Wedding Savings Goal Monthly Deposit Calculator (35 Years)

Find the monthly deposit needed to reach a savings goal. This wedding version uses a 35-year planning term as its starting point.

This Monthly deposit is the regular amount to save every month for 420 months to reach the $50,000 goal, spreading the saving over a very long period so the monthly amount is small while interest grows steadily across the years.

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 35 years. The monthly rate is 5% divided by 12, which is about 0.4167% a month, and the number of deposits is 35 times 12, which is 420 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 420, minus one, which gives $44.01. That is the calculator output for these defaults. Over 420 months the couple pays in $18,484.41 in total, so $31,515.59 of the $50,000 goal comes from interest. Totals use the calculator's unrounded figure, so the rounded monthly amount times 420 can differ by a dollar or two.

Who this term suits for a wedding: a lifetime-horizon illustration rather than an ordinary wedding plan, where $44.01 a month looks tiny only because interest pays for nearly two-thirds of the goal, and no wedding should be planned 35 years ahead on one fixed rate and one fixed goal.

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.

How does $44.01 a month become $50,000 over 35 years?
420 deposits of $44.01 pay in $18,484.41, and interest adds $31,515.59 to reach $50,000. Nearly two-thirds of the goal comes from interest, which is why the monthly amount looks so small.

What does $50 a month reach over 35 years at 5%?
$50 a month for 420 months reaches $56,804.62, which is $6,804.62 more than the $50,000 goal, a buffer for price rises over 35 years.

Is 35 years too long to plan a wedding?
Yes, as a fixed plan. No wedding should be planned 35 years ahead on one rate and one goal. Use the 35-year figure only as an illustration of compounding, and set the real wedding budget much closer to the date.
