Quick Tips
Jump-start your understanding with these essential tips
Your effective tax rate changes with income level. Compare scenarios (salary increase, bonus, pension contribution) to see which saves the most tax. A £2,000 pension contribution might save you £400-£800 in tax depending on your income bracket.
Plan 1 vs Plan 2 loans have different thresholds and repayment rates. Plan 2 is more punitive for higher earners. Understanding your plan helps predict your actual take-home pay. Check your Student Loans Company statement if unsure.
Every pound you contribute to a pension reduces your taxable income pound-for-pound. This is powerful: a basic rate taxpayer saves 20p in tax per £1 contributed. A higher rate taxpayer saves 40p per £1.
Your effective tax rate = total tax ÷ total income. Your marginal rate = tax on your next £1 of income. The marginal rate is crucial when deciding whether a pay rise or bonus is worth it after tax. A 40% marginal rate means a £1,000 raise nets you only £600.
NI thresholds are usually updated in April. This tool uses one shared set of rules for planning, so treat results as guidance and check GOV.UK for the latest updates.
Step-by-Step Guide
Follow these steps to get the most from this tool
Start by selecting your tax year (2024/25, 2025/26, or 2026/27). Tax years in the UK run from April 6 to April 5 the following year.
Important: tax rules can change each year, but this calculator currently applies one consistent core ruleset for estimates. Use this for planning, then confirm final figures on GOV.UK or with payroll.
Simple rule: treat this as a decision-support estimate, not a final payslip calculator.
💡 Pro Tips:
- •Tax years don't align with calendar years—April 6 is the start of each tax year
- •Historical data is useful for comparing how your tax burden has changed year-to-year
- •Future tax year projections help plan for salary negotiations or retirement
Input your gross annual salary—the full amount before any deductions. This is the figure from your employment contract, or from your P60 if you're looking back at last year's income.
Gross salary includes your base salary plus any regular bonuses or allowances. This calculator focuses on employment income; if you have self-employment income, dividends, or investment income, those are handled differently for tax purposes.
The calculator will immediately show:
- Your Personal Allowance: £12,570 (2025/26)—the amount you can earn tax-free
- Taxable Income: Your salary minus personal allowance (and any pension contributions)
- Your Marginal Tax Rate: The tax rate on your next £1 earned
Next Step: Once you understand your net salary, explore how tax-efficient transport choices can further boost your savings. A long commute can cost £2,000-£5,000/year—see if switching modes saves money and taxes.
💡 Pro Tips:
- •If you're unsure of your salary, check your contract or latest payslip (it shows your annual salary)
- •Include any non-cash benefits with significant value (e.g., car allowance, stock options)
- •Bonuses should be included here if guaranteed; optional bonuses can be tested separately
Choose your student loan repayment plan if applicable. UK student loans are classified by what year you took them out:
- Plan 1: Taken out before September 2012. Repayment kicks in at £16,910 (2024/25). Lower repayment rate (9%) but fewer years of repayment.
- Plan 2: Taken out September 2012 onwards. Repayment starts at £27,285 (2024/25). Higher repayment rate (9%) but forgiven after 30 years.
- None: No student loans (typical for non-university-educated employees or loans already repaid).
The repayment threshold is the salary level at which you start paying back your loan. Below the threshold, no repayments are deducted from your paycheck.
Deeper Analysis: If you're considering whether university is worth it given student loan repayment, our Degree ROI calculator compares lifetime earnings across different qualifications and accounts for total loan repayment burden—useful context when planning your career trajectory.
💡 Pro Tips:
- •Not sure which plan? Unsure? Log into your Student Loans Company portal (www.slc.co.uk) to check your plan type
- •Plan 2 is generally less favorable for higher earners—a 40% taxpayer loses 9% to student loan repayments, making effective tax burden 49%
- •Student loan repayments stop if you fall below the threshold—useful for freelancers with variable income
Enter what percentage of your salary you want to contribute to a pension. Typical ranges:
- 0-5%: Minimal retirement saving (only if relying on state pension)
- 5-8%: Basic retirement saving + employer match (many employers match up to 5-8%)
- 10-15%: Moderate retirement saving (recommended for long-term security)
- 20%+: Aggressive retirement saving (high earners, self-directed savers)
Tax Magic: Pension contributions are deducted before tax is calculated. So a 10% contribution reduces your taxable income by 10%, saving you significant income tax. A basic rate taxpayer saves 20% of the contribution amount in tax; a higher rate taxpayer saves 40%.
Long-Term Planning: Use our Investment Growth Planner to model how different pension contribution levels compound over 20-40 years. A seemingly small 5% difference in contributions can mean £50,000-£100,000+ in retirement savings when accounting for compound growth and investment returns.
Maximizing pension contributions is one of the most powerful tax-saving strategies available.
