Wedding Savings Goal Monthly Deposit Calculator (30 Years)

Find the monthly deposit needed to reach a savings goal. This wedding version uses a 30-year planning term as its starting point.

This Monthly deposit is the regular amount to save every month for 360 months to reach the $50,000 goal, spreading the saving over three decades so the monthly amount is modest and interest contributes a large share of the final goal.

Formula

Monthly deposit equals goal times monthly rate divided by one plus monthly rate to the power of months minus one.

How it works

Saving a fixed amount each month with interest reaches the goal faster than saving without interest.

Worked example

Goal amount $50,000, annual rate 5%, term 30 years. The monthly rate is 5% divided by 12, which is about 0.4167% a month, and the number of deposits is 30 times 12, which is 360 months. Using the page formula, the monthly deposit is $50,000 times the monthly rate divided by one plus the monthly rate to the power of 360, minus one, which gives $60.08. That is the calculator output for these defaults. Over 360 months the couple pays in $21,627.89 in total, so $28,372.11 of the $50,000 goal comes from interest. Totals use the calculator's unrounded figure, so the rounded monthly amount times 360 can differ by a dollar or two.

Who this term suits for a wedding: a very long horizon, such as parents saving from a child's birth, where $60.08 a month is a tiny habit and interest pays for more than half the wedding, but wedding prices and styles will change a lot over 30 years, so the fund needs regular review.

FAQs

How much should I save each month?
Divide the goal by the growth of regular deposits at the assumed rate to get the monthly amount.

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 $28,000 of interest?
Because 360 deposits of $60.08 pay in only $21,627.89, and interest adds $28,372.11 to reach $50,000. Over 30 years, interest pays for more than half the wedding.

What does $100 a month reach over 30 years at 5%?
$100 a month for 360 months reaches $83,225.86, which is $33,225.86 more than the $50,000 goal, enough to absorb large price rises over three decades.

Is a 30-year wedding plan the same as a retirement plan?
No. A wedding fund has a fixed date and a fixed purpose, while retirement saving runs for decades with no single spending date. A 30-year wedding plan should be reviewed as the wedding approaches and moved to safer, steadier saving.
