The Core Principle: Time-Based Compensation
Salary calculations convert between time periods using standard work-year assumptions.
Hourly to annual: Annual = Hourly Rate × Hours/Week × 52 weeks
Annual to hourly: Hourly = Annual Salary / (Hours/Week × 52)
Standard assumptions:
- Full-time = 40 hours/week
- Work year = 52 weeks (or 50 for unpaid leave)
- 2,080 hours per year (40 × 52)
Overtime calculation: Overtime Pay = Overtime Hours × Hourly Rate × Overtime Multiplier
Standard overtime is 1.5× (time-and-a-half). Some industries use 2× (double-time) for weekends or holidays.
How to Calculate Salary Conversions Manually
Hourly to annual example: £24/hour, 35 hours/week, 5 hours overtime at 1.5×
Regular weekly: £24 × 35 = £840 Overtime weekly: £24 × 1.5 × 5 = £180 Total weekly: £1,020 Annual: £1,020 × 52 = £53,040
Annual to hourly example: £45,000 salary, 37.5 hours/week
Annual hours: 37.5 × 52 = 1,950 Hourly: £45,000 / 1,950 = £23.08
Pay period conversions:
- Monthly: Annual / 12
- Bi-weekly: Annual / 26
- Weekly: Annual / 52
- Daily (5-day week): Annual / 260
£45,000 annual: Monthly: £3,750 Bi-weekly: £1,731 Weekly: £865 Daily: £173

Scenarios People Actually Run Into
The true hourly rate revelation. Your £45,000 salary requires 50 hours/week. True hourly: £45,000 / (50 × 52) = £17.31—lower than you thought.
The contractor comparison. A £400/day contract versus £65,000 salary. Contract: £400 × 220 working days = £88,000 gross, but no pension, holiday pay, or benefits.
The overtime illusion. 10 hours weekly overtime at 1.5× seems lucrative, but it's taxed at your marginal rate—actual value is lower.
The benefits gap. Two offers: £50,000 with 5% pension match versus £53,000 with no pension. First is worth £52,500 minimum in total compensation.
The part-time trap. Part-time at 20 hours/week doesn't mean half the annual salary—it's exactly half (or less, if benefits are reduced).
Trade-Offs and Decisions People Underestimate
Hours versus rate. A higher hourly rate working fewer hours may earn less than a lower rate working more hours. Calculate annual totals.
Gross versus net. Salary calculations show gross pay. Take-home pay depends on tax brackets, NI, pension deductions, and student loans.
Benefits valuation. Pension contributions, healthcare, holiday pay, and sick leave have monetary value often worth 10-30% of base salary.
Unpaid time off. If you take 2 weeks unpaid leave, use 50 weeks (not 52) for annual calculations.
Overtime sustainability. Consistent overtime increases income but has lifestyle costs. Calculate the break-even point where more money isn't worth less time.
Common Mistakes and How to Recover
Using 2,000 instead of 2,080 hours. 40 hours × 52 weeks = 2,080, not 2,000. The 80-hour difference affects calculations.
Ignoring benefits. A £50,000 salary with 5% pension match is worth £52,500 minimum. Compare total compensation, not just base pay.
Forgetting tax progressivity. Overtime and bonuses are taxed at your marginal rate, not your average rate. Net value is lower than gross.
Assuming consistent overtime. Calculating annual income with 10 hours/week overtime assumes that overtime is available every week.
Not accounting for unpaid leave. Contractors and hourly workers don't get paid for holidays. Factor in actual working weeks.

How This Calculator Works
Hourly to annual:
regularAnnual = hourlyRate × hoursPerWeek × 52
overtimeAnnual = hourlyRate × overtimeMultiplier × overtimeHours × 52
totalAnnual = regularAnnual + overtimeAnnual + bonus + commission
Annual to hourly:
hourlyRate = annualSalary / (hoursPerWeek × 52)
Pay period conversion:
monthly = annual / 12
biWeekly = annual / 26
weekly = annual / 52
daily = annual / (daysPerWeek × 52)
Effective hourly with overtime:
totalHours = (regularHours + overtimeHours) × 52
effectiveHourly = totalAnnual / totalHours

