1. How this calculator works
This calculator shows how rising costs affect your business. It applies your chosen cost increase percentage to your current monthly spending to reveal the real financial impact.

This tool helps you understand the true effect of cost increases so you can plan ahead, protect your margins, and make confident decisions about pricing and cashflow.
2. Enter your numbers into the calculator below:
Add your current monthly costs and the percentage increase you want to model — for example, a supplier price rise or a general increase in operating costs.
You can test different cost increase scenarios to see how they affect your monthly and annual spending, and how much extra cash your business will need.
Your results update instantly as you type — no spreadsheets, no formulas, no downloads. Just clear, real‑world insight into how rising costs affect your bottom line.
3. Worked Examples
Imagine your current monthly costs are £8,000, and your cost increase is 6%.
- New Monthly Costs: £8,000 × 1.06 = £8,480
- Monthly Increase: £8,480 − £8,000 = £480
- Annual Increase: £480 × 12 = £5,760
This means rising costs are adding £480 each month, or £5,760 each year, to your business — without you changing anything
4. Why this matters
Rising costs affect every part of your business — from materials and supplies to wages, rent, and overheads. Understanding the impact helps you make confident decisions about pricing, cost control, and cashflow planning.
