Comparing two Gibraltar contracting offers on net income, not just day rate
A higher day rate doesn't always mean a better outcome once contract length, expected downtime between contracts, and social insurance are taken into account. This calculator compares two Gibraltar contracting offers side by side on actual net income rather than the headline rate.
What's compared
- The day rate and expected duration of each contract
- Self-employed social insurance at 20% of earnings for each, subject to the same £1,583.40 minimum and £2,923.83 maximum annual contribution
- Income tax under the lower of ABS or GIBS for each contract's expected income
- The resulting net income for each offer, shown side by side
