About BufoIndex
BufoIndex is a personal-finance calculator site focused on helping people make informed decisions about paychecks, retirement, and investment portfolios. Its tools run entirely in the user’s browser, and scenarios can be shared through a URL, making it easy to revisit or compare plans. Each calculator also explains the formulas behind its results.
The Paycheck Allocator helps users divide monthly income among fixed costs, tax-advantaged accounts, and flexible spending. It accounts for tax brackets and orders allocations by after-tax return. The Retirement Calculator uses Monte Carlo modeling to explore retirement scenarios, incorporating Social Security and healthcare costs and allowing side-by-side comparisons. For investors managing multiple accounts, the Portfolio Rebalancing tool directs new deposits toward underweight asset classes. Taxable selling is turned off by default, and the calculator provides account-placement advice.
Together, these tools offer practical ways to model personal-finance choices and compare possible approaches. BufoIndex identifies its source code as available under the AGPL-3.0 license.
