This calculator shows the opportunity cost of wedding spending against putting the money toward a house deposit, including how that deposit could grow. You enter the wedding budget, and it shows what the same money would do as a deposit or invested, helping couples make a deliberate, informed choice.
This shows the opportunity cost only. A wedding is a valid and meaningful choice; the point is to decide the spend deliberately, knowing what the money could otherwise do. Returns are not guaranteed. Estimate only, not financial advice.
The calculator takes your wedding budget and shows it as a lump sum that could instead go toward a house deposit today, then grows it at your assumed return over the chosen period to show what it might be worth if invested. This is the opportunity cost, what the money could have become. It is not an argument against a wedding, just a clear view of the trade-off so the decision is a conscious one.
A $35,000 wedding budget, if instead invested at a 6% return for 10 years, could grow to around $62,700. As a deposit today it is $35,000 toward a home. Seeing both helps a couple decide how much of that to spend on the day and how much to keep for their future.
