DOCUMENTATION
Your salary is a lie.
Here's the maths that proves it.
TrueWage exists because every financial decision you make is based on a number that's fundamentally wrong. This page explains exactly how we calculate your real hourly rate, why we include things other calculators ignore, and why the methodology will make conventional financial advice uncomfortable.

UK unpaid overtime annually (TUC)
The Philosophy
ONS data shows the average UK full-time worker does 36.4 contracted hours per week. But the same data shows the average commute is 56 minutes per day — nearly 5 hours a week that nobody counts when calculating their hourly rate.
Then there's unpaid lunch breaks, getting ready for work, checking emails at home. The TUC estimates UK employees put in £35 billion worth of unpaid overtime annually. None of that makes it into anyone's "hourly rate" calculation.
And everyone calculates on gross salary when the average worker loses 25–30% to income tax, National Insurance, and student loans before seeing a penny. Someone on £35k thinking they earn £18/hour is lying to themselves. Factor in actual take-home and total hours committed to work — it's closer to £11–12. Every financial decision based on the wrong number leads to the wrong outcome.
TrueWage isn't a salary calculator with extra steps. It's a framework for understanding the real economics of your working life — built on the principle that everyone deserves to know the actual number, even when that number is uncomfortable.
Why This Exists
The standard financial advice everyone receives is: "look at your salary, work out your take-home, budget from there." But that calculation ignores the most important variable — how much of your life does this job actually consume?
Every existing salary calculator stops at gross-to-net. Nobody was showing the full picture: the real hourly rate accounting for every hour a job takes from someone's life, then translating that into what purchases really cost in working hours, what the FIRE timeline looks like, and whether career decisions make mathematical sense.
The gap became obvious when comparing two real scenarios: a £45k office job with a 90-minute commute versus a £40k remote role. On paper, the office job pays more. In reality, the remote role pays significantly more per hour of life committed. That insight changes everything — from job decisions to purchasing behaviour to retirement planning. TrueWage was built to make that insight available to everyone, for free.
Real Examples
These scenarios show why the "headline salary" is misleading — and why this tool exists.
SCENARIO 1: THE £5K PAY CUT THAT'S ACTUALLY A RAISE
OFFICE JOB
Salary: £45,000
90 min commute (round trip)
60 min forced lunch break
30 min getting ready
£150/month train pass
£40/month work lunches
TRUE RATE£11.47/hr
51.5 hours/week consumed. The '\u00A345k' masks the reality.
REMOTE JOB
Salary: £40,000
Zero commute
15 min lunch at home
No dress code overhead
£0 transport costs
£1 home lunch
TRUE RATE£15.82/hr
\u00A35k 'less' but 38% higher true wage.
SCENARIO 2: THE REAL COST OF A CAR
The average new car in the UK costs around £28,000. Most people calculate affordability against their gross salary. Here's what it looks like at different rates:
Gross rate (£18/hr)
1,556
hours of your life
(31 working weeks)
The fantasy
Net rate (£14/hr)
2,000
hours of your life
(40 working weeks)
Getting warmer
True rate (£11.50/hr)
2,435
hours of your life
(47 working weeks)
The reality
That £28k car costs almost an entire year of real working hours. And that's before insurance, fuel, maintenance, depreciation, and road tax — all paid in post-tax pounds, adding more true working hours on top.
SCENARIO 3: THE STRESS MULTIPLIER
"Stress can't be calculated" is what people say when they don't want to face the number. But stress has measurable financial downstream effects:
🍕Stress takeaways
£200/month
"Too tired to cook" 3x per week
🛍️Retail therapy
£150/month
"I deserve this" purchases
✈️Escape holidays
£300/month
Luxury trips to 'recharge'
🍷Decompression
£100/month
Post-work drinks, wine, treats
That's roughly £750/month — £9,000/year — in spending that exists primarily because of job-related stress. At a true hourly rate of £11.50, that's 782 hours of work spent recovering from work. The Stress & Burnout calculator quantifies this by asking about specific spending patterns and showing the compound opportunity cost when invested instead. Stress isn't immeasurable — its financial effects are precisely measurable.
The Calculator Suite
TrueWage isn't one calculator — it's an interconnected suite of 13 UK-specific financial tools, each attacking a different blind spot in how people understand their money. All use 2025/26 HMRC rates, all are free at the core level.
The True Hourly Wage calculator is the foundation — but every tool below feeds into the same question: what is the real cost of your working life?

True Hourly Wage Calculator
THE FOUNDATION
The calculator that started everything. Enter your gross salary and it strips away income tax (all bands including the £100k trap), National Insurance, student loan repayments (all 5 UK plans), commute costs, lunch break time, and prep time — then divides by the real hours your job consumes. The result: your actual hourly rate. For most people, it's 30–50% lower than they think. A 5-step guided flow that builds from salary to take-home to true hours to true rate to purchase converter.

