Hour-a-day wealth.

Value of extra hour calculator quantifies long-term wealth from one extra productive hour daily. 25/hour × 1 hour × 5 days × 50 weeks × 30 years invested at 7% = 652,000. Single hour daily transforms career wealth. Whether through earning, skill-building, exercise, or investing - the extra hour compounds dramatically.

Example: 1 extra productive hour daily at 25/hour value (could be earning, learning, exercise, sleep). 5 days/week × 50 weeks × 30 years = 7,500 extra hours over career. Value compounded at 7%: 652,000 wealth. Single hour daily = life-changing accumulated value.

Extra hour use cases: (1) Earning (consulting, side hustle, overtime). (2) Skill-building (course, reading, certifications). (3) Exercise (long-term health = financial value). (4) Sleep (improved next-day productivity). (5) Networking (career advancement). (6) Investing/financial planning (compound returns). Each compound differently. Time saved (no commute, etc.) reinvested in productive activities = massive lifetime impact. Most overlooked personal investment: optimising daily time use. Save 1 hour daily through automation, delegation, or better habits = 500k+ lifetime value.

Run it with sensible defaults

Using your hourly value of 25, extra hours per day of 1, days per week of 5, weeks per year of 50, the calculation works out to 590,379.91. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Your Hourly Value (£), Extra Hours per Day, Days per Week, Weeks per Year, and Years Compounded — do not pull with equal force. Hours and hourly rate both appear to matter equally, but in practice the rate is the bigger lever because it applies to every hour. A modest rate uplift beats a modest hour increase almost every time.

How the math works

Annual extra income invested at compound rate over years (annuity FV). The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using the result to decide

The figure gives you a threshold. Below it, paying someone else usually wins. Above it, doing it yourself usually wins. The number isn't destiny — some tasks are genuinely worth doing personally — but it sets the default.

What this doesn't capture

Hour-for-money math misses the tasks you enjoy and the ones that build skill. The number is an efficient-markets view of your time; real decisions about what to do yourself vs outsource should also weigh what you learn and what you enjoy.
