How Salary Calculations Work
Converting Between Pay Periods
Understanding how your pay converts between different time periods helps you compare job offers, negotiate raises, and budget effectively. The calculations are straightforward but important to get right:
Annual Salary Conversions: Hourly to Annual: Hourly Rate × Hours per Week × 52 weeks = Annual Salary Annual to Hourly: Annual Salary ÷ 52 weeks ÷ Hours per Week = Hourly Rate Annual to Monthly: Annual Salary ÷ 12 months = Monthly Gross Pay Biweekly (every 2 weeks): Annual Salary ÷ 26 pay periods = Biweekly Gross Pay Semi-Monthly (twice per month): Annual Salary ÷ 24 pay periods = Semi-Monthly Gross Pay
Calculation Example
Let's convert a $75,000 annual salary to different pay periods:
- Annual: $75,000
- Monthly: $75,000 ÷ 12 = $6,250/month (gross, before taxes)
- Biweekly: $75,000 ÷ 26 = $2,885/paycheck (26 paychecks per year)
- Weekly: $75,000 ÷ 52 = $1,442/week
- Hourly (40-hour week): $75,000 ÷ 52 ÷ 40 = $36.06/hour
- Daily (8-hour day): $36.06 × 8 = $288.46/day
Important: These are gross amounts (before taxes and deductions). Your actual take-home pay (net pay) will be 70-80% of gross depending on your tax bracket, state, and benefits deductions.

Understanding Different Pay Structures
Biweekly vs. Semi-Monthly
Many people confuse these, but they're different:
Biweekly (26 paychecks/year):
- Paid every 2 weeks (every other Friday, for example)
- 26 paychecks per year
- Two months each year you get 3 paychecks instead of 2 (bonus months!)
- Example: $75,000 annual = $2,885 per paycheck
Semi-Monthly (24 paychecks/year):
- Paid twice per month (1st and 15th, for example)
- 24 paychecks per year
- Same number of paychecks every month
- Example: $75,000 annual = $3,125 per paycheck
Notice the semi-monthly paycheck is larger ($3,125 vs $2,885) even though annual salary is the same, because you're getting 24 checks instead of 26.
Salary vs. Hourly
Salary (Exempt):
- Fixed annual pay regardless of hours worked
- No overtime pay (usually)
- Benefits typically better (health insurance, PTO, retirement)
- Professional roles, management, administrative positions
- Example: $80,000/year whether you work 40 or 50 hours/week
Hourly (Non-Exempt):
- Paid only for hours worked
- Overtime pay (1.5× rate) for hours over 40/week
- No pay if hours are cut or you're sent home early
- Retail, service, entry-level, skilled trades
- Example: $25/hour × 40 hours = $1,000/week, but $37.50/hour for overtime
Using Salary Information for Career Decisions
Comparing Job Offers
When comparing jobs, convert everything to the same basis (annual salary) and factor in total compensation:
Offer A: $70,000 salary + $8,000 in benefits (health, 401k match) = $78,000 total compensation
Offer B: $75,000 salary + $3,000 in benefits = $78,000 total compensation
Both are equal when you factor in benefits. Now consider: commute time (1 hour daily = 260 hours/year, worth $7,500-15,000 depending on your hourly value), work-life balance, growth opportunities, and job security.
Negotiating Salary
Use these conversions to negotiate smartly:
- Know your hourly value: $60,000 annual = $28.85/hour. Does your work justify that rate for your market?
- Calculate raise impacts: 5% raise on $60,000 = $3,000/year = $115/paycheck (biweekly) = $1.44/hour
- Compare market rates: Research salary ranges for your role/location on Glassdoor, LinkedIn, Payscale
- Total compensation matters: $5,000 lower salary with better benefits might actually be worth more
Raise vs. New Job
Statistically, changing jobs gets you bigger pay increases than internal raises:
- Average annual raise (staying): 3-5% ($60,000 → $61,800-63,000)
- Average raise (job change): 10-20% ($60,000 → $66,000-72,000)
- Cost of job change: Lost seniority, benefits reset, adjustment period, potential commute change
However, if you're underpaid by 20-30%, even switching jobs once can permanently put you on a higher trajectory. Someone at $50,000 who should be at $65,000 loses $15,000 every year they wait.
Frequently Asked Questions
What's the difference between gross and net salary?
Gross salary is your total pay before any deductions (the number in your offer letter). Net salary (take-home) is what actually hits your bank account after federal taxes (10-37% depending on income), state taxes (0-13% depending on state), Social Security (6.2%), Medicare (1.45%), health insurance, 401k contributions, and other deductions. Most people's net is 70-80% of gross. For example, $75,000 gross might be $52,500-60,000 net ($4,375-5,000/month take-home).
How do I calculate my hourly rate from salary?
Divide your annual salary by 2,080 (52 weeks × 40 hours). For example, $60,000 ÷ 2,080 = $28.85/hour. This is useful for comparing salary jobs to hourly jobs, calculating your true cost per hour if you're a freelancer, or understanding what you're really earning per hour worked (including overtime). If you regularly work 50 hours/week instead of 40, your effective hourly rate is lower: $60,000 ÷ (52 × 50) = $23.08/hour.
Is it better to be paid biweekly or monthly?
Biweekly is generally better for budgeting because you get paid more frequently and have better cash flow throughout the month. The "3 paycheck months" (happens twice per year with biweekly) can be used for saving or paying down debt. Monthly paychecks require more disciplined budgeting since you have to stretch one paycheck 30-31 days. However, monthly might simplify paying monthly bills. From a purely financial perspective, the frequency doesn't matter—annual total is the same—but biweekly is psychologically easier for most people.
Should I ask for a higher salary or more benefits?
It depends on the employer's flexibility and your needs. Companies sometimes have more wiggle room on benefits than base salary (due to salary bands). Consider: If you're young and healthy, prioritize salary (you'll build wealth faster). If you have a family, good health insurance is worth $5,000-15,000/year. Extra vacation days are worth 1-2% of salary per week (50 weeks/year, so 1 week = 2% of annual pay). 401k match is free money (50-100% return). Sign-on bonus or annual bonus can increase total compensation without affecting base (future raises are calculated from base). Professional development budget ($2,000-5,000/year) pays for growth.
How much of a raise should I expect annually?
Typical annual raises by performance: Cost of living adjustment (meets expectations): 2-3%, Good performance: 3-5%, Exceptional performance: 5-8%, Promotion: 10-20%. However, these vary by industry, company size, and economic conditions. Tech companies often give larger raises (5-10%) while government and education typically give smaller raises (1-3%). If you're not getting at least 3% annually, you're losing purchasing power to inflation. If you haven't had a raise in 2+ years or are below market rate, this is a strong negotiating position.
What percentage of salary should I save?
General guidelines using gross salary: Minimum (20s-30s): 10-15% into retirement/savings. Recommended (all ages): 15-20% into retirement/savings. Aggressive (FIRE/early retirement): 30-50%+ into investments. Popular breakdown (50/30/20 rule): 50% needs (housing, food, utilities), 30% wants (entertainment, dining out), 20% savings/debt payoff. On $75,000 gross ($52,500 net), that's $10,500/year savings ($875/month). Adjust based on your goals and current debt.