FAQs
How do I account for unpaid leave?
Reduce weeks per year from 52 to your actual working weeks (e.g., 50 for 2 weeks unpaid holiday).
Can this handle commission-based pay?
Yes—enter your base salary plus average monthly commission. The calculator annualizes the total.
What if my overtime rate is 2× instead of 1.5×?
Adjust the overtime multiplier in the settings. Some roles pay double-time for weekends or holidays.
Is this accurate for UK tax calculations?
The calculator shows gross pay only. For net pay, use a tax calculator that includes income tax, National Insurance, and pension.
How do I compare a salaried role to an hourly contract?
Convert both to annual gross income. Add employer benefits value (pension, holiday pay) to the salaried role for fair comparison.
Does this include holiday pay?
For hourly workers, UK law requires holiday pay in your hourly rate. The 52-week calculation assumes you're paid for holidays.
Can I calculate my effective hourly rate from salary?
Yes—enter your annual salary and actual hours worked (including unpaid overtime). The calculator shows your true hourly equivalent.
What's the difference between gross and net pay?
Gross is total earnings before deductions. Net is take-home pay after tax, NI, pension, and other deductions.
How do I negotiate salary using this calculator?
Know your market hourly rate. Convert offers to the same basis (annual or hourly) for comparison. Factor in benefits value for total compensation comparison.
What about employer National Insurance?
Employers pay NI on top of your salary. This is part of your "cost to employ" but doesn't affect your take-home pay directly.
How do bonuses affect my overall compensation?
Add expected annual bonus to base salary for total compensation. Note that bonuses are taxed at your marginal rate, potentially at a higher bracket.
What is a salary sacrifice scheme?
Exchanging part of your gross salary for benefits (pension, cycle to work, childcare vouchers) reduces taxable income, increasing your effective take-home pay.
How do I account for benefits when comparing jobs?
Assign values: pension match (% of salary), health insurance (monthly premium equivalent), holiday days (daily rate × extra days). Add to base salary for total compensation.
What's the difference between bi-weekly and semi-monthly pay?
Bi-weekly: every 2 weeks (26 paychecks/year). Semi-monthly: twice per month, same dates (24 paychecks/year). Bi-weekly means two months have 3 paychecks.
How do I calculate my effective tax rate?
Effective rate = total tax paid / gross income. This differs from marginal rate (rate on your last pound earned). Effective rate is always lower.
What is take-home pay versus gross pay?
Gross is before deductions; take-home (net) is what you actually receive after tax, NI, pension, student loans, and other deductions.
How do contractor rates compare to permanent salaries?
Contractors must cover their own benefits, holidays, and taxes. A rule of thumb: equivalent daily rate ≈ annual salary / 200 working days, plus 20-30% for benefits and overhead.
What about salary sacrifice schemes?
Trading gross salary for benefits (pension, childcare, cycle scheme) reduces taxable income and NI. Calculate net benefit considering what you give up and what you receive.
How do I calculate overtime value accurately?
Remember overtime is taxed at your marginal rate. £20/hour overtime at 40% marginal tax leaves only £12 take-home. Factor this into overtime decisions.
What's a good strategy for salary negotiations?
Research market rates, convert all offers to comparable annual totals, factor in benefits, and negotiate for total compensation rather than just base salary.
Additional Notes
Understanding your true compensation requires looking beyond the base salary number. Benefits, working conditions, growth opportunities, and work-life balance all have value. Convert everything to comparable terms—annual salary, hourly rate, or total compensation—to make informed decisions.
When negotiating, know your market value and be prepared to discuss total compensation, not just salary. The best negotiations create value for both parties by understanding what matters most to each side.
Practical Tips for Career Success
Track your accomplishments throughout the year for performance reviews and negotiations. Research market rates using multiple sources. Consider the full compensation package, not just salary. Build relationships that create opportunities for advancement. Invest in skills that increase your market value. Remember that job satisfaction includes more than just compensation.
Understanding Your Worth
Your value in the job market depends on skills, experience, demand, and location. Rare skills command premium compensation. Industry matters—the same role pays differently across sectors. Geographic location affects both salaries and cost of living. Regularly assess your market value by researching comparable positions. Invest in skills that are both in demand and aligned with your interests.
Understanding your compensation empowers better career decisions. Convert offers to comparable terms, factor in all benefits, and negotiate with confidence. Your time and skills have value—make sure you're getting fair compensation for what you contribute. Whether evaluating job offers or planning your budget, accurate salary conversion is essential. Use this calculator to understand exactly what your work is worth. Know your worth and negotiate from a position of knowledge. Accurate salary calculations are the foundation of informed career decisions. Understanding total compensation helps you make better career decisions at every stage. Know your value and negotiate accordingly for fair compensation. Fair pay for fair work is the foundation of career satisfaction. Understand your total compensation to make informed career choices.
