Wedding Future Value Monthly Savings Calculator (25 Years)

Estimate the future value of regular monthly savings. This wedding version uses a 25-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 25 years. The monthly rate is 6 percent divided by 12, which is 0.5 percent a month, and the number of deposits is 25 times 12, which is 300 months. Using the page formula, the future value is $500 times one plus 0.005 to the power of 300, minus one, divided by 0.005, which gives $346,496.98. That is the calculator output for these defaults. The couple pays in $150,000 in total, so $196,496.98 of the future value is interest. Without any interest, reaching the same $346,496.98 would need $1,154.99 a month for 300 months.

Who this term suits for a wedding: a very long wedding fund, such as a family saving across a generation, where the main lesson is how much of the final figure comes from interest rather than deposits.

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.

Is $500 a month really enough to reach $346,496.98?
At the page defaults, yes, but only because interest contributes $196,496.98, more than the $150,000 deposited. That depends entirely on earning 6 percent a year for 25 years, which is an assumption, not a promise.

What is the biggest risk in a 25-year wedding savings plan?
Stopping early. Most of the growth happens in the later years, when the balance is large, so stopping at year 15 would give only $145,409.36, less than half the 25-year figure, even though 60 percent of the deposits were already made.

Should the deposit rise as income grows over 25 years?
Yes, if income allows. A fixed $500 deposit loses buying power over 25 years as wedding prices rise, so raising the deposit with income keeps the fund in step with the real cost of the wedding.
