Price Increase Calculation
This tool applies an increase at the rate you set. Choose one period for a simple percentage rise; choose several periods and it applies the rate compounding each period. Compounding matters because each successive increase builds on the already-grown amount, making the total higher than a simple sum. For example, 5% monthly over 12 months is about 79.6%, not 60%.
Where to Use It
- Updating price lists: quickly find the new amount when raising product and service prices by a set rate.
- Rent and subscriptions: apply an annual increase in contracts to compute the new figure.
- Budget projection: forecast next-period costs with an estimated increase.
- Pay reviews: compare periodic raise scenarios.
Important Note
This tool does not use official inflation data; it only does math with the rates you enter. Where increases are capped by law (for example a statutory ceiling on residential rent), you must follow the current regulation; the result here is not binding and is informational only. For exact rates and legal ceilings, consult the relevant official sources or your advisor. For percentage operations, see our Percentage Calculator.
