1 toolFree Finance Calculators for Loans, Investments and Savings
Atoolix provides free online finance calculators for comparing loan repayments, estimating investment growth, and planning savings or retirement targets. Enter your own assumptions and see the calculated result directly in your browser.
Each calculator is intended for a specific type of financial calculation. Choosing the right tool matters: an EMI calculator models loan repayments, while SIP, XIRR, CAGR, Lumpsum, and fixed-deposit calculators answer different investment or savings questions.
Investment Return Calculators
SIP is suited to recurring contributions, XIRR to cash flows occurring on different dates, CAGR to annualized growth between two values, and Lumpsum to one-time investment growth under an assumed return.
Savings and Retirement Calculators
Estimate fixed-deposit maturity, compare compound growth, and explore retirement targets using your own contribution, return, time-period, and target assumptions.

CAGR Calculator: use it to calculate the annualized growth rate between an initial value and a final value over a defined period.
Lumpsum Calculator: use it to estimate how a one-time investment may grow over a chosen period at an assumed annual return.
Which Savings Calculator Should You Use?
