Worked example: changing one monthly extra payment
Illustrative balance CHF 220,000.00, constant annual rate 4.5% and repayment term 27 years. The currency labels this model; it is not a typical local loan or a currency conversion.
| Model | Original | Revised |
|---|---|---|
| Extra each month | CHF 100.00 | CHF 150.00 |
| Planned monthly payment | CHF 1,274.19 | CHF 1,324.19 |
| Payment months | 279 | 261 |
| Total modelled interest | CHF 134,931.06 | CHF 125,137.46 |
A larger chosen monthly extra finishes this model sooner. Whether it fits your budget or lender's terms needs a separate check. Fees, overpayment limits and changing rates are excluded; the final payment can be smaller.
When keeping your own plan, the original remains recorded. A later revision shows the changed inputs and its own calculation date and engine version. Changes in balance, rate, term or engine do not isolate the effect of extra payment alone.
