Setting a target amount is only the first step. How long it takes depends on what you already have set aside and the contribution you can keep up each month.
An example with numbers
To cover four months of essential expenses of $1,250, the target is $5,000. If you already have $2,000 and set aside $250 a month, you need 12 more months, with no interest or withdrawals.
Try it with your numbers
Enter your target and change only the monthly saving. If the time frame feels long, try an amount you could keep up even in a month with unexpected costs.
