In a budget, actuals are the real income and expense figures your business records as transactions actually occur, as opposed to the estimated numbers you planned for. If your budget projected $50,000 in office supplies for the quarter and you spent $47,200, that $47,200 is the actual. The same holds on the revenue side: forecasted $200,000 in sales but invoiced $185,000, and $185,000 is your actual. Comparing actuals against the budget is how you find out where the plan held up and where it didn’t.
Where Actuals Come From
The main source is your general ledger, the master record of every financial transaction. Each entry posts as a debit and a credit, keeping the books balanced and building a complete trail of activity. Supporting records feed in from there. Accounts payable tracks vendor invoices and payments, producing expense actuals for rent, utilities, materials, and the like. Accounts receivable tracks customer invoices and incoming payments, producing revenue actuals.
Those numbers are only useful if they’re right. Monthly bank reconciliations catch duplicate payments, transposed digits, and misclassified transactions before they distort the month-end figures. For companies subject to audit, whether internal controls are strong enough to produce reliable data is itself part of what auditors evaluate.1Public Company Accounting Oversight Board. AU Section 150 – Generally Accepted Auditing Standards
When a Number Becomes an Actual
Your accounting method decides when a transaction lands in your books, and that changes what any given month’s actuals look like.
Under the cash method, revenue is recorded when you receive payment and expenses when you pay them. A customer buys $10,000 of product in March but pays in April, and that revenue shows up in April’s actuals. Under the accrual method, revenue is recorded when earned and expenses when incurred, no matter when cash moves. That same March sale posts to March, because that’s when you delivered.2Internal Revenue Service. IRS Publication 538 – Accounting Periods and Methods
Accrual matches revenue with the expenses that produced it in the same period, which gives a truer read on profitability month to month. Cash is simpler but produces swings; a month can look strong purely because several late invoices were paid at once.
Not every business picks freely. Corporations and partnerships averaging more than $26 million in gross receipts over the prior three years generally have to use accrual. Smaller businesses, S corporations, and certain partnerships can use either.2Internal Revenue Service. IRS Publication 538 – Accounting Periods and Methods Whichever you use, your budget and your actuals need to follow the same method. A cash actual measured against an accrual budget produces variance numbers that mean nothing.
Comparing Actuals to Your Budget
The gap between what you planned and what happened is a variance. The math is straightforward: actual minus budgeted.
What throws people is that favorable and unfavorable flip depending on which side of the ledger you’re on. On revenue, coming in above budget is favorable. On expenses, coming in below budget is favorable. Budgeted $100,000 in monthly sales and brought in $115,000? That’s a favorable $15,000 variance. Allocated $10,000 for digital ads and spent $9,200? That’s a favorable $800. Same sales team at $85,000, or the ad spend at $11,500, and the variance runs the other way.
Which Variances Are Worth Investigating
Not every gap deserves attention. Most organizations set a materiality threshold, often 5% to 10% of the line item or a fixed dollar amount, that triggers a review. A $500 miss on a $5,000 line is worth a look. The same $500 on a $500,000 line isn’t. Set the threshold to the scale of your business and the category involved, and don’t spend afternoons chasing rounding.
How Often to Review Actuals
Monthly is the standard cadence, and it lines up with the general ledger close and financial statement issuance. Quarterly and year-to-date views layer on top and show whether trends are holding.
One timing quirk worth knowing about: biweekly payroll rarely lines up with calendar months. To keep monthly labor actuals from swinging based on whether a pay date fell before or after month-end, the accounting team posts an accrual at month-end estimating the payroll earned but not yet paid, then reverses it when the actual payroll posts the following month.
A standard budget-versus-actuals report shows each line with the budgeted amount, the actual, the dollar variance, and the variance as a percentage. The percentage column normalizes the comparison. A $2,000 overage reads very differently on a $10,000 line than a $200,000 line, and the percentage makes that obvious at a glance.
Using Actuals to Build a Better Budget
Past actuals are the raw material for next year’s plan. Twelve to twenty-four months of historical performance gives you realistic baselines instead of the optimistic revenue targets and understated expenses that plague many budget cycles. If travel has blown the budget three years running, the budget is wrong, not the travelers.
Rolling Forecasts
A rolling forecast doesn’t wait for the annual cycle. Finance updates projections on a set cadence, usually monthly or quarterly, always looking a set period ahead like 12 or 18 months. Each update replaces the oldest month’s projections with the newest month’s actuals, keeping the forward view anchored in what’s actually happening. If revenue is running 15% below budget six months in, the rolling forecast rewrites the back half of the year on that basis rather than holding out for a second-half rebound that isn’t coming.
Adjusting for Inflation and Known Cost Changes
Prior-year actuals need adjustment before they become next year’s assumptions. Raw materials up 8% last year, plugged into the new budget without an inflation bump, guarantees an unfavorable variance from day one. Same for health insurance premiums increasing 6%, contractual lease escalations, and rising shipping rates. Actuals tell you what happened; smart forecasting builds in what’s already changing.
Responding to an Unfavorable Variance
Spotting a variance is the easy part. The work is figuring out whether it’s a one-time event or something structural, then acting on it.
Start with root cause. An unfavorable expense variance might come from a vendor price increase, an unplanned repair, or a department simply overspending. Each calls for a different response. A vendor price hike may trigger a procurement review or renegotiation. An unplanned repair is a one-time hit and probably doesn’t change the forecast. Chronic overspending in a department points to tighter approvals or a reallocation.
On the revenue side, a shortfall could mean a product line is underperforming, a key customer reduced orders, or seasonal patterns shifted. Responses range from adjusting sales targets to redirecting marketing spend to cutting costs elsewhere to protect the bottom line. The worst response is none. Unfavorable variances left alone month after month are how businesses end the year with results that look nothing like the plan.
How Long to Keep the Underlying Records
The transactions behind your actuals also serve as tax records if the IRS ever asks. Retention periods vary with the situation:
- Three years for most tax return records, measured from the date you filed.
- Four years for employment tax records, measured from the date the tax becomes due or is paid, whichever is later.
- Six years if you fail to report income exceeding 25% of the gross income shown on your return.
- Seven years if you claim a deduction for bad debt or worthless securities.
- Indefinitely if you file a fraudulent return or don’t file at all.
The IRS guidance is to keep records as long as they’re needed to prove the income or deductions on a return.3Internal Revenue Service. How Long Should I Keep Records Many businesses default to seven years for everything, since sorting records by category costs more time than the storage saves. Employment tax records carry their four-year minimum regardless.4Internal Revenue Service. Recordkeeping
