Wedding Return on Investment Calculator (35 Years)

Calculate return on investment as a percentage. This wedding version uses a 35-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 35 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 35 years, the same 50% total is equal to about 1.17% a year, because $10,000 compounded at 1.17% a year for 35 years reaches $15,000.

Who this term suits for a wedding: a multi-generational wedding fund, where the money may pass from parents to children before any wedding is paid for.

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 total matter more than the yearly rate at 35 years?
Because a 50% total over 35 years is only about 1.17% a year, which may not keep up with wedding price rises. The yearly rate, not the headline total, shows whether the fund is really growing.

Who keeps a 35-year wedding fund on track?
Whoever owns the fund must review it regularly, and the plan should survive changes in the family, since 35 years spans more than one generation of wedding plans.

Is 35 years too long to judge from one ROI figure?
Yes. A single 50% figure over 35 years hides every rise and fall in between, so it should never be the only reason to choose an investment.
