Wedding Future Value Monthly Savings Calculator (30 Years)

Estimate the future value of regular monthly savings. This wedding version uses a 30-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 30 years. The monthly rate is 6 percent divided by 12, which is 0.5 percent a month, and the number of deposits is 30 times 12, which is 360 months. Using the page formula, the future value is $500 times one plus 0.005 to the power of 360, minus one, divided by 0.005, which gives $502,257.52. That is the calculator output for these defaults. The couple pays in $180,000 in total, so $322,257.52 of the future value is interest. Without any interest, reaching the same $502,257.52 would need $1,395.16 a month for 360 months.

Who this term suits for a wedding: nobody as an ordinary wedding plan, because a 30-year horizon is a whole working life; its use is as an illustration of how a small steady habit compounds, and as a warning that wedding prices will not stand still for 30 years.

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.

Why does the 30-year figure pass $500,000?
Because interest of $322,257.52 is nearly double the $180,000 deposited. In the final years the fund grows by far more each year from interest than from the $6,000 a year of deposits.

Can a $502,257.52 fund still pay for a wedding after 30 years of price rises?
Only if wedding prices rise more slowly than the fund grows. If wedding costs rise at 3 percent a year, a $50,000 wedding today would cost about $121,363.12 in 30 years, so the fund would still cover it, but the comparison depends on real price growth, which this page does not model.

What should a couple do if the money is needed early?
Use only what the plan allows without penalty, and rework the plan afterwards. Taking money out early removes both the deposit and all the future interest it would have earned, which hurts a long plan more than a short one.
