About this tool
Plan FASTag top-ups from your toll usage: daily burn, days of balance left, recommended recharge and the return-journey saving.
The Fastag Recharge Planner converts a toll routine into a FASTag burn rate — cost per journey, spend per day, month and year — and returns the date the current balance runs down to your chosen buffer plus the top-up that will cover the next stretch. It applies the return-journey rule in the National Highways Fee (Determination of Rates and Collection) Rules, 2008, where a return trip completed within 24 hours costs one and a half one-way fares instead of two. Aimed at daily commuters and anyone tired of a tag going low at the plaza.
Open Fastag Recharge Planner on AltFTool — it loads instantly in your browser.
Enter the One-way toll fee (INR), your Round trips per week (the label reads 'Single crossings per week' when the return box is unticked) and your Current FASTag balance (INR).
Tick 'I come back through the same plaza within 24 hours' to price a round trip at 1.5 one-way fares, then set the Buffer you never want to go below (INR), 'I want each recharge to last (days)' and a Local monthly pass price if one is offered.
Recommended top-up appears with Burn per day, Days of cover left, a 'Recharge by' date, 'That top-up buys', the Return-journey concession saving and the Monthly pass verdict, plus a 'Next six recharges' table; Copy result copies the plan.
Prices a same-day round trip at 1.5 fares, the way the NH fee rules do.
Says which day the balance reaches your buffer and what to load.
Compares a monthly pass price against your actual monthly toll spend.
Not for cars, jeeps and vans. NHAI withdrew the minimum-balance requirement for fee class 4 vehicles in February 2021, so a tag works as long as the balance covers the crossing. Individual issuing banks still hold a security deposit and some keep their own threshold, and a negative balance gets the tag blocked.
One and a half times the one-way fee, provided the return journey is completed within 24 hours through the same plaza, under the National Highways Fee Rules, 2008. That is a 25% saving against paying two single fares, which is why a daily commuter should count round trips rather than crossings.
Enough to cover your daily burn for as long as you want to go between top-ups. If you cross a ₹85 plaza and return the same day, five days a week, the burn is roughly ₹91 a day, so a month of cover needs about ₹2,800. The calculator rounds the figure up to the nearest hundred.
At many national highway plazas, yes — the fee rules provide a discounted monthly pass for a non-commercial vehicle whose owner lives within 20 km of the plaza, with proof of residence. The pass price is notified plaza by plaza; enter it in the planner and it will tell you whether it beats what you currently spend.
