Weekly cadence and yearly total
A loan paid monthly makes 12 payments per year, while weekly payments create 52 events. The “even” option spreads the same annual amount: monthly × 12 ÷ 52. For a ₨250,000 balance at 6.25% APR, an even weekly plan keeps cash flow smoother while maintaining comparable annual outlay.
Accelerated weekly adds an extra month
The “accelerated” option uses monthly ÷ 4, producing 13 monthly-equivalent payments each year. If the baseline payment were ₨1,540, accelerated weekly targets about ₨385 per week. Over 52 weeks, that totals roughly ₨20,020 versus ₨18,480 monthly, adding about one extra payment annually.
Interest cost reacts to earlier principal reduction
Each period’s interest equals balance × periodic rate. Reducing principal sooner lowers future interest charges. Weekly schedules typically cut interest because principal declines in smaller, earlier steps. When APR is 6.25%, the weekly rate is 0.0625 ÷ 52 ≈ 0.001202, so every ₨10,000 of balance costs about ₨12.02 per week.
Small extras compound into large savings
An extra ₨25 per week equals ₨1,300 per year. Applied from the first week, that extra principal reduction can remove months of repayment near the end of the schedule, where interest still accrues on a larger remaining balance. Testing ₨25, ₨50, and ₨100 shows how payoff dates and interest totals shift.
Reading results and exporting schedules
The results summarize payoff date, total paid, and total interest for both plans. The calculator also reports days saved, helping translate rate math into calendar impact. With a 30‑year baseline, even a 90‑day improvement can feel meaningful. The table preview shows the first 26–104 rows, while CSV exports include every period for auditing. Rounding to cents mirrors common statements and helps reconcile totals. The PDF provides a printable snapshot for budgeting discussions, lender reviews, or personal records, while the chart highlights balance declines week by week. Use multiple scenarios to find a weekly amount that fits income and goals comfortably.
Even weekly spreads the same annual total across 52 payments. Accelerated weekly uses monthly ÷ 4, creating 13 monthly-equivalent payments each year, which often reduces payoff time and interest.
Not always. Savings depend on the weekly amount. If weekly payments are too small, the schedule can finish later and may cost more interest. Compare totals and payoff dates shown in the results.
If your chosen weekly payment is lower than the baseline’s implied weekly pace, principal falls more slowly. That extends the payoff date and increases interest. The warning messages help flag weak payment settings.
Interest is computed as current balance × periodic rate. The periodic rate is APR ÷ 12 for monthly and APR ÷ 52 for weekly. Each payment first covers interest, then reduces principal.
Rounding matches how most lenders post interest and payments. It can slightly change the final period amount by a few cents and helps your CSV/PDF totals align with typical account statements.
The PDF is designed to stay readable on one page, so it prints only the first portion of the schedule. Use the CSV export for the complete table covering every week or month.
