Penny PaydayThe example
One person, paid $900 every other Friday, with these monthly bills:
| Bill | Due | A month |
|---|---|---|
| Rent, your share with a roommate | 1st | $750 |
| Electric and internet | 25th | $120 |
| Phone | 12th | $40 |
| Monthly bus pass | 1st | $70 |
| Streaming and apps | 15th | $20 |
| Card minimum | 18th | $40 |
| Total | $1,040 |
Two checks a month, so each check covers half: $1,040 ÷ 2 = $520. The check that lands before rent is due won't always hold exactly half; here's how to even it out.
No car in this example: a $70 bus pass instead. A car would add insurance and gas, and at this check size that comes straight out of the daily number.
One check, start to finish
| Take-home check | $900 |
| Half the monthly bills | −$520 |
| Set aside | −$30 |
| Groceries for two weeks | −$150 |
| Left for day to day | $200 |
| ÷ 14 days = $14.29, rounded down | $14 a day |
| Left over at payday (14 × $14 = $196) | $4 |
$14 a day covers everything not on the list: food out, coffee, a store run. Spend less one day and the days after get a little more; spend more and they get less. To see it with your own numbers, open this example in the calculator and change what's different.
Where the $900 goes
| Part | Amount | Share of the check |
|---|---|---|
| Bills (half the month) | $520 | 58% |
| Set aside | $30 | 3% |
| Groceries $150 | $150 | 17% |
| Day to day, including the $4 left over | $200 | 22% |
| Total | $900 | 100% |
Shares are rounded to whole percents.
Compared with the 50/30/20 rule of thumb
The 50/30/20 rule of thumb splits take-home pay into 50% needs, 30% wants and 20% savings. On a $900 check that's $450 for needs, $270 for wants and $180 for savings.
In the example, needs (the bills, groceries) take $670, 74% of the check. Half the rent alone is $375, 42%. When rent is that big a share, the rule's split doesn't fit, and the set-aside starts smaller ($30, 3%). It's a rule of thumb, not a rule; the daily number is what tells you whether the check works.
If your numbers are different
- Every extra $100 of bills on this check takes about $7 off the daily number ($100 ÷ 14 = $7.14).
- Two months a year bring a third check: $2,700 that month instead of $1,800. Find your 3-paycheck months.
- Hours change from check to check? Plan on your lowest regular check and treat anything above it as extra when it lands.
- Paid weekly instead? A $450 weekly check is the same money; plan it over 7 days.
Questions
How much is $900 biweekly a month?
$1,800 in most months, from two checks. Averaged over the year it's $1,950 a month (26 checks ÷ 12 months), because two months bring a third check of $900.
How much is $900 biweekly a year?
$23,400 in take-home pay over 26 checks. Some years have 27 paydays, which makes it $24,300.
How much can I spend a day on $900 biweekly?
There's no single right number: it's what's left after the bills due before your next payday and what you plan to set aside and buy, divided by 14. In this made-up example it's $14 a day. Try yours in the calculator.
Penny does this with your real numbers. Type your check and bills once; every payday she splits the new check and gives you one number a day.
