  For large Pound Sterling sums, compare the social security contribution output for United Kingdom against a rough mental estimate first; if the two are far apart, re-check the rate and the amount before trusting either number for a decision or a commitment.

• A percentage entered as a whole number where a decimal is expected (15 versus 0.15) is off by ×100 — the most common single error in rate fields. Check which form the United Kingdom Social Security Contribution field expects before you type.

• Gross and net are different numbers: a Pound Sterling salary quoted for United Kingdom is normally gross, and the Social Security Contribution result only matches your payslip after United Kingdom deductions and contributions are subtracted. Confirm which side each input represents.
