Emergency Savings Goal Monthly Deposit Calculator (10 Years)

Find the monthly deposit needed to reach a savings goal. This emergency version uses a 10-year planning term as its starting point.

This Monthly deposit figure is the regular amount to save each month so that, together with interest at the entered annual rate, the monthly deposits reach the goal amount by the end of the 10 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

A household wants a $50,000 emergency fund in 10 years, at 5% a year. The monthly rate is 5% divided by 12, which is 0.0041667, and there are 120 monthly deposits. Using the page formula, the monthly deposit is $50,000 times 0.0041667, divided by 1.0041667 to the power of 120 minus 1, which is $321.99 a month. Over 120 deposits the household pays in $38,639.31, and interest adds $11,360.69, which is 22.7% of the goal.

Doubling the term more than halves the monthly deposit, from $735.23 to $321.99, because interest now has ten years to work and the saver makes twice as many deposits. For an emergency fund this is a steadier pace: a family can build the same $50,000 safety net without squeezing every month, but the fund must still be topped back up whenever it is used, or the ten-year plan quietly becomes a plan with a hole in it.

Who this term suits for an emergency saver: a two-income family with a mortgage, building a fund that covers a long illness or a period without work, while still paying the mortgage and school costs from the monthly budget.

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 emergency 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 doubling the term more than halve the monthly deposit?
Because the saver makes 120 deposits instead of 60, and each early deposit earns interest for up to ten years. The $11,360.69 of interest does part of the work that the saver had to do alone over five years.

Is $321.99 a month enough if a job loss lasts a year?
That depends on monthly essential bills, not on the $50,000 headline. Divide $50,000 by monthly essentials: if essentials are $4,000 a month, the fund covers about twelve months; if they are $5,000, it covers ten. Set the goal from the bills, not from a round number.

What happens if the fund is used in year 4?
The plan restarts from whatever is left. After a $10,000 medical bill, for example, the remaining fund is $40,000, and the monthly deposit must rise, or the ten-year finish date must move, to reach $50,000 again.
