Simple, focused calculators built to help you understand your numbers and explore your options.
Each calculator focuses on a specific question, using your own numbers.
Compare buying vs. renting to see which may come out ahead — with a projected break-even year, net worth estimates, year-by-year projections, and sensitivity analysis showing how changes in key variables can shift the break-even point.
Explore your path to financial independence. Estimate your retirement age based on your savings, withdrawal strategy (3.5–4%+), and life events — or set a target age to see what it takes to get there with Monte Carlo simulation.
Compare estimated repayment plans side-by-side — Standard, Extended, IBR, and RAP. Explore how extra payments could reduce your interest, view step-by-step breakdowns, and check PSLF eligibility.
Estimate your take-home pay for W-2 and 1099 income — with federal, state, FICA, self-employment tax, deductions, and a side-by-side comparison.
Estimate your freelance tax bill — including self-employment, federal, and state income taxes, quarterly payments, and projected take-home pay.
Numbers are presented clearly, with explanations that make them easy to follow.
