BigVest: Compound Yield

BigVest is a personal finance toolkit with eight calculators covering the full spectrum of financial planning. The Compound Yield engine projects investment growth with configurable contributions, compounding frequency, fee drag, and inflation adjustment and generates a year-by-year breakdown table. A six-question Risk Profiler scores your tolerance and recommends a stock, bond, cash, and alternatives allocation, while the Portfolio Rebalancer calculates exact buy and sell amounts to bring any portfolio back to its targets. The Goal Planner works backwards from a savings target to find the required monthly contribution or annual return rate, and the FIRE Projector estimates your financial independence number, projected retirement age, and whether withdrawals are sustainable to age 90. The Debt Payoff Strategist compares Snowball and Avalanche strategies with total interest saved, and the Monte Carlo tool runs 1,000 offline simulations showing 10th, 50th, and 90th percentile outcomes alongside a probability-of-success percentage.
