Free loan & mortgage calculator — payment, interest, amortization
Strumentoolis Loan Calcolatore computes fixed-rate loan payments using the standard amortization formula. Works for mortgages, auto loans, student loans, and personal loans. See your monthly payment, total paid over the life of the loan, total interest, and a year-by-year breakdown.
What you get
- Monthly P&I payment — The headline number
- Total paid over loan term — Principal + all interest
- Total interest — How much the loan really costs
- Interest as % of principal — Useful comparison metric
- Amortization schedule — First year + last year, showing how payments shift from mostly-interest to mostly-principal
How to use this tool
- 1
Enter loan amount
Type the total amount you're borrowing (the principal). Works for mortgages, auto loans, personal loans, student loans.
- 2
Set the interest rate
Annual interest rate as a percentage (e.g., 5.5). This calculator uses fixed-rate amortization — the math for standard loans.
- 3
Choose loan term
Length of the loan in years. Common: 30 or 15 for mortgage, 5 for auto, 10 for student.
- 4
Read your monthly payment
The headline number is your monthly payment. Below you'll see total paid over the full term and total interest — often more than the loan itself for long-term loans.
Typical loan types and terms
- 30-year fixed mortgage — Most common in the US. Lower payment, higher total interest.
- 15-year fixed mortgage — Higher payment, ~50% less total interest.
- 5 or 7-year adjustable (ARM) — Fixed rate for initial period, then adjusts. Not modeled here (use fixed rate).
- Auto loan — 3–7 years typical. Shorter = less interest, higher payment.
- Student loan — 10 years standard (US federal). Can extend to 20–25 years.
- Personal loan — 2–7 years. Higher interest than secured loans.
How to save on interest
- Shorter term — A 15-year mortgage vs 30-year saves ~50% of total interest
- Lower rate — Every 1% reduction on a 30-year mortgage saves ~10–15% of total cost
- Extra payments — Any amount above minimum goes 100% to principal, accelerating payoff
- Bi-weekly payments — Paying half your monthly payment every 2 weeks = 13 monthly payments/year = 4–6 years off a 30-year mortgage
- Refinance when rates drop — 1% lower rate on a large loan often pays back closing costs within 2 years
