How it works
We invert the amortization formula to find the number of months needed to clear the balance, accounting for interest on the remaining balance each month.
Formula
n = −ln(1 − rB/P) / ln(1+r), where B is balance, P is monthly payment, r is monthly rate.
Worked example
SAR 15,000 at 24% with SAR 1,000/mo ≈ 18 months and ~SAR 3,000 in interest.
FAQ
- What if I pay only the minimum?
- It can take years and double the balance in interest. Pay more whenever you can.
- Are fees included?
- No — only interest and balance. Add any fees to the balance manually.
- How do I cut interest?
- Pay more monthly, do a balance transfer, or stop new purchases.
