Here's a detailed guide on the money and economy system in Grand Theft Auto V (GTA V), covering both the single-player story mode and the multiplayer component, GTA Online:
Single-Player Mode (Story Mode):
Earning Money:
•Missions: The primary source of income. Completing story missions, heists, and side missions (Strangers and Freaks) grants money.
•Heists: These are high-risk, high-reward activities. The big heists like "The Jewel Store Job," "The Bureau Raid," etc., can yield substantial cash, especially if you choose the right approach.
•Assassinations: Franklin can undertake assassination missions which, if timed correctly with stock market investments, can lead to significant financial gains.
Investments:
•Stock Market: Through Lester's assassination missions, you can manipulate stock prices. Buying stocks before an assassination mission and selling them afterward can multiply your money.
•Lester's Assassinations: Each assassination affects a different company's stock, so timing your buys and sells is crucial.
•Robberies, Stealing Cars, and Selling Them: You can rob stores or steal high-value cars to sell at Los Santos Customs. However, this method is less efficient for large sums.
•Races, Deathmatches, and other Activities: Participating in these can earn you some cash, though not as much as heists.
Spending Money:
•Properties: Buying properties like houses, businesses, or vehicle garages can provide passive income or serve other gameplay benefits like missions or discounts.
•Vehicles: Cars, boats, planes, and bikes can be bought for personal use or to complete missions more efficiently.
•Weapons & Ammo: Upgrading your arsenal is crucial, especially before tough missions or heists.
•Character Upgrades: Tattoos, clothes, and other personal items don't affect gameplay but add to character customization.
Tips: 
•Save Before Heists: You can save before a heist to retry if the outcome isn't financially favorable.
•Stock Market Manipulation: Use Lester's missions to maximize profits from the stock market.
GTA Online:
Earning Money:
•Missions and Heists: Similar to story mode, but with more variety and player cooperation. Heists can be very lucrative.
Business Ventures:
•CEO/VIP Work: Register as a CEO or VIP to perform missions that pay well.
•Biker Businesses: Own and manage motorcycle club businesses like cocaine lockups or meth labs for passive income.
•Special Cargo: Buy and sell special cargo through warehouses.
•Nightclubs: Manage a nightclub for both passive income and missions.
•Adversary Modes, Races, and Jobs: These can be quick ways to make money, especially with double or triple cash events.
•Daily Objectives: Completing these gives you bonuses.
•Shark Cards: Real money can be spent to buy in-game currency, though this isn't recommended for those wanting to maintain an in-game economy.
Spending Money:
•Properties: Much like in single-player, buying properties can yield passive income, storage for vehicles, or serve as mission hubs.
•Vehicles: A wide range of vehicles, including special ones like super cars or weaponized vehicles, can be purchased or upgraded.
•Weapons, Armor, and Ammo: Essential for surviving in the online world.
•Character Customization: Clothes, tattoos, haircuts, etc., for personalization.
•Business Upgrades: Enhancing your business properties for higher output or efficiency.
Tips:
•Join Crews or Clubs: Being part of a group can help with missions or businesses, making money-making activities easier and more profitable.
•Weekly Updates: Rockstar often boosts earnings for certain jobs or events, so check the Rockstar Newswire for the best ways to earn money each week.
•Grind Smart: Focus on activities that give the highest return for your time, like heists or business sales during bonus periods.
•Save Money: Don't spend recklessly; reinvest in businesses or properties that provide passive income.
•Avoid Shark Cards: While they're an option for instant cash, learning the in-game economy can be morewarding and sustainable.
In both modes, the economy is designed to encourage players to engage with various aspects of the game, from heists to property management. The key is to balance earning with spending wisely to maximize your wealth and gameplay experience.