How It's Calculated
Every formula uses 2025/26 HMRC rates. Click any card to expand the full methodology.
💰
Step 1: Real Take-Home Pay
▾Your gross salary is fiction. We strip it down to what actually hits your account.
INCOME TAX (ENGLAND & WALES)
tax = (income − 12,570) × 20% + (income − 50,270) × 20% + (income − 125,140) × 5%
All 2025/26 bands including the \u00A3100k\u2013\u00A3125,140 Personal Allowance trap where effective marginal rate hits 60%. Scottish rates applied automatically when selected.
NATIONAL INSURANCE
NI = (min(income, 50,270) − 12,570) × 8% + max(0, income − 50,270) × 2%
Class 1 employee rates. The drop from 8% to 2% above \u00A350,270 is one of the few cliff-edges that benefits higher earners.
STUDENT LOAN
Plan 2: (income − 27,295) × 9% | Plan 5: (income − 25,000) × 9%
All five plans supported. Student loan repayment reduces liquid cash available for wealth-building.
The £100k Trap: Earn between £100,000 and £125,140 and you lose £1 of Personal Allowance for every £2 earned. Effective marginal rate: 60%. The calculator visualises this cliff-edge.
CONTROVERSIAL
⏱
Step 2: Real Working Hours
▾Your contract says 37.5 hours. Your life says otherwise.
TRUE WEEKLY HOURS
realHours = contractHours + (commute × 5) + (lunchBreak × 5) + prepTime
We count ALL time your job takes from your life, not just the time you're 'working.'
COMMUTE TIME
Pure overhead. Only exists because the job requires physical presence. ONS average: 56 mins/day. If the job didn't exist, neither would the commute.
"I listen to podcasts" — you could do that at home too, without the packed train.
UNPAID LUNCH BREAKS
An office lunch break isn't 'your time.' You're geographically trapped in an area you didn't choose. Can't see family, run real errands, or eat when you're hungry. The break serves the employer's schedule.
"Everyone eats lunch" — at home, it's 15 minutes. At an office, it's 60 forced minutes. That 45-minute delta is 195 hours/year.
GETTING READY / PREP TIME
The corporate grooming ritual serves the employer. Ironing, dress code, makeup — time spent performing 'employability.' Working remotely, output is identical without any of it.
"I'd shower anyway" — you wouldn't iron a shirt or spend 30 minutes on appearance at 6am.
ANNUAL WORKING WEEKS
weeksWorked = 52 − annualLeave (inc. bank holidays) ≈ 46.4–47.2
UK statutory minimum is 28 days (5.6 weeks). Many forget bank holidays are included in that figure for 5-day workers.
🎯
Step 3: True Hourly Rate
▾The single number that should inform every financial decision.
THE CORE FORMULA
trueHourlyRate = (salary − tax − NI − studentLoan − commuteCosts − workCosts) ÷ (realWeeklyHours × weeksWorked)
Numerator: what actually hits your account. Denominator: the real hours your job consumes.
Monetary work costs are also deducted: commuting expenses, work clothing, professional subscriptions — anything that exists solely because of the job. The result is the purest measure of what one hour of life is worth when sold to an employer.
🛒
Step 4: Purchase Converter
▾Every purchase has a cost in hours of your life. Not the fake number \u2014 the real one.
LIFE-HOURS COST
hoursOfLife = purchasePrice ÷ trueHourlyRate
A \u00A3100 purchase at a \u00A312/hour true rate costs 8.3 hours of life \u2014 not 5.5 like the gross rate suggests.
Inspired by Vicki Robin's "Your Money or Your Life" — every pound spent is life energy exchanged. But most people calculate this against their fantasy gross rate. The difference permanently changes purchasing behaviour.
🔥
Step 5: FIRE Projection
▾When can you actually stop working? Not when your pension says.
FIRE NUMBER
fireTarget = annualSpending ÷ safeWithdrawalRate (2.5% UK-adjusted)
2.5% SWR instead of 4%. The 4% rule was calculated for US markets. UK investors face lower historical returns.
The FIRE projection integrates true hourly rate, actual savings capacity after real costs, and compound growth using historical S&P 500 returns (10.4% nominal). It also models the ISA bridge strategy — funding early retirement from ISAs until pension access at 57+.

