Wedding Retirement Corpus Calculator (15 Years)

Estimate a retirement corpus from monthly savings. This wedding version uses a 15-year planning term as its starting point.

The Future value result shows the total retirement fund your regular monthly savings could build up over 15 years at the rate you entered, combining every monthly payment with the growth earned on those payments.

Formula

Corpus uses the monthly rate and number of monthly savings to grow each saving with interest.

How it works

Starting earlier matters more than saving a little more later, because interest has longer to compound.

Worked example

Monthly saving $500, annual rate 7 percent, term 15 years. The monthly rate is 7 percent divided by 12, which is about 0.5833 percent a month, and the number of savings is 15 times 12, which is 180 months. Using the page formula, the future value is $500 times one plus the monthly rate to the power of 180, minus one, divided by the monthly rate, which gives $158,481.15. That is the calculator output for these defaults. The couple pays in $90,000 in total, so $68,481.15 of the corpus is interest. That is the same monthly saving and rate as on every page in this group; only the time input changes, and that alone produces the different corpus figures across the years.

Who this term suits for a wedding: parents who start saving while their child is young, so that by the wedding the fund can cover the celebration and still leave something toward the couple's later life.

FAQs

When should I start saving for retirement?
As early as possible. Time in the market allows compounding to do more of the work.

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 $68,481.15 on $90,000 of savings?
Because 180 monthly savings of $500 compound at 7 percent for up to 15 years. The earliest savings earn interest for the longest, so the total interest reaches $68,481.15 even though the couple paid in $90,000.

Is a 15-year wedding plan too long to trust?
A 15-year plan needs checking every year. Wedding costs, incomes and returns all change, so the couple should review the monthly saving each year rather than setting $500 once and forgetting it.

What if the couple saves only $400 a month?
The formula scales with the monthly saving, so $400 a month over 15 years at 7 percent gives $126,784.92, which is $31,696.23 less than the $158,481.15 from $500 a month.
