Start with the prize
Use the current Lotto or EuroMillions jackpot, or enter a historical or hypothetical amount.
Start with a real UK Lotto or EuroMillions jackpot, then turn the headline prize into a life: home, cars, travel, family support, everyday comfort and the recurring costs that keep going long after the first shopping list is finished.
A £5 million win and a £100 million win create very different room for error, but the same basic question applies to both: how much disappears in the first year, and what does the new monthly lifestyle cost to keep running?
Use the current Lotto or EuroMillions jackpot, or enter a historical or hypothetical amount.
Put the big one-off decisions into one figure: property, renovations, cars, gifts, security and setup costs.
Monthly housing, travel, family support, staff, fun and everyday extras can matter more than the headline purchase over time.
Start with a current jackpot, choose a lifestyle starting point, then change every figure until it looks like your version of life after a win.
The calculator starts with a current UK Lotto or EuroMillions jackpot when live data is available. Choose either jackpot below, or enter your own amount.
Use a current jackpot above or type any lottery win amount you want to explore.
Property, renovations, vehicles, major gifts, security, debt repayment or other big early choices.
These only change the monthly cost fields below. Your jackpot and one-off spending stay untouched.
Insurance, maintenance, utilities, furnishing and ongoing property costs.
Insurance, finance, servicing, fuel, charging and replacement-cycle costs.
Regular holidays, weekends away, upgrades and spontaneous travel.
Monthly help, repeated gifts or support that becomes part of the normal budget.
Cleaner, gardener, maintenance help, childcare or other outsourced tasks.
Eating out, hobbies, tickets, gadgets and the everyday “yes” money.
Regular giving that you want built into the plan rather than left to chance.
Schooling, pets, subscriptions, entertainment and the general creep of a bigger life.
*The horizon figures are intentionally simple. They subtract the chosen recurring lifestyle from the capital left after one-off spending and assume no investment growth, inflation, tax, fees or future change in spending. Use the dedicated lifespan calculator for deeper modelling.
A bigger house or dream car is easy to notice because it arrives as a large number. The less obvious question is what happens when travel, family help, convenience and everyday spending become the new normal for 10 or 20 years.
Try the same jackpot three times. First build the life you would choose immediately. Then cut the recurring lifestyle to a comfortable version. Finally, exaggerate the luxury version. The contrast is often more useful than any single “perfect” answer.
The calculator becomes more interesting when the jackpot stays the same but the life around it changes.
Increase the one-off figure for a house or renovation, then keep monthly costs realistic to see what the property decision leaves behind.
Put gifts and immediate help in the one-off figure, then use the family field for support that might continue month after month.
Keep the initial splurge smaller and increase travel, fun and convenience to model a life built around time rather than possessions.
Yes. Choose the current UK Lotto jackpot at the top of the page and the calculator will use that amount as your starting point.
Yes. Choose the current EuroMillions jackpot at the top of the page. When both jackpots are available, the larger one is used as the initial starting point.
Yes. Yes. Type any amount you want or move the win slider. The calculator will then use your chosen figure.
Use the one-off field for large early decisions such as a property purchase, renovations, cars, major gifts, security improvements, debt repayment or setup costs that do not repeat every month.
Include costs that could become part of normal life: property running costs, transport, travel, family support, staff, hobbies, eating out, charity and a realistic buffer for everything else.
No. This page deliberately isolates spending so the trade-off is easy to see. The horizon figures assume no investment growth. Use the lottery money lifespan calculator when you want to add growth, inflation and a longer financial model.
No. It is simply the annual lifestyle cost divided by the capital left after your one-off spending. It is a comparison figure, not financial advice or a recommended investment-withdrawal strategy.
No. It is a lifestyle planning and comparison tool. It does not model personal tax, legal structures, adviser charges, investment fees or every consequence of a major win.
The most useful next steps are usually the money lifespan calculator, the full lottery win planner, the Investing & Wealth hub and the Security & Privacy hub.
Continue from lifestyle spending into longer-term planning, wealth, privacy and other lottery tools.
