Latest guides
Practical articles that answer first, then walk through examples.
Currency conversion fees vs mid-market rate
Why bank FX rates differ from online converters. See an example 250 USD conversion and how a percentage fee changes the result.
Flat vs reducing-balance interest
Same ₹100,000 at 12% for 12 months: compare flat interest math with the reducing-balance EMI our calculator actually computes.
How loan amortization works
Walk a 12-month ₹120,000 loan at 10%: EMI ₹10,549.91 and a schedule that shows principal, interest, and balance each month.
How loan tenure affects EMI and total interest
Same ₹500,000 loan at 10%: compare EMI and total interest across 2–20 year tenures using the reducing-balance calculator.
How many days between two dates
From 1 Jan 2026 to 1 Apr 2026 is 90 calendar days (3 months). Add or subtract days, or count weekdays only, with the date difference calculator.
How prepayment changes EMI and total interest
₹200,000 at 10% for 36 months: with ₹2,000 monthly prepayment the loan clears in 27 months and total interest falls. EMI stays ₹6,453.44.

Frequently asked questions
Are the tools really free?
Yes. Core calculators and generators are free to use. Optional ads may appear after you consent to cookies.
Do I need an account?
No. There is no sign-up wall. Open a tool and start calculating immediately.
Is my data sent to a server?
Most tools calculate in your browser. When a server is required (for example live currency rates), we say so clearly and cache responsibly.
Which languages are supported?
English, Spanish, Portuguese, Indonesian, Vietnamese, Turkish, Arabic, Hindi, and Urdu, including RTL for Arabic and Urdu.
Can I trust tax or loan results?
Treat results as estimates. Tax slabs and legal thresholds come from published sources we verify before enabling a country.
Will more tools be added?
Yes. The registry is designed so new calculators ship with localized slugs, SEO content, and tests.
