Emergency Future Value Monthly Savings Calculator (20 Years)

Estimate the future value of regular monthly savings. This emergency version uses a 20-year planning term as its starting point.

The future value is the total amount your regular monthly deposits are worth at the end of the 20-year term, including both the money paid in and the interest those deposits have earned.

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

A household saves $500 every month for 20 years at 6% a year for emergencies. The monthly rate is 6% divided by 12, which is 0.005, and there are 240 monthly deposits. Using the page formula, the future value is $500 times ((1.005 to the power of 240 minus 1) divided by 0.005), which is $231,020.45. The household paid in $120,000.00, so interest added $111,020.45, which is 48.1% of the future value. After 20 years interest is nearly as large as everything paid in, and the fund passes $200,000. For emergency planning this is a long-career cushion: enough to survive a redundancy in later working life, a long health problem, or a run of expensive years without having to borrow at high interest.

Who this term suits for an emergency saver: a worker planning for health shocks and redundancy in later working life, for example someone who wants to be able to stop work for a year after an illness without falling into high-interest debt.

FAQs

How does monthly saving grow?
Regular deposits grow because each deposit earns interest, and that interest then earns more interest.

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 interest pass $100,000 at 20 years?
Because 240 monthly deposits have each earned interest for up to 20 years, and the interest has compounded on itself. Interest is $111,020.45, or 48.1% of the fund, so nearly half the cushion was earned by time, not by deposits.

Is 20 years too long to forecast emergency costs?
For exact costs, yes: no one knows what a medical bill, a repair, or a period without work will cost in 20 years. The figure is still useful as a savings target, as long as it is reviewed every few years and adjusted for real prices.

Should emergency saving come before clearing a high-interest debt?
Usually a small emergency cushion comes first, so the next crisis does not force more high-interest borrowing, and then the expensive debt is cleared. Saving $500 a month while a card charges far more than 6% can cost more than it earns, so the two should be planned together.
