What this does
An amortization schedule shows where every payment goes: early on, most of it is interest and little touches the balance; over time the split flips and principal dominates. Seeing that crossover is what makes the schedule useful — it explains why overpaying early saves so much more interest than overpaying late. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. For “amortisation table excel download”, the reliable version is a short checking loop, not just the first command that appears to work. Run it on a deliberately small range first, watch how the affected cells change, and only then apply the same setup to the full sheet. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. That is what makes a calculation you can defend to a CFO or an auditor useful in real work: repeatable, auditable, and not dependent on memory or luck.
A worked example
On a €250,000 loan at 3.8% over 25 years, the payment is about €1,292. In month one, interest is 250000×3.8%/12 ≈ €792 and only ≈€500 reduces the balance. By the final year almost the entire payment is principal. The yearly table above aggregates all 300 months so you can read the principal/interest split at a glance. Use this fixed-payment schedule to compare constant-rate loan offers and read the yearly principal, interest and balance. Fees, variable rates and extra payments need a separately extended model. It is the difference between knowing your monthly payment and understanding the assumptions behind your loan schedule. If there is any chance you will reuse this, drop it into a small template tab right now: a labelled input area on the left and the formula beside it, checked once against the tool above. Next time the same question comes up, the answer is a single paste away instead of a rebuild from memory.
In Google Sheets
Google Sheets support for this task has not been verified. Check the function, arguments and workflow in the target product before transferring the example. Matching formula notation does not establish identical behaviour. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. Treat “amortisation table excel download” as a small building block rather than a chore. Once the inputs sit in their own cells and the formula reads from them, the same setup answers a dozen related questions with a tweak, and Excel keeps every dependent figure current as the data changes. The tool above is there so you can rehearse and verify before committing anything to a real workbook; the steps and worked example are there so the logic sticks. Get it right once and it stops costing you time — it starts saving it, every time the question comes back around.
Common mistakes
- Letting rounding leave a tiny non-zero balance at the end — adjust the last payment to clear it.
- Applying the annual rate per month instead of rate/12.
- Forgetting that extra principal payments change every subsequent interest row.
- Building 360 rows by hand instead of copying one correct formula row down.
Frequently asked questions
Why is so much early payment interest?
Interest is charged on the outstanding balance, which is largest at the start. As the balance falls, the interest portion shrinks and principal grows.
Can this calculator model overpayments?
This calculator assumes equal monthly payments at a constant rate and has no extra-payment input. To compare overpayments, extend your worksheet schedule with the additional principal and recalculate the remaining balance and later interest.
Can I build this in Google Sheets?
Yes — PMT and the row formulas are identical in Google Sheets, so the same schedule works without any changes.
