Why this matters
Money and health decisions get made on rough mental maths far too often. Running the actual numbers takes thirty seconds and routinely changes the answer — whether that's a loan you shouldn't sign, a rate you should be charging, or a target you can realistically hit.
Common Mistakes to Avoid
Mixing monthly and annual rates
A 12% annual rate is 1% monthly, not 12% monthly. This single slip inflates results by an order of magnitude.
Ignoring fees, taxes and insurance
The headline number is rarely the number you pay. Add the extras before you compare two offers.
Rounding too early
Round only the final figure. Rounding intermediate steps compounds error across long schedules.

Technical Limitations & Boundary Conditions
- Results reflect the inputs and assumptions shown. Fees, taxes, rates, and personal circumstances can change the real-world outcome; verify important figures with the relevant provider or authority.
- Extreme values outside standard ranges may be constrained by device memory or numerical precision boundaries.
Key Terms Explained
- Principal
- The original amount borrowed or invested, before any interest is applied.
- APR
- Annual Percentage Rate — the yearly cost of a loan including fees, which is what makes it comparable between lenders.
- Compounding
- Earning interest on previously earned interest. Frequency (monthly vs annually) meaningfully changes the total.
- Amortisation
- The schedule showing how each payment splits between interest and principal over the life of a loan.
Pro Tips & Best Practices
- Enter exact numbers — the calculator handles rounding at the end for accuracy.
- Check the displayed units, dates, and assumptions; currency selection may format values without converting them.
- Treat estimates as planning aids and verify tax, fee, health, and lending inputs with authoritative sources.

Frequently Asked Questions
What is the snowball method?›
You pay minimums on everything and throw every extra rupee or dollar at the smallest balance first. It clears debts quickly, which keeps motivation high.
What is the avalanche method?›
You attack the highest interest rate first. It is mathematically optimal and always costs the least in total interest.
Which should I choose?›
Avalanche saves the most money. Snowball wins more often in practice because people stick with it. If the difference is small, choose snowball.
