Frequently Asked Questions
Start with your goal: use the mortgage calculator for home buying, compound interest for savings growth, loan EMI for loan payments, retirement calculator for nest egg planning, ROI for investment returns, and the tax calculator for tax estimates.
Yes. Our tax calculator uses 2024 federal income tax brackets published by the IRS, supporting all filing statuses (single, married filing jointly, married filing separately, head of household) and both standard and itemized deductions.
The mortgage calculator includes fields for property tax rate, homeowner's insurance, PMI (private mortgage insurance for down payments under 20%), and HOA fees. All are factored into the total monthly payment breakdown.
The compound interest, ROI, loan EMI, tip, and currency converter calculators work with any currency. The mortgage, tax, salary, and retirement calculators currently use US-specific conventions and tax rules.
Transparency is our core principle. By showing the exact formula used, you can verify results independently, understand how changing inputs affects outcomes, and build genuine financial literacy rather than blindly trusting a black box.
The inflation calculator directly measures purchasing power loss over time. The retirement savings calculator includes an inflation rate input to show inflation-adjusted projections. Other calculators use nominal values — use the inflation calculator alongside them for real-value estimates.
Currency values are precise to 2 decimal places and interest rates to 4+ decimal places. Amortization schedules are computed so the final balance reaches exactly $0.00. We never use floating-point shortcuts that cause rounding errors.
