Check the record: The lender’s EMI is different from your spreadsheet
Use the exact sanctioned principal, current annual rate, remaining instalments and repayment frequency from the lender’s documents. Check whether insurance, fees, staged disbursement or pre-EMI changes the balance being modelled.
Take the next step: The lender’s EMI is different from your spreadsheet
Request the lender’s amortisation schedule and compare the first few rows with your formula. Ask which rate, day-count/rounding convention and reset date explain any remaining difference.
Confirm the resolution: The lender’s EMI is different from your spreadsheet
Your model and the lender schedule use the same principal, rate and tenure assumptions, and any residual rounding difference is understood.
Escalate with evidence: The lender’s EMI is different from your spreadsheet
If a material unexplained difference remains, ask the lender to explain it in writing before signing or making a prepayment decision. Do not “fix” your spreadsheet by forcing it to match an unexplained number.
