Choose a financial calculator by decision
Calcixa’s finance collection separates borrowing, saving, investing, tax, purchasing-power, and business questions so that one formula is not used for a different decision.
Borrowing and repayment
Use EMI for a level fixed-rate payment, Loan Eligibility for a preliminary affordability scenario, and Loan Amortization when you need the balance path or an extra-payment comparison. A lender’s fees, underwriting, and contract remain authoritative.
Saving and investment scenarios
FD, RD, SIP, Compound Interest, Simple Interest, Savings Goal, ROI, and Inflation answer different timing and cash-flow questions. Their rates are assumptions, not guaranteed outcomes.
Tax and business arithmetic
GST separates inclusive or exclusive tax amounts; Profit Margin distinguishes margin from markup; Discount applies reductions and optional tax in the order shown. Verify current tax classification and commercial rules independently.
Before using a result
- Match the formula to the cash-flow timing.
- Use the rate type and compounding frequency actually quoted.
- Compare total cost or contribution—not only the headline result.
- Read the tool-specific assumptions before making a decision.
Each tool includes a practical guide, common mistakes, sources, and limitations. Read our calculation and tool methodology for testing, rounding, privacy, and corrections.
