Most people know their bank balance to the dollar right now. What it will be in six months is a guess. But a guess is not what you need. You need a projection: a line drawn from today’s balance through every income deposit and bill payment you already know about, out to the end of the year. That is a cash flow forecast, and this guide shows how to build one in Recurna Flow without touching a spreadsheet.
What a balance projection actually is
A projection is not a budget. A budget tracks category totals — groceries, transport, dining. A projection tracks your balance: the number in your account on any given day.
Those are different questions. A budget might say your groceries are on track.
A projection will tell you whether the Friday before your insurance renewal is
going to leave your account at $340 or $2,100. The difference matters, and
the budget cannot answer it.
You build a projection by starting from your current balance — one real number — and running every recurring transaction you already know about forward through time. Your pay comes in biweekly, your rent leaves monthly, your subscriptions trickle out on scattered dates. The projection does the arithmetic and draws the resulting balance as a line.
What you need before you start
Three things:
- Your current balance. Check right now, not your memory from last week.
- Your recurring income. Each amount, which account it lands in, and how often — biweekly, monthly, weekly.
- Your recurring bills. Each amount, the account it leaves, and the real frequency. Annual bills — insurance, property tax — go in on the actual month they hit, not smoothed into monthly fractions.
That is the full input set. The forecast does not need your spending categories or your savings goals. It needs the things that are already happening whether or not you think about them.
How to build the projection in Recurna Flow
- Open the Forecast page. Pick the account you spend from day-to-day — the one your pay lands in and your bills leave from.
- Set the date range to Next 1Y. This gives you 52 weeks: long enough to catch every annual bill and the seasonal patterns that a quarterly view misses.
- Confirm your starting balance. Recurna Flow anchors the forecast to the current balance the account shows. If it needs a correction, update it before you add anything else — it is the number every projection is relative to.
- Add your income. For each income source: the amount, the account, and the cadence. Biweekly pay should be set as biweekly, not approximated as two monthly amounts — the difference is whether the forecast correctly shows the three-paycheque months that arrive roughly twice a year.
- Add your recurring bills. Rent, loan payments, insurance, subscriptions,
and any annual bills. For the annuals, enter the actual amount on the actual
month they hit. A
$1,500insurance renewal in September should show up as a$1,500dip in September, not as$125every month. - Set an account floor — the minimum balance you want to stay above. Zero
is not a safe floor; zero means you are one unexpected bill away from trouble.
Your floor might be
$500, or one month of expenses. Define it now so the forecast has something to measure against.
The projection draws immediately as you add transactions. You will see a week-by-week line showing where your balance is headed.
How to read what you built
Do not look at where the line ends. A healthy number in week 52 tells you nothing about the weeks in between. Look for the lowest point — the week where your balance dips the most.
Find it in the week-by-week breakdown below the chart. Check whether it stays above your floor. If it does, the year holds together. If it dips under, you have found the exact week that needs attention — now, with months of warning, before it becomes a problem.
A common surprise: months that look quiet in aggregate often contain a clustering of bills in a specific week. A biweekly pay cycle means some calendar months carry two paydays and some carry three. A quarterly premium and an annual renewal can land in the same month. The projection surfaces all of this; a monthly budget hides it.
Be honest about the inputs. A projection built on rounded-down grocery estimates and optimistic side-income assumptions will show a line that looks great and means nothing. Enter the boring true numbers — the forecast’s value is only real if it reflects your actual situation.
What to do when the line dips
When a week drops close to your floor, the projection has done its job: it found the problem early, while it is still cheap to solve.
That is when the projection turns from a picture into a question. What if I
push the big purchase a month? What if I start setting aside $200 a week now?
What if the new car payment lands on top of all this? You do not have to guess
— you can test the change in the simulation panel and watch what it does to
that tight week, before you commit to anything.
Building the projection is the foundation. Everything after — affording the thing, weathering the slow quarter, deciding when — is read off the line you just drew.
Free accounts get a rolling 12-week forecast — enough to catch the next quarter’s clustering and to feel how the weekly model works. Stretching to a full 12 months, where the annual bills and seasonal patterns live, is a Recurna Flow Pro feature. See what the longer view covers at Recurna Flow Pro.
