Wedding Future Value Monthly Savings Calculator (10 Years)

Estimate the future value of regular monthly savings. This wedding version uses a 10-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 10 years. The monthly rate is 6 percent divided by 12, which is 0.5 percent a month, and the number of deposits is 10 times 12, which is 120 months. Using the page formula, the future value is $500 times one plus 0.005 to the power of 120, minus one, divided by 0.005, which gives $81,939.67. That is the calculator output for these defaults. The couple pays in $60,000 in total, so $21,939.67 of the future value is interest. Without any interest, reaching the same $81,939.67 would need $682.83 a month for 120 months.

Who this term suits for a wedding: a couple saving steadily for a wedding about a decade away, or parents starting a wedding fund for a child while there is still plenty of time for interest to build.

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 is the 10-year interest $21,939.67, more than four times the 5-year interest?
Because compounding accelerates: after 5 years the fund is already $34,885.02, and that larger balance earns interest for another 5 years. The second 5 years add about $47,054.65, far more than the first 5 years added.

Should a couple count on 6 percent every year for 10 years?
No. The 6 percent is only the entered assumption. Real returns vary year to year, and a lower average return would leave the same $500 deposit short of $81,939.67, so the figure should be treated as a planning estimate, not a promise.

What happens if the couple raises the deposit as income grows?
Raising the deposit raises the future value by more than the extra deposits alone, because each extra deposit also earns interest. Even an extra $100 a month from year 5 onward would add $6,000 of deposits plus several thousand more in interest.