Controversial Takes
These are the positions baked into how TrueWage works. Battle-tested across hundreds of debates.
CONTROVERSIAL
🔒
Pensions Are Government-Controlled IOUs
▾Deferred compensation under rules that change every few years. That's not 'wealth building' \u2014 it's a promise from politicians.
TrueWage doesn't include pension contributions in the true wage by default because they aren't liquid compensation. They can't be spent, invested freely, or accessed for decades. They're deferred promises from a system modified repeatedly.
HOW THE RULES HAVE CHANGED
2006
A-Day reforms
Lifetime Allowance introduced at £1.5M.
2010
LTA reduced
Cut from £1.8M to £1.5M. First major goalpost shift.
2012
Auto-enrolment
Government mandates pension participation. Opt-out, not opt-in.
2014
LTA slashed again
£1.5M → £1.25M. Then £1M in 2016.
2023
LTA 'abolished'
Headline says abolished. Reality: tax-free lump sum capped at £268,275.
2028
Min access age rises
55 → 57 confirmed. 58 already discussed.
The position: This isn't "never use pensions." Defined benefit schemes (NHS, teachers, civil service) are excellent. But for defined contribution pensions, ISAs offer the same tax-free growth with zero government interference and access at any age.

🏠
Your Commute Is Unpaid Labour
▾500+ hours a year for the average UK worker. Zero pounds paid.
The average UK commuter spends 56 minutes per day travelling (ONS). That's 4.7 hours per week an employer benefits from but doesn't pay for. "It's my choice" — no. It's a structural requirement that 2020 proved most knowledge workers don't need.
CONTROVERSIAL
🍽️
Lunch Breaks Are Employer-Imposed Downtime
▾60 minutes mandated. Geographically trapped. Can't see your family. But 'it doesn't count' apparently.
An office lunch break is 60 minutes of forced downtime in a location you didn't choose — can't see kids, run errands, or eat when actually hungry. At home, it's 15 minutes. That 45-minute daily delta is 195 hours per year of constrained time that only exists because of where the job requires you to sit.
CONTROVERSIAL
📊
The 4% Rule Doesn't Work in the UK
▾Designed for American markets. For UK investors, it's dangerously optimistic.
The "4% rule" comes from the Trinity Study using US data from 1926–1995. UK markets have historically returned less (FTSE 100: ~5–7% nominal vs S&P 500: 10%+). TrueWage uses 2.5% SWR. On £25k annual spending, that's a £1,000,000 FIRE target instead of £625,000. Uncomfortable, but honest.

😰
Stress Has a Calculable Financial Cost
▾'You can't put stress in a calculator.' You can \u2014 if you measure what it makes you spend.
The common objection: "stress is subjective, you can't quantify it." But stress has measurable downstream financial effects — takeaways, retail therapy, escape holidays, post-work drinks. That averages £750/month or £9,000/year, which is roughly 780 hours at the average true hourly rate.
The Stress & Burnout calculator doesn't ask "how stressed are you?" It asks about spending patterns and shows the compound opportunity cost if that money were invested. Stress itself isn't measurable — but its cost to your wallet absolutely is.

WFH Isn't a Perk \u2014 It's a Pay Rise
▾The exact financial value of remote work. For London commuters, it's equivalent to thousands.
Remote work eliminates wardrobe overhead, the morning routine, expensive lunches, stress spending, and commute costs. For the average London commuter, full remote equals a £5,000–£8,000 pre-tax rise in monetary savings. Factor in reclaimed time value, and it's closer to £12,000–£15,000 in true compensation. The WFH Savings calculator quantifies exactly how much.

Methodology FAQ
?
Why don't you include pension contributions in the true wage?
▾Click to expand
Pension contributions aren't liquid compensation. They can't be spent, invested freely, or accessed for decades. Including them inflates the 'true wage' with money that isn't controlled by the earner. An optional toggle exists for those who want it — but the default shows reality.
?
Isn't counting lunch breaks unfair?
▾Click to expand
At home, lunch is 15 minutes when you choose. At an office, it's 60 mandated minutes in a location you didn't pick. The 45-minute daily delta is 195 hours/year of geographically constrained time that only exists because of the job's structure.
?
My commute lets me read. It's not 'lost' time.
▾Click to expand
You could read at home too — without the packed train, the delays, or the 6am alarm. The question isn't whether commute time can be made productive. It's whether that time would exist without the job. It wouldn't.
?
Why 2.5% SWR instead of 4%?
▾Click to expand
The 4% rule comes from US data. UK markets have historically returned less, GBP isn't the global reserve currency, and UK cost-of-living inflation runs higher. A realistic FIRE number that's too high is better than an optimistic one that fails.
?
This doesn't account for work intensity. Isn't that a flaw?
▾Click to expand
Yes. Someone doing 40 hours at a relaxed role gets better value than someone doing 40 hours in a high-pressure environment. But work intensity is subjective and impossible to quantify objectively. Time is measurable. So we measure time.
?
Can stress really be measured in a calculator?
▾Click to expand
Stress itself can't. But its financial effects can. The calculator asks about spending patterns — takeaways, retail therapy, escape holidays — not feelings. These have exact pound values. It quantifies the downstream cost, not the emotion.
?
Why no employer benefits like healthcare or gym?
▾Click to expand
Benefits have value but aren't cash. A gym membership can't be invested. Dental coverage doesn't compound. TrueWage focuses on liquid compensation because that's what builds wealth.
