Our methodology
All calculations follow industry-standard financial formulas. The compound interest formula A = P(1 + r/n)^(nt) is from the SEC's investor.gov. Loan amortization uses the standard formula M = P × [r(1+r)^n] / [(1+r)^n − 1]. Retirement projections use the 4% safe withdrawal rule. Our code is open source and unit-tested.