💡 Pro Tips:
- •Check your employer's pension scheme—many offer matching contributions up to 5%. It's free money if you contribute at least 5% yourself.
- •Don't leave employer pension on the table. If your employer matches 5% and you don't contribute 5%, you're losing £2,500+ per year at a £50k salary.
- •Tax relief is automatic for workplace pensions, but self-invested personal pensions (SIPPs) require you to claim higher rate relief separately.
The calculator shows a comprehensive breakdown of your tax position:
| Gross Annual Salary | Your starting point |
| Pension Contribution (taken pre-tax) | Amount going to retirement savings |
| Taxable Income | What's left after pension and personal allowance |
| Income Tax | 20% on basic rate threshold, 40% on higher rate |
| National Insurance | 8% on earnings between £12,570–£50,270, then 2% above (rate cut from 12% in April 2024) |
| Student Loan Repayment | 9% of earnings above your threshold |
| Monthly Take-Home | Your actual salary after all deductions |
| Effective Tax Rate | Total tax burden ÷ gross salary (tells you true percentage of income lost to tax) |
| Marginal Tax Rate | Your tax rate on the next £1 earned (crucial for salary negotiations) |
Next Step: Use your actual take-home figure to plan your household budget. Our UK Budget Income Planner helps you allocate this income across essential spending (housing, food, transport) and savings/investments.
💡 Pro Tips:
- •Focus on your <strong>marginal tax rate</strong> when negotiating a raise. If it's 40%, a £10k raise nets you only £6k after income tax and NI.
- •Your <strong>effective tax rate</strong> is typically lower than your marginal rate—it's the average. A 40% marginal rate might be a 25% effective rate overall.
- •If you're near a tax band boundary, small salary tweaks can save hundreds. Example: earning £100,270 costs you higher rate tax on just £270; earning £50,000 avoids it entirely.
Test different scenarios to find the best tax strategy for your situation:
- Salary Increase: Simulate a promotion or pay rise. See your true net gain after tax and NI.
- Bonus Impact: Calculate how a year-end bonus affects your tax liability. Bonuses can push you into a higher tax bracket.
- Pension Contribution Increase: Try increasing your pension contribution by 5% or 10%. See how much tax you save.
- Income Drop: If you're planning to reduce hours or take unpaid leave, see the tax savings (and student loan relief).
Remember: Every scenario should be compared on a net basis (take-home pay), not just gross salary.
Apply Results to Other Decisions:
- Use your tax-optimized take-home to assess mortgage affordability with realistic income figures
- Compare your net income against living costs using the UK Budget Income Planner
- Factor your after-tax salary into career decisions (compare degree ROI vs apprenticeships)
💡 Pro Tips:
- •A 20% pension contribution might drop your effective tax rate from 28% to 22%—that's significant long-term wealth building.
- •If you're earning £50,250 and negotiating a £10k raise, you'll see a disproportionate tax hit (suddenly paying 40% marginal rate). Consider negotiating benefits instead.
- •Freelancers and contractors can "salary sacrifice" to pensions—this is an advanced strategy but worth exploring with an accountant.

Deep dives for advanced users
UK income tax is in bands. This means different parts of your pay are taxed at different rates.
Simple example: if your salary is £60,000, you do not pay 40% on all £60,000. You pay:
- 0% on the tax-free allowance
- 20% on the basic-rate part
- 40% only on the part above the higher-rate threshold
That is why your marginal rate and effective rate are different.
- Marginal rate: tax on your next £1
- Effective rate: average tax across all your income
This tool shows both so you can plan pay rises, pension changes, and monthly budgets more clearly.
National Insurance (NI) is separate from income tax, and it also reduces your take-home pay.
In this tool, employee NI is:
- 12% between the main NI thresholds
- 2% above the upper threshold
So if you are in the basic income-tax band, your next £1 can lose:
- 20% income tax
- 12% NI
- Total 32%
This is why many people feel their raise is smaller than expected after deductions.
Pension contributions can reduce your tax bill and increase long-term savings.
Why this helps:
- Your pension contribution is usually taken before tax in this tool
- That lowers taxable income
- Lower taxable income means less income tax paid now
If your employer matches your pension, that is extra money going into your pension pot.
This tool shows your monthly pension amount, tax relief impact, and employer contribution so you can see the full picture clearly.
For long-term planning, use the linked growth planner to test different contribution levels over time.
Student loan repayments depend on your plan type and salary.
Simple rule: if your pay is above your plan threshold, you repay a percentage of the amount above that threshold.
- Below threshold: no repayment
- Above threshold: repayment is taken automatically
That means two people on the same salary can have different take-home pay if they are on different plans.
Use this tool to compare “with loan” and “without loan” quickly so you can budget more accurately.
If you are unsure of your plan, check your Student Loans Company account first.
