Wedding Future Value Monthly Savings Calculator (15 Years)

Estimate the future value of regular monthly savings. This wedding version uses a 15-year planning term as its starting point.

This Future value is the total your regular monthly deposits grow to by the end of the term you entered, including the interest earned along the way, so it is larger than the total you paid in whenever the interest rate is above zero.

Formula

Future value uses the monthly rate and the number of monthly deposits to grow each deposit with interest.

How it works

Each monthly deposit earns interest from the month it is made until the end of the term.

Worked example

Monthly deposit $500, annual rate 6 percent, term 15 years. The monthly rate is 6 percent divided by 12, which is 0.5 percent a month, and the number of deposits is 15 times 12, which is 180 months. Using the page formula, the future value is $500 times one plus 0.005 to the power of 180, minus one, divided by 0.005, which gives $145,409.36. That is the calculator output for these defaults. The couple pays in $90,000 in total, so $55,409.36 of the future value is interest. Without any interest, reaching the same $145,409.36 would need $807.83 a month for 180 months.

Who this term suits for a wedding: parents saving for a child's wedding 15 years ahead, or a couple planning a large celebration with a long runway, where steady small deposits can grow into a serious fund.

FAQs

How does monthly saving grow?
Regular deposits grow because each deposit earns interest, and that interest then earns more interest.

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.

How can interest be $55,409.36 on $90,000 of deposits?
Because by year 15 the balance is large enough that interest itself becomes a major contributor. In the later years the fund earns more each year from interest than the $6,000 a year being deposited.

Is a 15-year wedding plan too long to trust?
A 15-year figure is useful as a direction, not a fixed promise. Wedding prices, incomes, and returns will all change, so the plan should be reviewed every year or two and the deposit adjusted rather than set once and forgotten.

What if the couple pauses deposits when plans are postponed?
Pausing deposits stops both the deposits and the growth on them. A pause in the middle years costs more than the same pause at the start, because the balance at that point is already large and would have earned interest on the paused money too.
