Common Mistakes
-
Mixing units
- Confusing pounds sterling (£) with pounds weight (lb). Always confirm context.
-
Forgetting to convert percent to decimal
- 20% is 0.20, not 20. Don’t multiply 50 × 20.
-
Rounding too early
- For money, round at the final step to two decimals (£10.00). Avoid mid-calculation rounding errors.
-
Misreading VAT price basis
- Is £50 the price before VAT (net) or after VAT (gross)? 20% applies differently.
-
Skipping reasonableness checks
- 20% of 50 should be less than 50 and about one-fifth. If your result is bigger than 50, recheck.
-
Ignoring regional rules
- VAT/tax rates vary. UK standard VAT is 20%, but some items use reduced or zero rates.
Warnings
- VAT and tax laws change. Always confirm current rates from official sources.
- Currency exchange rates fluctuate. Use a reliable, real-time source.
