Bankroll Tracking Spreadsheet: Ready Template for Serious Bettors (2026)

Professional bettors don’t operate without a spreadsheet. The spreadsheet isn’t “organizational luxury” — it’s the difference between real diagnosis and illusion.

This article delivers the spreadsheet template professional bettors use, with: - Automatic Kelly Criterion calculation - ROI by market / league / bet type - Closing Line Value (CLV) — metric proving real edge - Current and maximum drawdown - Bankroll curve

Why mental tracking doesn’t work

Typical bettor overestimates wins and underestimates losses. Behavioral psychology confirms: memory operates with positive bias.

Result: you think you have 5% ROI, but real spreadsheet shows -2% ROI. The difference is between healthy operation and bust.

Without objective tracking, you don’t know: - Where you win (which market / league / bet type) - Where you lose (and should abandon) - When you’re in abnormal drawdown - If your edge is real (positive CLV) or illusion (just luck)

How to use the spreadsheet (daily routine)

Before each bet

1. Calculate Kelly in Tab 4
2. Validate positive EV
3. Compare book odds with broker internacional de referência (record for CLV)

After each bet

1. Log in Tab 1 (date, market, stake, odds)
2. Note current broker internacional de referência odds

After the game

1. Note result and closing odds
2. CLV calculates automatically

Weekly review

1. Check dashboard
2. Identify: which market/league is profitable? Which loses?
3. Adjust next week’s plan

Monthly review

1. Calculate aggregate ROI
2. Compare with benchmark (3-7% professional)
3. Evaluate increasing/decreasing fractional Kelly

How to interpret numbers after 90 days

Scenario 1 — ROI 5%, CLV 3%

You have real edge. Continue, scale stake gradually.

Scenario 2 — ROI 15%, CLV -1%

You got lucky. Edge isn’t real. Results regress to mean (negative). Action: review method, keep stake low until CLV positive.

Scenario 3 — ROI -3%, CLV 2%

You have edge but short-term negative variance. Action: continue. In 200+ bets ROI converges to CLV.

Scenario 4 — ROI -5%, CLV -1%

No edge. Stop or radically refine method.

Conclusion

Bankroll spreadsheet isn’t “fancy bettor” luxury. It’s basic infrastructure.

Without it: - You don’t know if winning or losing - Can’t identify where you have edge - No data to adjust Kelly - Bets remain entertainment — not operation

Professional bettor spends 30 min/day updating spreadsheet. The difference between hobby and profession.

FAQ

Does the spreadsheet work for casino betting?

No. Casino has negative house edge. Bankroll spreadsheet is for markets where you have edge.

Can I use Google Sheets instead of Excel?

Yes. All formulas work identically.

Fill before or after the game?

Before the bet (initial log) + after result (update). Not filling before = you “forget” to log losses.

How many bets before spreadsheet shows relevant data?

Minimum 100. Ideally 300+. Below that, it’s variance.

Does the spreadsheet work for parlays?

Yes, but calculate combined probability (multiplication) and use Kelly fractional (25%) due to higher variance.
