How to Forecast Your Bank Balance Month by Month (Free Tool)
A budget that only looks at this month answers the wrong question. What you actually want to know is: if I keep living like this, what does my balance look like in March? Can I absorb the car insurance renewal? When does the overdraft risk appear?
That's a forecast, not a budget — and you can build one in about ten minutes.
List income and outgoings by rhythm, not by amount
The trick to an accurate forecast is frequency. Salary is monthly, a phone contract is monthly, but the gym might be weekly, the car insurance yearly, and that dentist bill a one-off. Categorise each item by how often it hits, and let the tool project them onto a real calendar.
Yearly bills are the classic ambush: £300 in November feels invisible in July. A forecast makes it visible now.
Start from today's real balance
Open your banking app, take today's number, and use it as the starting balance. Every projected day after that is just: balance plus income landing that day, minus everything due. The output is a day-by-day ledger of your future — and the first time you see your projected balance dip negative two weeks before payday, you'll know exactly which expense to move.
Use the forecast to time decisions
Forecasts turn vague anxiety into scheduling. Want a £600 holiday? Slide it into the ledger as a one-off and watch what it does to the low point of the next three months. If the line stays above zero, book it without guilt. If it doesn't, the forecast tells you which month it fits.

Frequently asked questions
How is a budget forecast different from a normal budget?
A budget totals income and spending for a period. A forecast projects your actual balance forward day by day, so you can see low points, yearly-bill spikes, and the effect of a planned purchase before it happens.
Can I forecast weekly and yearly bills together?
Yes — Budget Companion lets each income source or expense repeat weekly, monthly, or yearly, or occur once, and combines them all in one projection.
Is Budget Companion really free?
Yes. Every feature — income, expenses, forecast chart, calendar, and ledger — is free. You just sign in with an email so your data can sync securely.
