Variance Analysis for UK Businesses That Want to Understand Why Numbers Differ
Your actual results will never match your budget perfectly, but knowing why they differ is what matters. ABM Chartered Accountants provides monthly variance analysis that explains the gap between plan and reality so you can act on facts and adjust with confidence.
Every Variance Quantified, Explained, and Acted Upon
Variance analysis is the process of comparing your actual financial results against your budget or forecast and investigating the reasons behind every significant difference. It turns raw numbers into insight. ABM Chartered Accountants produces monthly variance reports that tell you not just what happened, but why it happened and what you should do about it.
Our ICAEW and ACCA qualified accountants compare your actual revenue, costs, and margins against your budget each month. We quantify favourable and unfavourable variances, investigate the root causes, separate one-off events from developing trends, and recommend specific corrective actions where your plan is at risk.
What Our Variance Analysis Covers
From budget comparison to corrective action, here is how ABM Chartered Accountants turns the gap between your plan and your results into actionable business intelligence.
Budget vs Actual Reporting
Comparing your actual financial results against your budget each month to quantify every difference.
Revenue Variance Analysis
Investigating why your actual revenue differs from budget by volume, price, mix, or timing.
Cost Variance Investigation
Identifying which costs came in above or below budget and explaining the reasons behind each one.
Margin Drift Detection
Spotting when your gross or net margins are shifting away from plan and pinpointing the cause.
Trend Identification
Tracking variances over multiple months to separate one-off events from developing patterns.
Corrective Action Recommendations
Advising on specific steps to address unfavourable variances and protect your planned profit.
Catch the Drift Before It Becomes a Problem
Small variances in one month can become serious problems if left unchecked. A cost overrun that looks minor in January can compound into a significant loss by December. ABM Chartered Accountants catches these movements early, explains their cause, and gives you the information you need to respond before the impact grows.
Variance analysis also tells you when things are going well and why. Favourable variances are just as important to understand. If a product line is outperforming, you want to know whether it is sustainable or a one-off so you can decide whether to invest further or hold steady.

Frequently Asked Questions
Here are answers to the variance analysis questions we hear most often. Contact our team for guidance.
What is variance analysis?
Variance analysis is the process of comparing your actual financial results against your budget or forecast. It quantifies the differences, investigates the reasons behind them, and classifies them as favourable or unfavourable. ABM Chartered Accountants uses variance analysis to help you understand and improve your financial performance.
What is a favourable versus an unfavourable variance?
A favourable variance means the actual result is better than budget, such as higher revenue or lower costs. An unfavourable variance means the actual result is worse than budget, such as lower revenue or higher costs. Both need investigating because not all favourable variances are sustainable.
How often should variance analysis be done?
Monthly is recommended. This gives you enough detail to spot trends early and enough time to take corrective action before variances compound. ABM Chartered Accountants produces your variance report as part of your monthly management accounts so it is always current and actionable.
What causes revenue variances?
Revenue variances can be caused by changes in sales volume, pricing, product or service mix, timing of invoicing, or customer behaviour. For example, your revenue could be below budget because you sold fewer units, or because you discounted more than planned. We identify which factor is driving the difference.
Do I need a budget before I can get variance analysis?
Yes. Variance analysis compares actual results against a plan, so you need a budget or forecast to measure against. If you do not have one, ABM Chartered Accountants can build your budget first and then begin monthly variance reporting once the plan is in place.
How much does variance analysis cost?
Fees depend on the complexity of your business, the number of cost centres or departments, and the level of detail required. Variance analysis is usually included in our management accounts service. Contact ABM Chartered Accountants for a quote based on your reporting needs.
