least every few years, and whenever income, wedding plans, or market returns change. A 25-year figure left alone is a guess, not a plan.
