In Excel: compute the payment with =PMT(rate/12, years*12, -amount), then split each month into interest (=balance*rate/12) and principal (=payment-interest).

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. Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “excel credit card payoff template”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the tool above before you touch the real workbook. 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. The point is a workflow that saves repeating the same clicks every week, but the practical win is that someone else can open the file and understand what happened without asking you.
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 an amortization schedule to compare the true cost of loan offers, to see the impact of overpayments, or to plan an early payoff. It is the difference between knowing your monthly payment and understanding your loan. 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
Everything above works in Google Sheets too. Excel and Sheets share the formula syntax used here; only the surrounding menus are arranged differently. That portability is deliberate — learn it once and it follows you between the two tools and across Windows and Mac. 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. Here is the takeaway for “excel credit card payoff template”: copy the answer if you are busy, but if you have a spare few minutes, rebuild the example in Excel yourself with the tool above open beside it. That single pass — type it, run it, watch the result move when you change an input — is what turns a formula you found into a technique you trust. Keep your inputs labelled and referenced, never hard-coded, and the same sheet stays correct and auditable as it grows. Done that way, you will not need to look this up again, and you will be the person others ask.
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.
How much does overpaying save?
A lot, and most when done early, because every euro of extra principal stops accruing interest for the entire remaining term. The schedule lets you test it directly.
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.
