Personal loan calculator for Guatemala
A personal loan is unsecured consumer credit: you receive cash today and repay it in fixed installments (French amortization) plus interest, an origination fee, and often monthly insurance. This tool estimates the payment, total cost, and an approximate annual cost (CAT-like) so you can compare banks, cooperatives, and lenders.
For Q10,000 at 24% annual over 24 months, with a 2% origination fee and Q50/month insurance, the base payment is Q528.71, the payment with insurance is Q578.71, and total cost is about Q14,089 (approx. annual cost 20.5%). Change rate, term, and fees to see the real impact.
What this calculator returns
- Base monthly payment (principal + interest)
- Payment with insurance or other fixed monthly charges
- Origination fee (% of principal)
- Total interest over the term
- Total cost = installments + insurance + fee
- Approximate APR-like cost for educational comparison
Payment formula (French amortization)
r = annual rate / 12 / 100
Payment = P × [r(1+r)^n] / [(1+r)^n − 1]
P is principal, r is the monthly rate, and n is the term in months. If the rate is 0, payment is simply P ÷ n.
Total cost = (payment × n) + (monthly insurance × n) + origination fee
Approx. annual cost = ((total cost − P) / P) × (12 / n) × 100
The CAT/APR figure here is an educational approximation. A lender’s contractual APR may use another convention and treat insurance differently.
Worked example (Q10,000)
Inputs: Q10,000 · 24% annual · 24 months · 2% fee · Q50/month insurance
- Monthly rate r = 0.24 / 12 = 0.02
- Base payment ≈ Q528.71
- Payment with insurance ≈ Q578.71
- Origination fee = 2% × Q10,000 = Q200
- Total interest ≈ Q2,689.06
- Total insurance = 50 × 24 = Q1,200
- Total cost ≈ Q14,089.06
- Approximate annual cost ≈ 20.45%

How to lower the real cost of credit
- Compare the same term and similar payment across at least three lenders: not only the advertised rate.
- Ask for 0% origination promotions; fees of Q200–Q1,500 show up in total cost.
- A longer term lowers the payment but usually raises total interest: check total cost, not comfort alone.
- Confirm whether insurance is mandatory, optional, or already covered.
- If you can prepay principal, use the early loan payoff calculator and the amortization schedule.
- Stress-test affordability with debt-to-income and debt payoff.
Common mistakes
- Comparing nominal rate only while ignoring fees, insurance, and term.
- Choosing the longest term just because the payment “fits.”
- Forgetting net disbursement may be principal − fee if the fee is deducted upfront.
- Not requesting the contractual APR / total cost in writing.
- Using personal credit to shuffle cheaper debt without a plan.

This calculator is educational. It is not a credit offer or personalized advice. Real rates, fees, and insurance depend on the lender, your credit profile, and the terms you sign. Always confirm the disclosure sheet and contractual APR before signing.
FAQ
With the French amortization PMT formula: monthly rate = annual rate ÷ 12 ÷ 100; the payment spreads principal and interest over n fixed months. Add origination fee and monthly insurance to estimate true cost.
It annualizes the extra cost (interest + insurance + fee) relative to principal and term for comparison. It does not replace the lender’s contractual APR.
At the same rate, 12 months means a higher payment and lower interest; 36 months lowers the payment but usually raises total interest and insurance cost. Run your numbers in the table and calculator.
It depends on the lender. Here it is added as an upfront cost. If deducted from disbursement, you receive less cash while the payment is still based on the full principal.
Yes. Q40–Q100 per month multiplies cost on long terms. Ask if it is required and whether you can shop it separately.
The payment math is similar, but auto and mortgage products use different terms and collateral rules. Prefer the Guatemala mortgage calculator or auto loan calculator.
